William Lane Craig explains how to structure a conversation with an atheist

Man teaching a woman how to shoot a firearm accurately
Man teaching a woman how to shoot a firearm accurately

It’s from his latest question and answer on the newly redesigned Reasonable Faith website.

Here’s the question in brief:

I must say I feel completely defeated and I could use your help and insight. I had a discussion over God’s existence tonight and totally botched it!! I feel I did a dis-service to the reasonableness of the Christian worldview.

I’ve been studying apologetics for quite some time. I felt I knew the material pretty well. Now I’m not so sure. Dr. Craig, I know you’re one of the great Christian debaters. When you were younger, did you ever feel you completely botched a debate and felt like a failure? That is how I feel right now!!

Dr. Craig’s response, in part:

So right at the beginning of the conversation, when he says that he is an atheist, it would be important to understand exactly what he means by that. Is he just agnostic or does he claim to know that God does not exist? If the latter, what justification does he have for so radical a position? You might comment on how difficult it is to prove that God does not exist and so express your interest in hearing his arguments against the existence of God. If he just says that “there’s no real evidence for the existence of God,” that’s a perfect opening for you to say, “Wait a minute! You’re a criminal analyst, right? As a criminologist, you must know that absence of evidence is not evidence of absence. I want to hear your evidence against God.”

Or again, when he makes a claim like “there’s no way to know if there’s absolute truth,” you ought to be ready for such an assertion. Take out a pen and write his claim on a paper: “There’s no way to know if there’s absolute truth.” Then show it to him and ask, “Is that absolutely true?” If not, then is it just his opinion? If it is absolutely true, then how does he know it? Isn’t his position self-refuting? Be nice about it. Say, “I’m really trying to understand how your position isn’t self-referentially incoherent.”

When he says, “not knowing is okay and we should be more willing to accept uncertainty,” you should respond, “Have I ever claimed to know with certainty that God exists? I’m just saying that on balance God’s existence is more probable than not.” Ask him if he wouldn’t agree with that. If not, why not?

If he demands evidence of God’s existence, then you should be ready and waiting. I don’t get the impression, Marshall, that you have memorized any arguments and their respective premises. If you have them memorized, that’s the best antidote for becoming tongue-tied. You need to have memorized: “Why, I can think of at least five arguments for God’s existence!” When he says, “Yeah, like what?”, then you recite your list of arguments that you’ve memorized:

1. God is the best explanation for why anything at all exists rather than nothing.

2. God is the best explanation of the origin of the universe.

3. God is the best explanation of the fine-tuning of the universe for intelligent life.

4. God is the best explanation of objective moral values and duties.

5. The very possibility of God’s existence implies that God exists.

For the average unbeliever to hear even a list such as this is overwhelming. If he then wants to talk about one of them, recite from memory the premises of that argument, e.g.,

1. If God does not exist, objective moral values and duties do not exist.

2. Objective moral values and duties do exist.

3. Therefore God exists.

You may even want to write the premises out on a piece of paper for him to look at.

If anyone ever responds to your arguments by attacking or blaming you personally, like saying you “must live with a lot of guilt and that’s why [you] probably feel the need for God,” just smile and say, “Are you not familiar with the logical fallacy of argument ad hominem?” (It’s evident by this point that you’re dealing with a really snarky person and therefore can afford to be more confrontational.) “Even if what you said were true—which it isn’t—, it has no relevance to the soundness of my argument. If you want to deny the conclusion of my argument, then you must think that one of its premises is false. So I want you to tell me which premise you think is false and why.” If you have these sentences memorized, you won’t feel tongue-tied when he makes his accusations.

In my opinion, Dr. Craig left out a very important point, which is that you need to structure the conversation so that you major in the majors and purposefully set aside any discussion of minor issues. If your atheist wants to discuss whether she is going to Hell, you respond by explaining that Hell is only a problem if the New Testament is an accurate description of God, which depends on whether God exists at all. So we start with God’s existence, and Dr. Craig’s 5 arguments. And, as Dr. Craig says, we focus the atheist on the discussion of whether God exists, and what evidence he has against God’s existence.

I would also say that you need to be ready to discuss the scientific evidence related to the origin of the universe, the fine-tuning, the origin of life, habitability, etc. You need to be able to retrace the histories of the discoveries that lead the majority of scientists to accept this data, and name the scientists. That way, when your atheist denies your evidence, you can ask them why they hate science. This is the most powerful argument for theism, in my opinion – the opposition to mainstream science that atheists must necessarily commit to in order to be atheists.

Also, you need to know the minimal facts case for the resurrection of Jesus, which doesn’t even assume that the Bible is inerrant or inspired or even generally reliable. And finally, you’ll need to know how to spot a self-refuting claim and how to respond to philosophical objections to God’s existence: the problem of evil, the hiddenness of God, physicalist conceptions of mind, etc. But the main point is that you are always on the topic of whether God exists, where your evidence is strongest, until you get that as a solid admission. Never move off that until you get that admission. The Bible should not be cited until you get a solid admission from your opponent on the existence of God.

How the WMAP satellite confirmed nucleosynthesis predictions and falsified atheism

Christianity and the progress of science
Christianity and the progress of science

Prior to certain scientific discoveries, most people thought that the universe had always been here, and no need to ask who or what may have caused it. But today, that’s all changed. Today, the standard model of the origin of the universe is that all the matter and energy in the universe came into being in an event scientists call “The Big Bang”. At the creation event, space and time themselves began to exist, and there is no material reality that preceded them.

So a couple of quotes to show that.

An initial cosmological singularity… forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity… On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.

And another quote:

[A]lmost everyone now believes that the universe, and time itself, had a beginning at the big bang.

So, there are several scientific discoveries that led scientists to accept the creation event, and one of the most interesting and famous is the discovery of how elements heavier than hydrogen were formed.

Nucleosynthesis: forming heavier elements by fusion
Nucleosynthesis: forming heavier elements by fusion

Here’s the history of how that discovery happened, from the National Aeronautics and Space Administration (NASA) web site:

The term nucleosynthesis refers to the formation of heavier elements, atomic nuclei with many protons and neutrons, from the fusion of lighter elements. The Big Bang theory predicts that the early universe was a very hot place. One second after the Big Bang, the temperature of the universe was roughly 10 billion degrees and was filled with a sea of neutrons, protons, electrons, anti-electrons (positrons), photons and neutrinos. As the universe cooled, the neutrons either decayed into protons and electrons or combined with protons to make deuterium (an isotope of hydrogen). During the first three minutes of the universe, most of the deuterium combined to make helium. Trace amounts of lithium were also produced at this time. This process of light element formation in the early universe is called “Big Bang nucleosynthesis” (BBN).

The creation hypothesis predicts that there will be specific amounts of these light elements formed as the universe cools down. Do the predictions match with observations?

Yes they do:

The predicted abundance of deuterium, helium and lithium depends on the density of ordinary matter in the early universe, as shown in the figure at left. These results indicate that the yield of helium is relatively insensitive to the abundance of ordinary matter, above a certain threshold. We generically expect about 24% of the ordinary matter in the universe to be helium produced in the Big Bang. This is in very good agreement with observations and is another major triumph for the Big Bang theory.

Moreover, WMAP satellite measurements of mass density agree with our observations of these light element abundances.

Here are the observations from the WMAP satellite:

Scientific observations match predictions
Scientific observations match predictions

And here is how those WMAP measurements confirm the Big Bang creation event:

However, the Big Bang model can be tested further. Given a precise measurement of the abundance of ordinary matter, the predicted abundances of the other light elements becomes highly constrained. The WMAP satellite is able to directly measure the ordinary matter density and finds a value of 4.6% (±0.2%), indicated by the vertical red line in the graph. This leads to predicted abundances shown by the circles in the graph, which are in good agreement with observed abundances. This is an important and detailed test of nucleosynthesis and is further evidence in support of the Big Bang theory. 

“An important and detailed test”.

For completeness, we should learn how elements heavier than these light elements are formed:

Elements heavier than lithium are all synthesized in stars. During the late stages of stellar evolution, massive stars burn helium to carbon, oxygen, silicon, sulfur, and iron. Elements heavier than iron are produced in two ways: in the outer envelopes of super-giant stars and in the explosion of a supernovae. All carbon-based life on Earth is literally composed of stardust.

That’s a wonderful thing to tell a young lady when you are on a date: “your body is made of stardust”. In fact, as I have argued before, this star formation, which creates the elements necessary for intelligent life, can only be built if the fundamental constants and quantities in the universe are finely-tuned.

Now, you would think that atheists would be happy to find observations that confirm the origin of the universe out of nothing, but they are not. Actually, they are in denial.

Here’s a statement from the Secular Humanist Manifesto, which explains what atheists believe about the universe:

Religious humanists regard the universe as self-existing and not created.

For a couple of examples of how atheistic scientists respond to the evidence for a cosmic beginning, you can check out this post, where we get responses from cosmologist Lawrence Krauss, and physical chemist Peter Atkins.

You cannot have the creation of the universe be true AND a self-existing, eternal universe ALSO be true. Someone has to be wrong. Either the science is wrong, or the atheist manifesto is wrong. I know where I stand.

So, there are several scientific discoveries that led scientists to accept the creation event, and one of the most interesting and famous is the discovery of the cosmic microwave background radiation.

Here’s the history of how that discovery happened, from the American Physical Society web site:

Bell Labs radio astronomers Arno Penzias and Robert Wilson were using a large horn antenna in 1964 and 1965 to map signals from the Milky Way, when they serendipitously discovered the CMB. As written in the citation, “This unexpected discovery, offering strong evidence that the universe began with the Big Bang, ushered in experimental cosmology.” Penzias and Wilson shared the Nobel Prize in Physics in 1978 in honor of their findings.

The CMB is “noise” leftover from the creation of the Universe. The microwave radiation is only 3 degrees above Absolute Zero or -270 degrees C,1 and is uniformly perceptible from all directions. Its presence demonstrates that that our universe began in an extremely hot and violent explosion, called the Big Bang, 13.7 billion years ago.

In 1960, Bell Labs built a 20-foot horn-shaped antenna in Holmdel, NJ to be used with an early satellite system called Echo. The intention was to collect and amplify radio signals to send them across long distances, but within a few years, another satellite was launched and Echo became obsolete.2

With the antenna no longer tied to commercial applications, it was now free for research. Penzias and Wilson jumped at the chance to use it to analyze radio signals from the spaces between galaxies.3 But when they began to employ it, they encountered a persistent “noise” of microwaves that came from every direction. If they were to conduct experiments with the antenna, they would have to find a way to remove the static.

Penzias and Wilson tested everything they could think of to rule out the source of the radiation racket. They knew it wasn’t radiation from the Milky Way or extraterrestrial radio sources. They pointed the antenna towards New York City to rule out “urban interference”, and did analysis to dismiss possible military testing from their list.4

Then they found droppings of pigeons nesting in the antenna. They cleaned out the mess and tried removing the birds and discouraging them from roosting, but they kept flying back. “To get rid of them, we finally found the most humane thing was to get a shot gun…and at very close range [we] just killed them instantly. It’s not something I’m happy about, but that seemed like the only way out of our dilemma,” said Penzias.5 “And so the pigeons left with a smaller bang, but the noise remained, coming from every direction.”6

At the same time, the two astronomers learned that Princeton University physicist Robert Dicke had predicted that if the Big Bang had occurred, there would be low level radiation found throughout the universe. Dicke was about to design an experiment to test this hypothesis when he was contacted by Penzias. Upon hearing of Penzias’ and Wilson’s discovery, Dicke turned to his laboratory colleagues and said “well boys, we’ve been scooped.”7

Although both groups published their results in Astrophysical Journal Letters, only Penzias and Wilson received the Nobel Prize for the discovery of the CMB.

The horn antenna was designated a National Historic Landmark in 1990. Its significance in fostering a new appreciation for the field of cosmology and a better understanding of our origins can be summed up by the following: “Scientists have labeled the discovery [of the CMB] the greatest scientific discovery of the 20th century.”8

It’s the greatest scientific discovery of the 20th century.

In the New York Times, Arno Penzias commented on his discovery – the greatest discovery of the 20th century – so:

The best data we have [concerning the Big Bang] are exactly what I would have predicted, had I nothing to go on but the five books of Moses, the Psalms, the bible as a whole.

Just one problem with the greatest scientific discovery of the 20th century: atheists don’t accept it. Why not?

Here’s a statement from the Secular Humanist Manifesto, which explains what atheists believe about the universe:

Religious humanists regard the universe as self-existing and not created.

Bible study: what difference does the resurrection of Jesus make?

Bible study that hits the spot
Bible study that hits the spot

Here’s an article from Bible.org, written by famous New Testament manuscript expert Dan Wallace. (H/T Eric Chabot, Ratio Christi OSU)

There is a lot in this article, but I’ll just snip out one that I think is interesting.

First, what does the Old Testament say about the doctrine of the resurrection in Judaism?

The resurrection of the dead was not plainly revealed in the OT until very late in salvation history. It was not until the Jews were taken in captivity, in the sixth century BC, that this was clearly articulated. Daniel 12:1-2 is the principal text: it speaks of the resurrection of both the righteous and the unrighteous:

At that time shall arise Michael, the great prince who has charge of your people. And there shall be a time of trouble, such as never has been since there was a nation till that time; but at that time your people shall be delivered, every one whose name shall be found written in the book. And many of those who sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt. (RSV)

Why was it not clearly revealed till then? It was not revealed until there was a felt need for it. When the Jews had no present (because of the captivity) they had to look to the future. The revelation of the resurrection came at precisely the time when the people of God needed hope for the future.

What is significant about this is how masterful are God’s insights into human nature. In the NT era, one religious group in Palestine did not embrace the resurrection as a true doctrine: the Sadducees (cf. Mark 12:18)–that is why they were “sad, you see!” The Sadducees were in charge of the temple. They derived their income from the sacrifices. In a sense, they were the precursors to modern TV evangelists. They had it good! They were the rich aristocracy that ran the place.

Those who have it good in this life don’t often long for the next. The Sadducees illustrate this. The resurrection is a truth especially precious to those who are poor and those who are hopeless. It is precious to those who long for heaven enough that earth holds no sway over them.

This means something to me. I didn’t grow up with parents who had any plan for me. I had to figure out what I was supposed to be doing with my life on my own, because they were both too busy doing their own things. This is true even to this day. After I became a Christian, there were many things that I wanted to achieve in this life. But for a variety of reasons, those most of those things never happened. I wanted to do great things for God, like getting married, having a family, getting a PhD and teaching computer science in a secular university. But things that I had intended to do for God just didn’t happen the way I had hoped.

I often find myself thinking of Heaven, and having that eternal perspective on this life. One of the things that is the hardest to accept is that being a Christian makes many things I’d like to do a lot harder. It certainly didn’t open any doors at school, or now, at work. I’m glad my salvation doesn’t depend on achieving anything in particular. And I’m especially glad that my salvation doesn’t depend on what anyone thinks of me. I find it almost impossible in this culture to get any respect by doing the things that I think are really important.

I think if a person were really successful at what they tried to do, then it would be really hard for them to give up living and go to be with Jesus. That’s not a problem for me, though. If fact, if the resurrection were not true, then I wouldn’t be able to say that my life was a very good life, measuring success the way people do.

The resurrection teaches correct apologetics methodology

Did you know that Jesus provided the resurrection as evidence for those who were skeptical of his claims to be God stepping into history?

Here’s an article from Got Questions? on the “Sign of Jonah”, which appears in the gospels of Matthew and Luke.

It says:

The phrase “sign of Jonah” was used by Jesus as a typological metaphor for His future crucifixion, burial, and resurrection. Jesus answered with this expression when asked by the Pharisees for miraculous proof the He was indeed the Messiah. The Pharisees remained unconvinced of Jesus’ claims about Himself, despite His having just cured a demon-possessed man who was both blind and mute. Shortly after the Pharisees accused Jesus of driving out demons by the power of Satan, they said to Him, “Teacher, we want to see a sign from you.” He answered, “A wicked and adulterous generation asks for a sign! But none will be given it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth. The men of Nineveh will stand up at the judgment with this generation and condemn it; for they repented at the preaching of Jonah, and now something greater than Jonah is here” (Matthew 12:38–41).

To fully appreciate the answer that Jesus gave, we must go to the Old Testament book of Jonah. In its first chapter, we read that God commanded the prophet Jonah to go to the city of Nineveh and warn its people that He was going to destroy it for its wickedness. Jonah disobediently ran from the Lord and headed for the city of Tarshish by boat. The Lord then sent a severe storm that caused the crew of the ship to fear for their lives. Jonah was soon thrown overboard and swallowed by a great fish where he remained for “three days and three nights” (Jonah 1:15–17). After the three-day period, the Lord caused the great fish to vomit Jonah out onto dry land (Jonah 2:10).

It is this three days that Jesus was referring to when He spoke of the sign of Jonah.

I often bring up the Sign of Jonah when I am dealing with Christians who don’t want to learn how to explain their faith to non-Christians persuasively. I’m glad that story is in there!

The resurrection is a very important part of the life of the Christian. I argued in this post that it makes a difference to your feelings about your own life, and it makes a difference to your case-making with non-Christians.

Four ways that the progress of experimental science conflicts with atheism

Christianity and the progress of science
Christianity and the progress of science

When people ask me whether the progress of science is more compatible with theism or atheism, I offer the following four basic pieces of scientific evidence that are more compatible with theism than atheism.

Here are the four pieces of evidence best explained by a Creator/Designer:

  1. the kalam argument from the origin of the universe
  2. the cosmic fine-tuning (habitability) argument
  3. the biological information in the first replicator (origin of life)
  4. the sudden origin of all of the different body plans in the fossil record (Cambrian explosion)

And I point to specific examples of recent discoveries that confirm those four arguments. Here are just a few of them:

  1. An explanation of 3 of the 6 experimental evidences for the Big Bang cosmology (From an article from Caltech)
  2. Examples of cosmic fine-tuning to allow the existence of conscious, embodied life (From the New Scientist)
  3. Evidence that functional protein sequences are beyond the reach of chance, (from Doug Axe’s JMB article)
  4. Evidence showing that Ediacaran fauna are not precursors to the Cambrian fossils, (from the journal Nature)

Atheists will typically reply to the recent scientific discoveries that overturned their speculations like this:

  1. Maybe the Big Bang cosmology will be overturned by the Big Crunch/Bounce so that the universe is eternal and has no cause
  2. Maybe there is a multiverse: an infinite number of unobservable, untestable universes which makes our finely-tuned one more probable
  3. Maybe the origin of life could be the result of chance and natural processes
  4. Maybe we will find a seamless chain of fossils that explain how the Cambrian explosion occurred slowly, over a long period time

Ever heard any of these responses?

Below I list some resources to help you to respond to the four responses of atheists to the experimental data.

1) The Big Crunch/Bounce has been disproved theoretically and experimentally.

Theoretically:

Nature 302, 505 – 506 (07 April 1983); doi:10.1038/302505a0

The impossibility of a bouncing universe

ALAN H. GUTH* & MARC SHER†

*Center for Theoretical Physics, Laboratory for Nuclear Science and Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA

†Department of Physics, University of California, Irvine, California 92717, USA

Petrosian1 has recently discussed the possibility that the restoration of symmetry at grand unification in a closed contracting Robertson–Walker universe could slow down and halt the contraction, causing the universe to bounce. He then went on to discuss the possibility that our universe has undergone a series of such bounces. We disagree with this analysis. One of us (M.S.) has already shown2 that if a contracting universe is dominated by radiation, then a bounce is impossible. We will show here two further results: (1) entropy considerations imply that the quantity S (defined in ref. 1 and below), which must decrease by ~1075 to allow the present Universe to bounce, can in fact decrease by no more than a factor of ~2; (2) if the true vacuum state has zero energy density, then a universe which is contracting in its low temperature phase can never complete a phase transition soon enough to cause a bounce.

Experimentally:

The universe is not only expanding, but that expansion appears to be speeding up. And as if that discovery alone weren’t strange enough, it implies that most of the energy in the cosmos is contained in empty space — a concept that Albert Einstein considered but discarded as his “biggest blunder.” The new findings have been recognized as 1998’s top scientific breakthrough by Science magazine.

[…]The flood of findings about the universe’s expansion rate is the result of about 10 years of study, said Saul Perlmutter, team leader of the Supernova Cosmology Project at Lawrence Berkeley National Laboratory.

Perlmutter and others found such a yardstick in a particular kind of exploding star known as a Type 1A supernova. Over the course of several years, the astronomers developed a model to predict how bright such a supernova would appear at any given distance. Astronomers recorded dozens of Type 1A supernovae and anxiously matched them up with redshifts to find out how much the universe’s expansion was slowing down.

To their surprise, the redshift readings indicated that the expansion rate for distant supernovae was lower than the expansion rate for closer supernovae, Perlmutter said. On the largest scale imaginable, the universe’s galaxies appear to be flying away from each other faster and faster as time goes on.

“What we have found is that there is a ‘dark force’ that permeates the universe and that has overcome the force of gravity,” said Nicholas Suntzeff of the Cerro Tololo Inter-American Observatory, who is the co-founder of another group called the High-z Supernova Search Team. “This result is so strange and unexpected that it perhaps is only believable because two independent international groups have found the same effect in their data.”

There has only been one creation of the universe, and the universe will never reverse its expansion, so that it could oscillate eternally. That view is popular, perhaps in part because many people watched videos of Carl Sagan speculating about it in public school classrooms, but all it was was idle naturalistic speculation, (Sagan was a naturalist, and held out hope that science would vindicate naturalism), and has been contradicted by good experimental science. You should be familiar with the 3 evidences for the Big Bang (redshift, light element abundances (helium/hydrogen) and the cosmic microwave background radiation. There are others, (radioactive element abundances, second law of thermodynamics, stellar lifecycle), but those are the big three. Point out how the experimental evidence for the Big Bang has piled up, making the problem even worse for the eternal-universe naturalists.

2) The multiverse has not been tested experimentally, it’s pure speculation.

Speculation:

Multiverse thinking or the belief in the existence of parallel universes is more philosophy or science fiction than science. ”Cosmology must seem odd to scientists in other fields”.

George Ellis, a well-known mathematician and cosmologist, who for instance has written a book with Stephen Hawking, is sceptical of the idea that our universe is just another universe among many others.

A few weeks ago, Ellis, professor emeritus of applied mathematics at the University of Cape Town, reviewed Brian Greene’s book The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos (Knopf/Allen Lane, 2011) in the journal Nature. He is not at all convinced that the multiverse hypothesis is credible: ”Greene is not presenting aspects of a known reality; he is telling of unproven theoretical possibilities.”

According to professor Ellis, there is no evidence of multiverses, they cannot be tested and they are not science.

Ellis is not the only multiverse sceptic in this universe. A few months ago, science writer John Horgan wrote a column in Scientific American, expressing his doubt in multiverses.

When you get into a debate, you must never ever let the other side get away with asserting something they have no evidence for. Call them on it – point out that they have no evidence, and then hammer them with evidence for your point. Pile up cases of fine-tuning on top of each other and continuously point out that they have no experimental evidence for their speculations. Point out that more evidence we get, the more cases of fine-tuning we find, and the tougher the problem gets for naturalists. There is no evidence for a multiverse, but there is evidence for fine-tuning. TONS OF IT.

3) Naturalistic theories for the origin of life have two problems: can’t make the amino acids in an oxydized atmosphere and can’t make protein and DNA sequences by chance in the time available.

Estimating the prevalence of protein sequences adopting functional enzyme folds.

Axe DD.

Proteins employ a wide variety of folds to perform their biological functions. How are these folds first acquired? An important step toward answering this is to obtain an estimate of the overall prevalence of sequences adopting functional folds.

[…]Starting with a weakly functional sequence carrying this signature, clusters of ten side-chains within the fold are replaced randomly, within the boundaries of the signature, and tested for function. The prevalence of low-level function in four such experiments indicates that roughly one in 10(64) signature-consistent sequences forms a working domain. Combined with the estimated prevalence of plausible hydropathic patterns (for any fold) and of relevant folds for particular functions, this implies the overall prevalence of sequences performing a specific function by any domain-sized fold may be as low as 1 in 10(77), adding to the body of evidence that functional folds require highly extraordinary sequences.

So atheists are in double jeopardy here. They don’t have a way to build the Scrabble letters needed for life, and they don’t have a way to form the Scrabble letters into meaningful words and sentences. Point out that the more research we do, the tougher the problem gets to solve for naturalists, and the more it looks like an effect of intelligence. Write out the calculations for them.

4) The best candidate to explain the sudden origin of the Cambrian era fossils was the Ediacaran fauna, but those are now recognized as not being precursors to the Cambrian fossils.

Science Daily reports on a paper from the peer-reviewed journal Science:

Evidence of the single-celled ancestors of animals, dating from the interval in Earth’s history just before multicellular animals appeared, has been discovered in 570 million-year-old rocks from South China by researchers from the University of Bristol, the Swedish Museum of Natural History, the Paul Scherrer Institut and the Chinese Academy of Geological Sciences.

[…]This X-ray microscopy revealed that the fossils had features that multicellular embryos do not, and this led the researchers to the conclusion that the fossils were neither animals nor embryos but rather the reproductive spore bodies of single-celled ancestors of animals.

Professor Philip Donoghue said: “We were very surprised by our results — we’ve been convinced for so long that these fossils represented the embryos of the earliest animals — much of what has been written about the fossils for the last ten years is flat wrong. Our colleagues are not going to like the result.”

Professor Stefan Bengtson said: “These fossils force us to rethink our ideas of how animals learned to make large bodies out of cells.”

The trend is that there is no evolutionary explanation for the body plans that emerged in the Cambrian era. If you want to make the claim that “evolution did it”, then you have to produce the data today. Not speculations about the future. The data we have today says no to naturalism. The only way to affirm naturalistic explanations for the evidence we have is by faith. But rational people know that we need to minimize our leaps of faith, and go with the simplest and most reasonable explanation – an intelligence is the best explanation responsible for rapid generation of biological information.

Conclusion

I do think it’s important for Christians to focus more on scientific apologetics and to focus their academic careers in scientific fields. So often I look at Christian blogs, and I see way too much G. K. Chesterton, Francis Chan and other untestable, ineffective jibber-jabber. We need to bring the hard science, and stop making excuses about not being able to understand it because it’s too hard. It’s not too hard. Everyone can understand Lee Strobel’s “The Case for a Creator“. That’s more than enough for the average Christian on science apologetics. We all have to do our best to learn what works. You don’t want to be anti-science and pro-speculation like atheists are. I recommend reading Uncommon Descent and Evolution News every day for a start.
