What does science tell us about God?
– the discoveries of Copernicus made humans less significant in the universe
– the discoveries of Darwin should that humans are an accident
– but this all pre-modern science
– what do the latest findings of science say about God?
Evidence #1: the origin of the universe
– the steady state model supports atheism, but was disproved by the latest discoveries
– the oscillating model supports atheism, but was disproved by the latest discoveries
– the big bang model supports theism, and it is supported by multiple recent discoveries
– the quantum gravity model supports atheism, but it pure theory and has never been tested or confirmed by experiment and observation
Evidence #2: the fine-tuning of physical constants for life
– there are over 100 examples of constants that must be selected within a narrow range in order for the universe to support the minimal requirements for life
– example: mass density
– example: strong nuclear force (what he studies)
– example: carbon formation
Evidence #3: the fine-tuning of our planet for habitability
– the type of galaxy and our location in it
– our solar system and our star
– our planet
– our moon
It’s a good lecture explaining a couple of basic arguments for a cosmic Creator and Designer. If you add the origin of life and the Cambrian explosion (Stephen C. Meyer’s arguments), then you will be solid on the basic scientific arguments for a Creator and Designer of the universe.
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:
the kalam argument from the origin of the universe
the cosmic fine-tuning (habitability) argument
the biological information in the first replicator (origin of life)
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:

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.
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.
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.
The Babraham Institute, Structural Biology Unit, Babraham Research Campus, Cambridge CB2 4AT, UK. firstname.lastname@example.org
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.
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.
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.
The topic: What are the arguments that make belief in God reasonable or unreasonable?
First speech: arguments for reasonableness of belief in God
Second speech: respond to arguments against reasonableness of belief in God
Contingency argument: God – a transcendent, personal being – is the explanation of why a contingent universe exists.
Cosmological argument: God is the cause of the beginning of the universe, which is attested by physics and cosmology.
Applicability of mathematics to nature: God is the best explanation for the applicability of mathematics to nature.
Fine-tuning argument: God is the best explanation of the fine-tuning of the universe to permit life.
Intentionality of conscious states: God is the best explanation of the intentionality of our mental states.
The moral argument: God is the best explanation for the existence of objective moral values and duties.
The resurrection of Jesus: God is the best explanation for the core of historical facts accepted by most ancient historians across the ideological spectrum.
Religious experience: God is the best explanation of our immediate experience and knowledge of his existence.
Dr. Rosenberg’s opening speech
First argument: The fallacy of ad hominem
I don’t know whether to laugh or to cry
Dr. Craig has said all of that before in other debates
You didn’t need to come out on this cold night
Craig’s arguments have all been refuted
Dr. Craig just doesn’t listen
Dr. Craig is not interested in getting at the truth
Dr. Craig is just interested in scoring debate points
The adversarial system is the wrong approach to decide truth
Dr. Craig is very confident about his take of physics
Second argument: The fallacy of arguing from authority
95% of members of the NAS are atheists
Therefore Dr. Craig cannot use science
Third argument: Effects don’t require causes
I am going to pretend that Craig said that “every effect requires a cause”
Quantum mechanics shows that some effects occur without causes
A particle of uranium (which is not nothing, it is something) decays without a cause
This uncaused effect is the same as the universe coming into being out of nothing uncaused
Therefore the principle of sufficient reason is false
Fourth argument: Silicon-based life and the multiverse
If these constants had been different, maybe we would have other kinds of intelligent life, like silicon-based life
Carbon-based life is not the only kind of life, maybe you can have other kinds of life, none of which have been observed
There could be different kinds of life in other areas of the universe that we can’t see
There are things we can’t see that disprove the current physics that we can see
Quantum foam is evidence that a multiverse exists
The multiverse would solve the problem of fine-tuning
Fifth argument: The Euthyphro dilemma
The moral argument is refuted by Euthyphro dilemma
Dr. Craig is such a moron that he has never heard of the Euthyphro dilemma ever before
This is found in the first and simplest of Plato’s dialogs
Why is Dr. Craig so stupid that he has not read this simple dialog ever before?
Evolution explains why humans evolve arbitrary customs and conventions that vary by time and place
Alternative moral theories: utilitarianism, social contract, etc. that don’t require God
Sixth argument: Mormonism undermines Dr. Craig’s three minimal facts about Jesus
Why is Dr. Craig so stupid and ignorant to persist in pushing such an ignorant, stupid argument?
Mormonism is a silly religion that is not historically well founded
Therefore, Jesus was not buried
Islam is a silly religion that is not historically grounded
Therefore, the tomb was not found empty
Scientology is a silly religion that is not historically grounded
Therefore, the eyewitnesses didn’t have post-mortem appearances
Eyewitness testimony is unreliable in some cases
Therefore, eyewitness testimony was unreliable in this case
Apparitions of Mary are bizarre
Therefore, the majority of historians are wrong to think that the disciples saw post-mortem appearances
Seventh argument: Deductive problem of evil
Evil and suffering are logically incompatible with an all good, all powerful God
Eight argument: God is not just to allow evil and suffering
God cannot make the evils of this life right in the afterlife
Dr. Craig’s first rebuttal
Dr. Rosenberg sketched the deductive argument from evil.
Dr. Rosenberg presupposes naturalism. Naturalism is a false theory of knowledge:
1. It’s too restrictive: There are truths that cannot be proved by natural science.
2. It’s self-refuting: no scientific proof for naturalism exists.
That’s why epistemological naturalism is considered false by most philosophers of science.
But more importantly than that: Epistemological naturalism does not imply metaphysical naturalism. (E.g. – W. Quine)
Dr. Rosenberg has to present arguments in favor of (metaphysical) naturalism, not just assume that (metaphysical) naturalism is true.
Dr. Craig presented eight arguments against metaphysical naturalism taken from Rosenberg’s own book:
1. The argument from the intentionality (aboutness) of mental states implies non-physical minds (dualism), which is incompatible with naturalism
2. The existence of meaning in language is incompatible with naturalism, Rosenberg even says that all the sentences in his own book are meaningless
3. The existence of truth is incompatible with naturalism
4. The argument from moral praise and blame is incompatible with naturalism
5. Libertarian freedom (free will) is incompatible with naturalism
6. Purpose is incompatible with naturalism
7. The enduring concept of self is incompatible with naturalism
8. The experience of first-person subjectivity (“I”) is incompatible with naturalism
Metaphysical naturalism is false: it is irrational and it contradicts our experience of ourselves.
And epistemological naturalism is compatible with theism.
Rebutting Dr. Rosenberg’s responses:
1. Contingency: no response
2. Cosmological: he mis-states the first premise to say every effect… when it is whatever begins to exist…, the origin of the universe was not from a vacuum, virtual particles come from a vacuum not nothing, there are interpretations of QM that are compatible with determinism. Rosenberg has to believe that the entire universe popped into being from non-being.
3. Mathematics: no response
4. Fine-tuning: the multiverse is refuted by empirical observations of the universe. Without fine-tuning, it’s not that we still have silicon to make life out of. It’s that we lose basic minimal things like chemical diversity, matter, stars, planets, etc. No life of any kind, not just no carbon-based life.
5. Intentionality: no response.
6. Moral argument: the answer to the dilemma is that you split the dilemma: God is the standard of good, and the commands flow from his unchanging moral nature. The commands are not arbitrary, and the standard is not external to God. Dr. Rosenberg is a nihilist and he cannot ground good and evil on his nihilistic view.
7. Resurrection: The Gospels are early eyewitness testimony. Mormonism and Islam have nothing to do with the minimal set of historical facts about Jesus agreed to by the majority of ancient historians across the ideological spectrum, general statements against eyewitnesses do not refute the specific eyewitness testimony in this case.
8. Religious experience: No response.
Dr. Rosenberg’s first rebuttal
I wrote a book and you should buy it, because it got me invited to this debate. Let me repeat the title a few times for you. Please buy it.
Dr. Craig is right, there are multiple interpretations of QM, not just the one I presented, including deterministic ones.
All the disturbing implications of naturalism that Dr. Craig stated follow from metaphysical naturalism, and metaphysical naturalism is true. (Note: he equates science with metaphysical naturalism)
Science proves that metaphysical naturalism is true, but I won’t say what specific scientific tests prove my philosophical assumption of metaphysical naturalism.
I’ll pretend that the Big Bang (science) doesn’t disprove naturalism, like Dr. Craig said. Again. (covers ears) La la la, there is no Big Bang.
We didn’t come here to debate epistemological naturalism and metaphysical naturalism.
Let me explain the problem of intentionality since I’m so smart and no one knows what it means.
There are many answers to this problem of intentionality.
My answer is that most scientists are naturalists, therefore naturalism is true, regardless of the argument from intentionality of mental states.
That’s how I would respond to one of the eight problems with naturalism that Dr. Craig raised. I won’t answer the other seven problems.
It is an argument from ignorance to argue that the applicability of mathematics to the universe requires a designer, because there are non-Euclidean geometries. Craig’s argument, which he gets from people like respected physicists like Eugene Wigner, is bizarre. It is bizarre, therefore I refute Eugene Wigner and all the other scholars who make that argument. It is bizarre! Bizarre!
Deductive problem of evil: there is no response to this argument, certainly not Alvin Plantinga’s free will defense. The deductive argument from evil has not been entirely abandoned at all! It’s not like arch-atheist J.L. Mackie himself admits that the deductive problem of evil doesn’t lead to a logical inconsistency between evil and God.
Dr. Craig has to tell me why God allows evil or God doesn’t exist.
It is offensive that Dr. Craig cannot tell me why God allows every evil and suffering that occurs.
He literally said this: “I will become a Christian if Dr. Craig can tell me why God allowed EVERY EVIL THAT OCCURRED IN THE LAST 3.5 BILLION YEARS”
Dr. Craig’s second rebuttal
We are not in a position to know why God allows specific instances of evil and suffering.
God cannot force people to freely do anything – freedom is not compatible with determinism. Freedom is a good, but freedom opens up the possibility of moral evil. You cannot have the good of free will without allowing people to choose to do morally evil things.
God can permit evil and suffering in order to bring more people into a relationship with him.
The atheist has to show that God could allow less evil and achieve more knowledge of God in order to say there is too much evil.
The purpose of life is not happiness, but knowledge of God.
Dr. Craig quotes agnostic Paul Draper (Purdue) and Peter Van Inwagen (Notre Dame) to state that the deductive problem of evil is dead because of free will and morally sufficient reasons for permitting evil.
1. Contingency: no response.
2. Cosmological: QM does not apply, because the universe came from nothing, not a vacuum, and QM only works in a vacuum.
3. Mathematics: He mentions alternatives like non-Euclidean geometry, but we have to explain the structure of THIS universe.
4. Fine-tuning: ???
5. Intentional states: intentional mental states proves that minds exist, which fits with theism better than it fits with atheism.
6. Moral argument: You need God to ground morality, and Dr. Rosenberg believes in morality. He needs God to ground objective moral values and duties.
7. Historical argument: He has to respond to the minimal facts supported by the consensus of ancient historians across the ideological spectrum.
8. The problems of naturalism: He says that you can’t have science without naturalism, but you can have science with EPISTEMOLOGICAL NATURALISM, and theists accept science and methodological naturalism. We don’t accept METAPHYSCIAL NATURALISM because of the eight problems Craig presented, like intentionality, first-person, persistence of self, etc. You can believe in both science and theism, by embracing epistemological naturalism, while rejecting methaphysical naturalism.
Dr. Rosenberg’s second rebuttal
Dr. Craig hasn’t answered many of my points, I won’t say which ones though.
Debates don’t work as a way of deciding what’s true, so we should overturn the entire criminal justice system.
The principle of sufficient reason is false because it is disconfirmed by quantum mechanics. And quantum mechanics (vacuum and virtual particles that exist for a short time) is similar to the origin of the universe (nothing and entire universe and 14 billion years).
We know that alpha particles come into being without cause all the time from a quantum vacuum for a tiny sub-second duration before going out of existence, so we can say that the entire physical universe came into being for 14 billion years from absolute nothing which is not a quantum vacuum.
Peter Van Inwagen is the best metaphysician working today, and he says that my deductive argument from evil is not decisive, it’s not a successful argument. (Why is he undermining his own problem of evil argument????!)
Dr. Craig invoked Plantinga’s free will defense to the deductive POE. Freedom allows us to do evil. God could have given us free will without evil and suffering. I won’t show how, but I’ll just assert it, because debates are such a bad forum for supplying evidence for my speculative assertions.
If you answer the question 3 + 5 as being 8, then you don’t have free will – you are biologically determined if you answer 8, because everyone answers 8, and that means everyone is biologically determined with no free will.
Why can’t God give us free will and then prevent us from making a free choice?
No scholars date the gospels earlier than 60-70 AD, especially not atheists like James Crossley who dates Mark to 40 AD. Therefore Jesus’ burial isn’t historical, like the majority of scholars across the broad spectrum of scholarship agree it is.
The original New Testament documents were written in Aramaic.
All New Testament scholars are orthodox Christians, like atheist Robert Funk for example.
Dr. Craig’s concluding speech
In order to sustain the deductive argument from evil, Dr. Rosenberg must show that God could create a world of free creatures with less evil.
Principle of Sufficient Reason: not using the general principle of sufficient reason, but a more modest version of this states that contingent things should have an explanation for their existence. And we know that the universe is a contingent.
The New Testament was not written in Aramaic, they were written in Greek. Dr. Rosenberg is wrong there too.
(Dr. Craig spends the rest of his concluding speech giving his testimony and urging people to investigate the New testament).
Dr. Rosenberg’s concluding speech
Some long-dead French guy named Laplace said that he has no need of that (God) hypothesis. He did not know about any of Dr. Craig’s arguments made in this debate tonight when he said that, though.
There is no need to explain how the universe began or how the universe is finely-tuned if you just assume metaphysical naturalism on faith.
The Easter Bunny, therefore atheism.
Most scientists are atheists, therefore atheism.
You can do a lot of science without God, just don’t look at the origin of the universe, the fine-tuning of the universe, or the other parts of science that Craig mentioned, as well as the origin of life, the Cambrian explosion, the habitability argument, and so on.
You can be a Christian, but good Christians should not use arguments and evidence.
Good Christians should be irrational and ignorant. Bad Christians look for arguments and evidence from science and history.
Good Christians should embrace the absurd. Bad Christians want to search for truth and use logic and evidence.
The MIT physicist says that the fine-tuning is real, and is best explained by positing the existence of an infinite number of universes that are not fine-tuned – the so-called multiverse.
While challenging the Platonic dream of theoretical physicists, the multiverse idea does explain one aspect of our universe that has unsettled some scientists for years: according to various calculations, if the values of some of the fundamental parameters of our universe were a little larger or a little smaller, life could not have arisen. For example, if the nuclear force were a few percentage points stronger than it actually is, then all the hydrogen atoms in the infant universe would have fused with other hydrogen atoms to make helium, and there would be no hydrogen left. No hydrogen means no water. Although we are far from certain about what conditions are necessary for life, most biologists believe that water is necessary. On the other hand, if the nuclear force were substantially weaker than what it actually is, then the complex atoms needed for biology could not hold together. As another example, if the relationship between the strengths of the gravitational force and the electromagnetic force were not close to what it is, then the cosmos would not harbor any stars that explode and spew out life-supporting chemical elements into space or any other stars that form planets. Both kinds of stars are required for the emergence of life. The strengths of the basic forces and certain other fundamental parameters in our universe appear to be “fine-tuned” to allow the existence of life. The recognition of this fine-tuning led British physicist Brandon Carter to articulate what he called the anthropic principle, which states that the universe must have the parameters it does because we are here to observe it. Actually, the word anthropic, from the Greek for “man,” is a misnomer: if these fundamental parameters were much different from what they are, it is not only human beings who would not exist. No life of any kind would exist.
If such conclusions are correct, the great question, of course, is why these fundamental parameters happen to lie within the range needed for life. Does the universe care about life? Intelligent design is one answer. Indeed, a fair number of theologians, philosophers, and even some scientists have used fine-tuning and the anthropic principle as evidence of the existence of God. For example, at the 2011 Christian Scholars’ Conference at Pepperdine University, Francis Collins, a leading geneticist and director of the National Institutes of Health, said, “To get our universe, with all of its potential for complexities or any kind of potential for any kind of life-form, everything has to be precisely defined on this knife edge of improbability…. [Y]ou have to see the hands of a creator who set the parameters to be just so because the creator was interested in something a little more complicated than random particles.”
Intelligent design, however, is an answer to fine-tuning that does not appeal to most scientists. The multiverse offers another explanation. If there are countless different universes with different properties—for example, some with nuclear forces much stronger than in our universe and some with nuclear forces much weaker—then some of those universes will allow the emergence of life and some will not. Some of those universes will be dead, lifeless hulks of matter and energy, and others will permit the emergence of cells, plants and animals, minds. From the huge range of possible universes predicted by the theories, the fraction of universes with life is undoubtedly small. But that doesn’t matter. We live in one of the universes that permits life because otherwise we wouldn’t be here to ask the question.
I thought I was going to have to go outside this article to refute the multiverse, but Lightman is honest enough to refute it himself:
The… conjecture that there are many other worlds… [T]here is no way they can prove this conjecture. That same uncertainty disturbs many physicists who are adjusting to the idea of the multiverse. Not only must we accept that basic properties of our universe are accidental and uncalculable. In addition, we must believe in the existence of many other universes. But we have no conceivable way of observing these other universes and cannot prove their existence. Thus, to explain what we see in the world and in our mental deductions, we must believe in what we cannot prove.
Sound familiar? Theologians are accustomed to taking some beliefs on faith. Scientists are not. All we can do is hope that the same theories that predict the multiverse also produce many other predictions that we can test here in our own universe. But the other universes themselves will almost certainly remain a conjecture.
The multiverse is not pure nonsense, it is theoretically possible. The problem is that the multiverse generator itself would require fine-tuning, so the multiverse doesn’t get rid of the problem. And, as Lightman indicates, we have no independent experimental evidence for the existence of the multiverse in any case. Atheists just have to take it on faith, and hope that their speculations will be proved right. Meanwhile, the fine-tuning is just as easily explained by postulating God, and we have independent evidence for God’s existence, like the the origin of biological information, the sudden appearance of animal body plans, the argument from consciousness, and so on. Even if the naturalists could explain the fine-tuning, they would still have a lot of explaining to do. Theism (intelligent causation) is the simplest explanation for all of the things we learn from the progress of science.
We need to be frank about atheists and their objections to the progress of science. Within the last 100 years, we have discovered that the physical universe came into being out of nothing 15 billion years ago, and we have discovered that this one universe is fine-tuned for intelligent life. I don’t think it’s like that the last 100 years of scientific progress on the origins question are going to be overturned so that science once again affirms what atheists believe about the universe. Things are going the wrong way for atheists – at least with respect to science.
See it in action
To see these arguments examined in a debate with a famous atheist, simply watch the debate between William Lane Craig and Christopher Hitchens, and judge which debater is willing to form his beliefs on scientific progress, and which debater is forming his beliefs against the science we have today, and hoping that the good science we have today based on experiments will be overturned by speculative theories at some point in the future. When you watch that debate, it becomes very clear that Christian theists are interested in conforming their beliefs to science, and atheists are very interested in speculating against what science has shown in order to maintain their current pre-scientific view. That’s not what rational people ought to do when confronted with evidence.
