This lecture is special to me, because I bought a VHS tape of it just after I started working full-time, and watched it a million times. A lot of people come to their convictions about God’s existence because of parents or church or intuitions, but for me it’s all about the scientific evidence. This lecture changed my life. I wish more people taught their children about this evidence! This lecture was delivered at the University of California, Santa Barbara.

This slide summarizes the content of the lecture
Introduction:
At the beginning of the 20th century, people believed that the progress of science was pointing away from an intelligent Creator and Designer, and towards naturalism
A stream of new discoveries has shifted the support of science towards theism, and away from naturalism
Richard Dawkins, an atheist, says that nature only has the appearance of design, but that if you look closer, naturalistic mechanisms can account for the appearance of design
When deciding between design and apparent design (“designoid”), it matters whether you think there is an intelligence there to do the designing
Evidence #1: The Big Bang:
an eternal “steady state” universe is more compatible with naturalism, but a created universe is more compatible with a Creator
In 1929, Hubble used telescopes to observe that the light from distant galaxies was redshifted. The further away galaxies were, the faster they were moving away. Therefore, space is expanding in all directions, suggesting an explosive origin of the universe
In 1965, the discovery of the cosmic microwave background radiation matched a prediction of the Big Bang cosmology, and of the creation event
In 1992, the COBE space telescope allowed us to test four specific predictions of the Big Bang model, especially the predictions for light element abundances (hydrogen and helium), which matched the predictions of the creation model
Evidence #2: Simple mathematical structure of the physical laws
the simple mathematical structure of natural laws allows us to understand these laws, make discoveries, and engineer solutions to problems
early scientists saw the mathematical structure of the universe to mean that nature was designed by an intelligent to be understood
the fundamental equations of the laws of the universe can be easily written on one side of one sheet of paper
Eugene Wigner’s famous paper, “The Unreasonable Effectiveness of Mathematics in the Physical Sciences” makes the point that this simple structure is an unexpected gift that allows is to do science
Evidence #3: fine-tuning of the physical constants and quantities
in order for any kind of complex life to survive, we need stars that provide energy within specific ranges for long periods of time
in order for any kind of complex life to survive, we need planets with stable orbits that will not suffer from extreme temperature swings as it varies in distance from its star
in order for any kind of complex life to survive, we need stable atomic structure
in order for any kind of complex life to survive, we need to have chemical diversity and correct relative abundances of each element
organic life has minimum requirements: process energy, store information, replicate, and you can’t fulfill those functions if there is only one element, e.g. – hydrogen
the energy level from the photons from the sun have to match the energy levels of the different elements in order to drive the chemical bonding needed for life
These requirements for life of any imaginable type depend on the values of the constants and quantities. The constants and quantities cannot vary much from what they are, or the universe will lose the characteristics (above) that allow it to support complex life of any imaginable time
For example, ratio of strong force to electromagnetic force:
– if 2% larger, then no stable hydrogen, no long-lived stars, no compounds containing hydrogen, e.g. – water
– if 5% smaller, no stable stars, heavy hydrogen would be unstable, few elements other than hydrogen
Evidence #4: initial conditions for habitability
Universe: expansion rate of the universe must be fast enough to avoid a re-collapse, but slow enough to allow matter to clump together and form stars and planets for complex life to live on
Planet: right distance from the star to get the right climate
Planet: right mass to retain the right atmosphere
Evidence #5: origin of life and information theory
It’s possible to explain every process in an automobile engine using plain old naturalistic mechanisms – no supernatural explanation is necessary to understand the processes
But the existence of engine itself: engineering all the parts has to be explained by the work of an intelligence
Similarly, we can understand how living systems work, but the existence of the living systems requires an intelligence
Even the simplest living system has to perform minimal function: capture energy, store information and replicate
Living systems are composed of objects like proteins that are composed of sequences of components complex such that the order of the components gives the overall structure function
Developing the components for a simple living cell is very improbable – even given the large number of galaxies, stars and planets in the universe, it is unlikely that complex, embodied life would exist anywhere in the universe
Evidence #6: more initial conditions for habitability
Location within the galaxy: you need to be away from the center of the galaxy, because the explosions from dying stars, and excessive radiation will kill life
Location within the galaxy: you need to be close enough to the center in order catch the heavy elements you need for life from the explosions of other stars
Location within the galaxy: the best location is between two arms of a spiral galaxy, where you can get the heavy elements you need from dying stars, but without being hit with explosions and harmful radiation
Star mass: determines rate at which the sun burns, determines the energy level of photons that are used to drive chemical bonding reactions, determines the length of time the star will be stable
Star mass: star mass must be the correct value in order to allow liquid water on the planet’s surface, while still preserving stable orbit
I wish there was more curiosity about science in churches, and young Christians understood how critical science is for grounding the rationality of the Christian worldview. We need to be training up more scientists who think about the big questions, like Dr. Walter Bradley.
How do you present theism as a rational belief to a person who thinks that the progress of science has removed the need for God?
Canadian science writer Denyse O’Leary writes about the history of cosmology at Evolution News.
Excerpt:
What help has materialism been in understanding the universe’s beginnings?
Many in cosmology have never made any secret of their dislike of the Big Bang, the generally accepted start to our universe first suggested by Belgian priest Georges Lemaître (1894-1966).
On the face of it, that is odd. The theory accounts well enough for the evidence. Nothing ever completely accounts for all the evidence, of course, because evidence is always changing a bit. But the Big Bang has enabled accurate prediction.
In which case, its hostile reception might surprise you. British astronomer Fred Hoyle (1915-2001) gave the theory its name in one of his papers — as a joke. Another noted astronomer, Arthur Eddington (1882-1944), exclaimed in 1933, “I feel almost an indignation that anyone should believe in it — except myself.” Why? Because “The beginning seems to present insuperable difficulties unless we agree to look on it as frankly supernatural.”
One team of astrophysicists (1973) opined that it “involves a certain metaphysical aspect which may be either appealing or revolting.” Robert Jastrow (1925-2008), head of NASA’s Goddard Institute for Space Studies, initially remarked, “On both scientific and philosophical grounds, the concept of an eternal Universe seems more acceptable than the concept of a transient Universe that springs into being suddenly, and then fades slowly into darkness.” And Templeton Prize winner (2011) Martin Rees recalls his mentor Dennis Sciama’s dogged commitment to an eternal universe, no-Big Bang model:
For him, as for its inventors, it had a deep philosophical appeal — the universe existed, from everlasting to everlasting, in a uniquely self-consistent state. When conflicting evidence emerged, Sciama therefore sought a loophole (even an unlikely seeming one) rather as a defense lawyer clutches at any argument to rebut the prosecution case.
Evidence forced theorists to abandon their preferred eternal-universe model. From the mid 1940s, Hoyle attempted to disprove the theory he named. Until 1964, when his preferred theory, the Steady State, lost an evidence test.
Here is a quick summary of some of the experimental evidence that emerged in the last few decades that caused naturalists to abandon the eternal universe that they loved so much when they were younger.
The importance of having a narrative
Now I want to make a very, very important point about Christianity and the progress of science. And that point is that it is very important that Christians present the evidence in exactly the way that Denyse presented it in that article – in its historical context, featuring the conflict between naturalists and the experimental evidence.
All Christians should be familiar with the following basic pieces of evidence which fit the war between science and naturalism narrative:
The origin of the universe
The cosmic fine-tuning
The origin of life (biological information)
The sudden origin of the Cambrian phyla
The habitability/observability correlation
When you talk about these evidences as a Christian theist to non-Christians, you have to have cultivated a genuine interest in reconciling your beliefs with science. You have to accept that there are two books that reveal God’s character and attributes. The book of nature, and the book of Scripture. And you need to be flexible about getting these two books to fit together. The book of nature gives us natural theology (see Romans 1). It tells us that God is Creator and Designer. The book of Scripture tells us that God stepped into history as a man to save us by taking the punishment for our headlong rush away from God, which the Bible calls sin. Science is one way that humans can recover some of basic knowledge about God. Knowledge that is only possible because God created and designed the universe (and us) in such a way that we are capable of making discoveries, and that the universe is capable of being explored and understood.
It’s very important to present these five basic evidences to non-Christians in the historical context. And here is the story you must tell: “In the beginning, there was the naturalism, and the naturalism tried to argue from ignorance that God was not Creator and God was not Designer. And then came the science, and now people have to give up their naturalism in order to account for the science”. That’s the narrative you use when talking to non-Christians about science.
In the beginning was the naturalism:
In pre-scientific times, atheists maintained that the universe was eternal
In pre-scientific times, atheists maintained that a life-permitting universe was as likely as a life-prohibiting universe
In pre-scientific times, atheists maintained that the cell was a simple blob of Jello that could spontaneously emerge in some warm pond
In pre-scientific times, atheists maintained that the sudden origin of the Cambrian phyla would be explained by subsequent fossil discoveries
In pre-scientific times, atheists maintained that there was nothing special about our galaxy, solar system, planet or moon
But then science progressed by doing experiments and making observations:
Scientists discovered redshift and the cosmic microwave background radiation (evidence for a cosmic beginning) and more!
Scientists discovered the fine-tuning of gravity and of the cosmological constant and more!
Scientists discovered protein sequencing and exposed the myth of “junk DNA” and more!
Scientists discovered an even shorter Cambrian explosion period and the absence of precursor fossils and more!
Scientists discovered galactic habitable zones and circumstellar habitable zones and more!
And now rational people – people who want to have true beliefs about reality – need to abandon a false religion (naturalism).
Now naturally, science is in a state of flux and things change. But you have to look at the trend of discoveries, and those trends are clearly going against naturalism, and in favor of Christian theism. No one is arguing for a deductive proof here, we are simply looking at the evidence we have today and proportioning our belief to the concrete evidence we have today. People who are guided by reason should not seek to construct a worldview by leveraging speculations about future discoveries and mere possibilities. We should instead believe what is more probable than not. That’s what a rational seeker of truth ought to do. Proportion belief to probabilities based on current, concrete knowledge.
Atheism, as a worldview, is not rooted in an honest assessment about what science tells us about reality. Atheism is rooted in a religion: naturalism. And the troubling thing we learn from looking at the history of science is that this religion of naturalism is insulated from correction from the progress of science. Nothing that science reveals about nature seems to be able to put a dent in the religion of naturalism, at least for most atheists.
It falls to us Christian theists, then, to hold them accountable for their abuse and misrepresentation of science. And that means telling the story of the progress of science accurately, and accurately calling out the religion of naturalism for what it is – a religion rooted in blind faith and ignorance that has been repeatedly and convincingly falsified by the progress of science in the modern era.
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
Eight arguments:
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.
