Four reasons to think that atheism is inconsistent with scientific progress

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:

  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 Physics Forums)
  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:

The impossibility of a bouncing universe

ALAN H. GUTH* & MARC SHER†

†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.

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 A. W. Tozer, 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.

Why did Dan Barker leave Christianity for atheism?

A conflict of worldviews
A conflict of worldviews

Unbelievable’s  radio show featured a discussion with former Christian Dan Barker, the founder and co-President of the Freedom From Religion Foundation.

The MP3 file is here. (60 minutes)

I thought that I would make some general comments about why I think that many people leave the Christian faith, and what you should be careful of in order to avoid following in Dan Barker’s footsteps, specifically.

Basically, there are four major reasons why people leave Christianity.

  1. They want to do something immoral with impunity. This type of person wants to do something immoral that is forbidden by Christianity, like pre-marital sex or getting drunk in clubs with friends. They dump Christianity in order to have freedom to seek happiness in this life.
  2. They want to make decisions based on their emotions, rather than wisdom. This type of person thinks that God’s job is to save them when they act irresponsibly. When God disappoints them by not make their recklessness “work out”, they leave the faith.
  3. They want to be loved by people, not by God. This type of person thinks that Christianity is a tool that they can use to become popular. When they first try to articulate the gospel in public, they find that people don’t like them as much, and they feel bad about offending people with exclusive truth claims that they cannot back up using logic and evidence. So, they water down Christianity to get along with non-Christians. Finally, they jettison Christianity completely. This happens to a lot of young Christians the moment they hit college / university.
  4. They don’t want to learn to defend their faith. This type of person is asked questions by skeptics that they cannot answer. Usually this happens when people go to university after growing up in the shelter of the Church. The questions and peer pressure make them feel stupid. Rather than investigate Christianity to see if it’s true, they drop it, so they can be thought of as part of the “smart” crowd.

Now listen to the discussion and see if you can identify some of these factors from Barker’s own carefully-prepared words. He is trying very hard to make himself look honest and moderate, because he wants Christians to be sympathetic with his story and his motives for leaving Christianity. But I think that there is enough in his statements to construct a different hypothesis of why he left Christianity.

I’ve grouped the data by risk factor. Some of this is my interpretation of his real motivations, based on my experience dealing with former-Christians.

Non-rational, emotional approach to Christianity

  • he was raised in a devout Christian family where he probably wouldn’t have faced skeptical questions
  • he converted to Christianity at age 15 as a result of a religious experience, not a serious investigation
  • his idea of God was probably idealized and uninformed, e.g. – a loving God who wants us to be happy
  • he wandered around from church to church preaching, with no fixed address or source of income
  • he earned money by collecting “love offerings” from churches where he performed his music
  • he wrote Christian songs and Christian musicals, but nothing substantive on apologetics and theology
  • he worked in three churches known for being anti-intellectual and fundamentalist
  • there’s no evidence that of any deep study of philosophy, science and history during this time

Desire to gain acceptance from non-Christians

  • he began to notice that some people were uncomfortable with sin and Hell
  • he began to avoid preaching about sin and Hell in order to make these people comfortable
  • he watered-down the gospel to focus on helping people to be happy in this life
  • his manic approach to Christian ministry was challenged by the “real life” needs of his growing family
  • he met liberal pastors while performing his music in their churches
  • he found it difficult to disagree with them because they seemed to be “good” people
  • he watered down his message further in order to appeal to people across the theological spectrum

Ignorance of Christian apologetics

  • he began to think that if there are many different views of religion, then no view can be correct
  • he was not intellectually capable of using logic and evidence to test these competing claims to see which was true
  • he decided to instead re-interpret Christian truth claims as non-rational opinions, so they could all be “valid”
  • he became a theological liberal, abandoning theism for an impersonal “ground of being”
  • he embraced religious pluralism, the view that all religions are non-rational and make no testable truth claims
  • he began to see God as a “metaphor” whose purpose is to make people have a sense of meaning and purpose
  • he jettisoned God completely and focused more on helping people find meaning and morality apart from God
  • seems to think that religion is about having a “great life”, and felt that you can have a “great life” without religion
  • seems to think that religion is about being “good”, and felt that you can be “good” without religion
  • religion makes people feel bad by telling them what to do instead of letting them do anything they want
  • religion makes people feel bad by telling them what is true, instead of letting them believe whatever they want
  • religion makes people feel bad by telling them that God will hold them accountable for their beliefs and actions

So what do I think happened?

Barker was generating an income from donations from churches where he entertained them. Gradually, his family grew to the point where conservative churches were not enough to support him. He had to change his message to appeal to liberal churches in order to cast a wider net.

He seems to have thought that Christianity is about having his needs met and being liked by others. I think he wanted to feel good and to make people feel good with his preaching and singing. But Christianity is not a feel-good religion. It’s not a tool to make people like you. He seems to have become aware that the exclusive claims of Christianity made other people feel offended, so he cut them out. Christian apologists learn how to provide evidence for claims that non-Christians find offensive or hard to believe, but Dan hadn’t studied philosophy, science or history so he couldn’t defend it. It’s hard to speak unpopular truths when you have nothing to back it up except your music composing. Eventually, Dan just quit making the truth claims entirely.

I also think money was a factor. It seems to me that it would have hurt his career and reduced his invitations from liberal churches if he had kept up teaching biblical Christianity. In order to appeal to a wider audience, (like many Christian singers do – e.g. – Amy Grant, Jars of Clay, etc.), he would have felt pressured to water down the unpleasant parts of his preaching and singing. Lacking apologetics skill, he instead abandoned his message. He needed to account for his family’s needs and “real life”, and exclusive truth claims and Hell-talk would have reduced his ability to do that. It seems to me that he should have scaled back his extreme schedule of preaching and singing, and instead gotten a steady job so that he could afford “real life” and a family without being pressured into altering his message. The Christian life requires a certain amount of wisdom that Dan did not have.

Life isn’t a fairy tale. God isn’t there to reward risky behavior. We need to be more shrewd about financial matters so that we have the ability to not care about what people think of us. Look at this blog. I work all day as a senior software engineer with two degrees in computer science, so that I don’t have to rely on donations. Additionally, I save most of what I make in case a tragedy strikes. Since I am financially secure, I can say what I think, and disregard anyone who wants me to change my message because they are offended. Becoming a Christian isn’t a license to behave irrationally and immaturely with money. For some people, (like William Lane Craig), stepping out in faith works. But if it doesn’t work, it’s better to retreat and re-trench, rather than to compromise your message for money.

I actually met someone like Dan Barker recently. She grew up in an anti-intellectual hippy Christian home. Her mother came from a good family, and decided on a whim to marry a non-Christian. Like Barker, the family exalted feelings and irrational expectations of miracles from God for “fearless” acts. She got herself into trouble with alcohol and promiscuity in her 20s, by making emotional decisions and mixing with the wrong crowd. Her way of fixing this was to fly off on a one-year missions trip, wrecking her resume and finances. Now, she is in her late 30s, unmarried, and literally blaming Jesus for putting too many demands on her that she doesn’t have time for, e.g – morning quiet time. This causes her to feel guilty, and make her want to reject Christianity. She had no intellectual conception of basic core doctrines like God’s existence or Jesus’ resurrection, which might have acted as a bulwark against her emotions. When I explained to her how I had structured my education and career so that I could have an influence without testing God, she seemed bored and said that I was too “fearful”.

This is apparently widespread, especially among anti-intellectual denominations. Another ex-Pentecostal atheist woman I heard about from people who knew her when she was young decided to drop out of college to travel around North America doing pro-life work. When she found herself penniless, unmarried and without children in her mid-30s, she decided to have a baby out of wedlock. The government will pay for it, she said. Rather than trying to justify this decision as a Christian, she blamed God for not making her madness “work out”. She is now an atheist, because God did not reward her decision to live “fearlessly” for him with a husband and children. It was all God’s fault. There is a whole subculture within Christianity, where the pursuit of fun and thrills can be masked with pious language, and all talk of prudence and restraint is seen as cowardice and lack of faith.

The Christian life requires a certain level of intelligence, a certain level of practical wisdom, and a certain level of self-control and discipline. Make sure that you don’t walk away from God because of your own bad choices.

Christian philosopher (Craig) vs atheist scientist (Atkins) debate: Does God Exist?

I found a video of a debate from the Reasonable Faith speaking tour in the UK, between Christian philosopher Dr. William Lane Craig and atheist chemist Dr. Peter Atkins.

Here is the video:

This is a must-see debate. It was extremely fun to watch, and I have a snarky summary of the opening speeches below.

Details:

On Wednesday 26th October 2011 William Lane Craig debated Peter Atkins on the topic: Does God Exist? This debate took place at the University of Manchester  as part of the UK Reasonable Faith Tour with William Lane Craig. The debate was chaired by Christopher Whitehead, Head of Chemistry School at the University. Post-debate discussion was moderated by Peter S Williams, Philosopher in Residence at the Damaris Trust, UK.

Dr. William Lane Craig:

William Lane Craig (born August 23, 1949) is an American analytic philosopher, philosophical theologian, and Christian apologist. He is known for his work on the philosophy of time and the philosophy of religion, specifically the existence of God and the defense of Christian theism. He has authored or edited over 30 books including The Kalam Cosmological Argument (1979), Theism, Atheism and Big Bang Cosmology(co-authored with Quentin Smith, 1993), Time and Eternity: Exploring God’s Relationship to Time (2001), and Einstein, Relativity and Absolute Simultaneity (co-edited with Quentin Smith, 2007).

Craig received a Bachelor of Arts degree in communications from Wheaton College, Illinois, in 1971 and two summa cum laudemaster’s degrees from Trinity Evangelical Divinity School in Deerfield, Illinois, in 1975, in philosophy of religion and ecclesiastical history. He earned a Ph.D. in philosophy under John Hick at the University of Birmingham, England in 1977 and a Th.D. underWolfhart Pannenberg at the University of Munich in 1984.

Dr. Peter Atkins:

Peter William Atkins (born 10 August 1940) is a British chemist and former Professor of Chemistry at the University of Oxford and a Fellow of Lincoln College. He is a prolific writer of popular chemistry textbooks, including Physical ChemistryInorganic Chemistry, and Molecular Quantum Mechanics. Atkins is also the author of a number of science books for the general public, including Atkins’ Molecules and Galileo’s Finger: The Ten Great Ideas of Science.

Atkins studied chemistry at the University of Leicester, obtaining a bachelor’s degree in chemistry, and – in 1964 – a PhD for research into electron spin resonance spectroscopy, and other aspects of theoretical chemistry. Atkins then took a postdoctoral position at the UCLA as aHarkness Fellow of the Commonwealth fund. He returned to Oxford in 1965 as fellow and tutor of Lincoln College, and lecturer in physical chemistry (later, professor of physical chemistry).

I am happy when debates like this come out. I have friends who are Christians who doubt the importance of apologetics in evangelism, because they don’t think that apologists can prove anything or win arguments. I have friends who are skeptical of using arguments that assume a 14-billion year old universe, because they think that the Big Bang is compatible with atheism (!). I have friends who think that philosophical arguments have no persuasive force. I have friends who think that nothing can be proven from history, beyond a reasonable doubt. I have co-workers who ask me whether anyone wins these debates. I think that this debate answers all of those questions.

This debate clearly shows why Christians should not shy away from studying science, philosophy and history. We will not discover anything that harms Christian theism by thinking logically and by looking at the evidence. To the contrary, it is the atheist who makes war on the progress of science, and who is forced to resist the clear experimental evidence, and to resort to baseless speculations and blind faith. If you want to see a good debate with an intelligent atheist, I recommend watching the debate between William Lane Craig and Peter Millican instead. But if you want to see a really, really overwhelming defeat for atheism, watch this debate. It is very clear at the end of this debate why Richard Dawkins refused to debate William Lane Craig at Oxford.

SUMMARY OF THE OPENING SPEECHES

I only had time to summarize the first two speeches. Keep in mind that Dr. Craig always shines in his rebuttals, and this debate is no different. So you’ll want to watch those rebuttals. Dr. Atkins literally says in this debate in his first rebuttal “There was nothing here originally. There is nothing here now. But it is an interesting form of nothing which seems to be something.” And the audience laughs nervously. This debate is like that. You will see a clear winner and clear loser in this debate. This fight is decided by knockout.

William Lane Craig opening speech:

1. the origin of the universe
2. the moral argument
3. the resurrection of Jesus

Peter Atkins opening speech:

1. Dr. Craig is stupid, lazy and evil:
– Dr. Craig’s arguments are old: from the 11th century! Old arguments can’t be true
– Dr. Craig is just asserting that “God did it” because he is lazy
– Dr. Craig feels pressured to agree with the theistic majority
– Dr. Craig needs a psychological crutch to comfort him
– Dr. Craig is fearful of death
– Dr. Craig is just wishing for an eternal life of bliss
– Dr. Craig is driven by his heart, and not by his head

2. Origin of the universe:
– Maybe the universe is eternal and has no beginning – we don’t know
– Maybe mommy universes can give birth to daughter universes
– It is naive to think that a cause is needed to cause the creation of the universe from nothing
– Science is just about to show how it is possible that something appears out of nothing without cause
– Some scientists have already begun to speculate about about how something can come into being out of nothing
– Maybe nothing is not really nothing, but it is actually something
– It would be admitting defeat to say that God created the universe out of nothing

3. Fine-Tuning:
– It could be the case that the fundamental constants are not variable
– It could be the case that the fine-tuning of the cosmic constants is a happy accident
– It could be the case that there are billions of billions of unobservable universes that are not fine tuned
– It could be the case that the cosmic constants in these billions and billions of unobservable universes are all random so that some are fine-tuned
– Anyone who infers that an intelligence is the best explanation of a finely-tuned set of life-permitting cosmic constants is lazy

4. Purpose:
– Philosophers and theologians are stupid
– I don’t think that there is purpose in the universe
– I think that the universe is more grand if there is no purpose, so there is no purpose

5. Miracles:
– I don’t think that miracles happen
– The resurrection is a fabrication
– It could be the case that Jesus didn’t exist
– It could be the case that Jesus wasn’t really crucified
– It could be the case that Jesus didn’t  really die after being crucified
– It could be the case that the disciples stole his body
– It could be the case that the women went to the wrong hole in the ground
– the gospels are political propaganda written long after the events they are reporting on

6. Theodicy:
– God has no morally sufficient reason for allowing humans to perform actions that result in suffering
– God has no morally sufficient reason for allowing nature to cause suffering

7. Morality:
–  customs and conventions emerges arbitrarily in different times and places based on an awareness of the consequences of actions, as well as various anecdotes and experiences
–  these customs and conventions are decided based on the goal for survival, in much the same way as politeness and manners emerge for decorum and to avoid offense
– it is childish to presume that there is an umpire God who decides moral values and duties

8. Religious believers are stupid, lazy and evil:
– the notion of God has arisen because people are stupid and want to be comforted
– there are no arguments or evidences for belief in God
– people who believe in God do not think, but instead take refuge in incomprehensible nonsense
