Sean Carroll debates William Lane Craig on cosmology and God’s existence

Here’s the video of the debate:

Carroll was as good of a speaker as Craig in terms of style. Very easy to listen to, very quick on his feet, very civil. There was no clear winner on style.

It was difficult to assess the truth value of scientific points being made, especially for the layperson. I explained a few of them in my posts earlier this week, but I think laypeople might struggle with them if they are hearing about these things for the first time.

Quick summary: (this is not complete, because I couldn’t get everything they were saying noted)

Dr. Craig defended two arguments: 1) the kalam cosmological argument and the fine-tuning argument.

Dr. Craig supported the origin of the universe with 1) the expansion of the universe and 2) the second law of thermodynamics.

Dr. Craig said that the BGV theorem supports a beginning for the universe.

Dr. Craig said that the consensus of scientists did not accept Carroll’s naturalistic cosmology, quoting Stephen Hawking in support.

Dr. Craig said that multiverse models fall victim to the Boltzmann brain problem, where we should observe Boltzmann brains coming into existence and then phasing out again far more probably than embodied minds. But we observe embodied minds, and no Boltzmann brains.

Dr. Carroll said that science cannot study metaphysical questions.

Dr. Carroll said that science is about making models that may or may not be consistent with the experimental data.

Dr. Carroll said that the BGV theorem does not support a beginning for the universe.

Dr. Carroll proposed 17 alternative cosmologies, but did not provide a shred of scientific evidence for any of them, the way that Craig did for the standard model.

Dr. Carroll refuted Dr. Craig’s citation of Stephen Hawking, and Craig yielded the point.

Dr. Carroll speculated that science might progress to the point where the fine-tuning can be explained without an intelligent cause, and he gave an example of where that happened (inflation).

Dr. Craig argued that all 17 of the models suggested by Carroll either conflicted with evidence, had serious problems or did require a beginning.

Dr. Craig argued that Carroll’s own model required a beginning.

Dr. Craig argued that Carroll’s own model fell victim to the Boltzmann brain problem.

Dr. Craig argued that Carroll’s own model violated the second law of thermodynamics.

Dr. Craig re-stated his point that the baby universe spawning in Carroll’s model was speculative and incomplete, and cited Christopher Weaver’s work.

Dr. Carroll denied that things that pop into being out of nothing require a transcendent cause.

Dr. Carroll reiterated that science can only make naturalistic models, and that he did not have to answer questions about ultimate causes.

Dr. Carroll showed a photo of Alan Guth expressing his opinion that the universe is “probably” eternal. No evidence was given for this assertion.

Dr. Carroll said that the fine-tuning was not done in an optimal way, because one fine-tuned value was lower than it needed to be, and it should be exactly what it needed to be if God did it.

Dr. Carroll said that a finely-tuned universe is more probably in naturalism than in theism, because God can do anything he wants and doesn’t need a fine-tuned universe.

Dr. Carroll said he would stop defending his model now, and would instead defend Aguirre-Gratton.

Dr. Craig gave three reasons why the universe popping into being out of nothing requires a transcendent cause.

First, he said that nothing cannot cause anything to happen, because nothing is nothing.

Second, he said that if things pop into being out of nothing, then why don’t we see it happening all the time with other things.

Third, he said that we have no reason to dismiss the causal principle, especially when it is the basis of scientific inquiry and has been so fruitful in the progress of science.

Dr. Craig reiterated that baby universes in Carroll’s model would be dominated by Boltzmann brains, and we don’t observe that.

Dr. Craig said that even on the quantum gravity models that Carroll mentioned, there would still be a beginning.

Dr. Carroll said that Craig mustn’t say “popped into being” but instead that “there was a first moment of time”.

Dr. Carroll said that his model does indeed violate the second law of thermodynamics “YES!”.

At this point Carroll stopped talking about the topic of the debate and started expressing personal opinions about religion. It’s funny how often atheists do this in debates.

Dr. Carroll said that most theists don’t believe in God because of cosmology, but because of community and feelings.

Dr. Carroll said that science had learned a lot in the last 2000 years, so theism was false.

Dr. Carroll said that most philosophers don’t think that God exists, so theism was false.

Dr. Carroll said microscopes and telescopes were absent 2000 years ago, so theism was false.

Dr. Carroll said that religion should be about community and feelings, not about what is true.


My conclusion was that Carroll lost because he is just satisfied to throw theories out and not to argue that they are true by citing evidence. Carroll never seemed to be interested in finding out what is true, but instead he just wanted to tell a story that didn’t include God, and assert that by Occam’s Razor, his story was a better explanation. I am not impressed with theoretical speculations, although the layperson might be. I kept waiting for him to respond to Craig’s points about how his model was falsified by experimental evidence and observations, e.g. – the Boltzmann brains or the baby universe generation, and he never cited the evidence I wanted him to cite. Craig did have some evidence for his views, but he could have been stronger in making his case. He could have shown the e-mail from Vilenkin that stated that he had understood the BGV theorem, and was using it correctly, for example.

For me the winning side comes down to evidence. The standard model is the standard model because of scientific evidence. Until that evidence is overturned, then speculative models are of no interest to anyone who is evidence-driven. Speculations are not science. A philosophical presupposition of metaphysical naturalism is not science.

If you want to see a good lecture on scientific evidence related to cosmology, then there is the particle physicist Michael Strauss lecture on cosmology and fine-tuning at Stanford University and his more recent lecture at the University of Texas. Note that Strauss is an experimental physicist, not a theoretical physicist like Carroll.

Here’s another review of the debate by Randy Everist of Possible Worlds blog. He explains the back-and-forth over Boltzmann brains and the BGV theorem in more detail.

Greg Koukl explains the right way to handle an angry, aggressive atheist

A conflict of worldviews
A conflict of worldviews

Greg Koukl is one of the scholars who got me started in apologetics. In his “Solid Ground” newsletter for January/February 2009, he talked about dealing with angry, aggressive atheists.

Let’s start with the question “what is a steamroller?”:

The defining characteristic of a “steamroller” is that he constantly interrupts, rolling over you with the force of his personality. Steamrollers are not usually interested in answers. They are interested in winning through intimidation.

Greg breaks down the techniques for handling steamrollers in 3 steps.

Step 1: Stop Him.

Your first move when you find yourself in a conversation with a steamroller is a genial request for courtesy. Momentarily put the discussion on “pause.” Ask to continue making your point uninterrupted.

One of the ways you can do that is using body language. You can raise your hand in the stop motion to emphasize your verbal attempt to pause the conversation so that you can finish responding. Ask for a specific amount of time to make your point, and make sure that you him to agree that you will get that time to respond! But the most important thing is to not lose your temper.

Be careful not to let annoyance or hostility creep into your voice. That would be a mistake, especially with this kind of person. Don’t let a steamroller get under your skin. Being defensive and belligerent always looks weak. Instead, stay focused on the issues, not on the attitude. Talk calmly and try to look confident.

…don’t take unfair advantage of the time you buy with this little negotiation. Make your point, then ask, “Does that make sense to you?” This invites him back into the conversation. Give him the courtesy of offering you a reply without interruption.

I hear J.P. Moreland saying “Does that make sense to you?” all the time in his lectures, and now I’ve started doing it too! And so should you! But what if “stopping him” doesn’t work? Then we go on to step 2.

Step 2: Shame Him.

Suppose the steamroller interrupts you again during your negotiation response time. You want to gently draw attention to the fact that he is being rude and intimidating in the conversation. Again, the goal is not to show the slightest discomfort, but always to act with confidence.

Phase two of the Steamroller tactic is to shame him for his bad manners while maintaining your integrity. Stay on topic and don’t follow any “rabbit trails” he may voice.

That point about not taking on any new questions until you finish answering the first one is vital. Every time you make a point about the progress of science, they start complaining about how cruel God is to allow evil and/or send people to Hell. You have to get them to be patient while you answer their first question, before they can move on to the next.

Below is example of how to do step 2:

“Can I ask you a quick question? Do you really want a response from me? At first I thought you did, but when you continue to interrupt I get the impression all you want is an audience. If so, just let me know and I’ll listen. But if you want an answer, you’ll have to give me time to respond. Tell me what you want. I need to know before I can continue.” Wait for an answer.

Part of becoming a good ambassador is knowing how to gauge your opponent, and how much force you should use. Practice, practice! But suppose even step 2 doesn’t work. What should we do now?

Step 3: Leave Him.

The most difficult thing to do is to break off a defense, especially when there are people around listening in or even participating. Usually you do this when the person is moving the wrong way on the aggression scale. Greg cites a number of Bible verses to show that the Bible does support this kind of strategic withdrawal from an engagement that is going the wrong way.


The article concludes with some very useful points. First, you don’t have to win every debate. Just make your point and then let the Holy Spirit handle it from there. It is a mistake to think that you can change people’s minds just by talking to them at more and more. Mind changing usually happens much later, as the person weights both sides of the issues. So don’t rush, and remember, God values free will.

Second, always give an aggressive challenger the last word. This is the policy on my blog, where I get one rebuttal to a commenter, and then they get the last word. So far, I haven’t had to violate this in 5 weeks of blogging.

And let me just reiterate – do not lose your cool. A lot of arguing relates to your attitude under fire, especially for beginners who judge debates not on the evidence, but on appearances. You need to spend time studying in advance in order to get this confidence, and I do mean studying both sides, by studying debates. Under fire, the confidence you’ve gained through study, especially the study of debates, is more effective than your words.

What are the historical arguments for the empty tomb story?

I wanted to go over this article by William Lane Craig which includes a discussion of the empty tomb, along with the other minimal facts that support the resurrection.

The word resurrection means bodily resurrection

The concept of resurrection in use among the first converts to Christianity was a Jewish concept of resurrection. And that concept of resurrection is unequivocally in favor of a bodily resurrection. The body (soma) that went into the grave is the body (soma) that came out.

Craig explains what this means with respect to the fast start of Christian belief:

For a first century Jew the idea that a man might be raised from the dead while his body remained in the tomb was simply a contradiction in terms. In the words of E. E. Ellis, “It is very unlikely that the earliest Palestinian Christians could conceive of any distinction between resurrection and physical, ‘grave emptying’ resurrection. To them an anastasis without an empty grave would have been about as meaningful as a square circle.”


Even if the disciples had believed in the resurrection of Jesus, it is doubtful they would have generated any following. So long as the body was interred in the tomb, a Christian movement founded on belief in the resurrection of the dead man would have been an impossible folly.

It’s significant that the belief in the resurrection started off in the city where the tomb was located. Anyone, such as the Romans or Jewish high priests, who wanted to nip the movement in the bud could easily have produced the body to end it all. They did not do so, because they could not do so, although they had every reason to do so.

There are multiple early, eyewitness sources for the empty tomb

Paul’s early creed from 1 Corinthians 15:3-7, dated to within 5 years of the crucifixion, implies the empty tomb.

Craig writes:

In the formula cited by Paul the expression “he was raised” following the phrase “he was buried” implies the empty tomb. A first century Jew could not think otherwise. As E. L. Bode observes, the notion of the occurrence of a spiritual resurrection while the body remained in the tomb is a peculiarity of modern theology. For the Jews it was the remains of the man in the tomb which were raised; hence, they carefully preserved the bones of the dead in ossuaries until the eschatological resurrection. There can be no doubt that both Paul and the early Christian formula he cites pre-suppose the existence of the empty tomb.

The dating of the resurrection as having occurred “on the third day” implies the empty tomb. The date specified for the resurrection would have been the date that the tomb was discovered to be empty.

The phrase “on the third day” probably points to the discovery of the empty tomb. Very briefly summarized, the point is that since no one actually witnessed the resurrection of Jesus, how did Christians come to date it “on the third day?” The most probable answer is that they did so because this was the day of the discovery of the empty tomb by Jesus’ women followers. Hence, the resurrection itself came to be dated on that day. Thus, in the old Christian formula quoted by Paul we have extremely early evidence for the existence of Jesus’ empty tomb.

A few quotes from atheist historians not from Dr. Craig’s article: (thanks to Eric of Ratio Christi OSU)

Michael Goulder (Atheist NT Prof. at Birmingham) “…it goes back at least to what Paul was taught when he was converted, a couple of years after the crucifixion.” [“The Baseless Fabric of a Vision,” in Gavin D’Costa, editor, Resurrection Reconsidered (Oxford, 1996), 48.]

Gerd Lüdemann (Atheist Prof of NT at Göttingen): “…the elements in the tradition are to be dated to the first two years after the crucifixion of Jesus…not later than three years… the formation of the appearance traditions mentioned in I Cor.15.3-8 falls into the time between 30 and 33 CE.” [The Resurrection of Jesus, trans. by Bowden (Fortress, 1994), 171-72.]

Robert Funk (Non-Christian scholar, founder of the Jesus Seminar): “…The conviction that Jesus had risen from the dead had already taken root by the time Paul was converted about 33 C.E. On the assumption that Jesus died about 30 C.E., the time for development was thus two or three years at most.” [Roy W. Hoover, and the Jesus Seminar, The Acts of Jesus, 466.]

The early pre-Markan burial narrative mentions the empty tomb. This source pre-dates Mark, the earliest gospel. The source has been dated by some scholars to the 40s. For example, the atheist scholar James Crossley dates Mark some time in the 40s. (See the debate below)

The empty tomb story is part of the pre-Markan passion story and is therefore very old. The empty tomb story was probably the end of Mark’s passion source. As Mark is the earliest of our gospels, this source is therefore itself quite old. In fact the commentator R. Pesch contends that it is an incredibly early source. He produces two lines of evidence for this conclusion:

(a) Paul’s account of the Last Supper in 1 Cor. 11:23-5 presupposes the Markan account. Since Paul’s own traditions are themselves very old, the Markan source must be yet older.

(b) The pre-Markan passion story never refers to the high priest by name. It is as when I say “The President is hosting a dinner at the White House” and everyone knows whom I am speaking of because it is the man currently in office. Similarly the pre-Markan passion story refers to the “high priest” as if he were still in power. Since Caiaphas held office from AD 18-37, this means at the latest the pre-Markan source must come from within seven years after Jesus’ death. This source thus goes back to within the first few years of the Jerusalem fellowship and is therefore an ancient and reliable source of historical information.

So we are dealing with very early sources for the empty tomb.

Lack of legendary embellishments

The empty tomb narrative in the gospels lacks legendary embellishments, unlike later 2nd century forgeries that originated outside of Jerusalem.

The eyewitness testimony of the women

This is the evidence that has been the most convincing to skeptics, and to me as well.

The tomb was probably discovered empty by women. To understand this point one has to recall two facts about the role of women in Jewish society.

(a) Woman occupied a low rung on the Jewish social ladder. This is evident in such rabbinic expressions as “Sooner let the words of the law be burnt than delivered to women” and “Happy is he whose children are male, but woe to him whose children are female.”

(b) The testimony of women was regarded as so worthless that they were not even permitted to serve as legal witnesses in a court of law. In light of these facts, how remarkable must it seem that it is women who are the discoverers of Jesus’ empty tomb. Any later legend would certainly have made the male disciples to discover the empty tomb. The fact that women, whose testimony was worthless, rather than men, are the chief witnesses to the empty tomb is most plausibly accounted for by the fact that, like it or not, they were the discoverers of the empty tomb and the gospels accurately record this.

The earliest response from the Jewish high priests assumes the empty tomb

This report from Matthew 28 fulfills the criteria of enemy attestation, although Matthew is not the earliest source we have. Oh, well.

In Matthew 28, we find the Christian attempt to refute the earliest Jewish polemic against the resurrection. That polemic asserted that the disciples stole away the body. The Christians responded to this by reciting the story of the guard at the tomb, and the polemic in turn charged that the guard fell asleep. Now the noteworthy feature of this whole dispute is not the historicity of the guards but rather the presupposition of both parties that the body was missing. The earliest Jewish response to the proclamation of the resurrection was an attempt to explain away the empty tomb. Thus, the evidence of the adversaries of the disciples provides evidence in support of the empty tomb.

Note how careful Craig is not to imply that the guard tradition is historical, because we can’t prove the guard as a “minimal fact”, since it doesn’t pass the standard historical criteria.

See it used in a debate

You can see the arguments made and defended from criticism in this debate with the atheist scholar James Crossley.

This my favorite resurrection debate.

William Lane Craig and atheist Daniel Dennett discuss cosmology and fine-tuning

Two Rams butting heads: may the best ram win!
Two rams butting heads: may the best ram win!

Here is audio of a very interesting exchange between William Lane Craig and leading atheist Daniel Dennett.

This audio records a part of the Greer-Heard debate in 2007, between prominent atheist Daniel Dennett and lame theistic evolutionist Alister McGrath. Craig was one of the respondents, and this was the best part of the event. It is a little bit advanced, but I have found that if you listen to things like this over and over with your friends and family, and then try to explain it to non-Christians, you’ll get it.

By the way, this is mostly original material from Craig, dated 2007, and he delivers the speech perfectly, so it’s entertaining to listen to.

Craig presents three arguments for a Creator and Designer of the universe:

  • the contingency argument
  • the kalam cosmological argument
  • the teleological argument

He also discusses Dennett’s published responses to these arguments, and that’s what I want to focus on, since most of you are already familiar with Craig’s philosophical arguments for the existence of God.

Dennett’s response to Craig’s paper

Here is my snarky paraphrase of Dennett’s reponse: (this is very snarky, because Dennett was just awful)

  • Craig’s three arguments are bulletproof, the premises are plausible, and grounded by the best cutting edge science we know today.
  • I cannot find anything wrong with his arguments right now, but maybe later when I go home it will come to me what’s wrong with them.
  • But atheism is true even if all the evidence is against it today. I know it’s true by my blind faith.
  • The world is so mysterious, and all the science of today will be overturned tomorrow so that atheism will be rational again. I have blind faith that this new evidence will be discovered any minute.
  • Just because the cause of the beginning of time is eternal and the cause of the beginning of space is non-physical, the cause doesn’t have to be God.
  • “Maybe the cause of the universe is the idea of an apple, or the square root of 7”. (HE LITERALLY SAID THAT!)
  • The principle of triangulation might have brought the entire physical universe into being out of nothing.
  • I don’t understand anything about non-physical causation, even though I cannot even speak meaningful sentences unless I have a non-physical mind that is causing my body to emit the meaningful sentences in a non-determined manner.
  • Alexander Vilenkin is much smarter than Craig and if he were here he would beat him up good with phantom arguments.
  • Alan Guth is much smarter than Craig and if he were here he would beat him up good with phantom arguments.
  • This science stuff is so complicated to me – so Craig can’t be right about it even though he’s published about it and debated it all with the best atheists on the planet.
  • If God is outside of time, then this is just deism, not theism. (This part is correct, but Craig believes that God enters into time at the moment of creation – so that it is not a deistic God)
  • If deism is true, then I can still be an atheist, because a Creator and Designer of the universe is compatible with atheism.
  • I’m pretty sure that Craig doesn’t have any good arguments that can argue for Christianity – certainly not an historical argument for the resurrection of Jesus based on minimal facts, that he’s defended against the most prominent historians on the planet in public debates and in prestigous books and research journals.

This is a very careful treatment of the arguments that Dr. Craig goes over briefly during his debates. Recommended.

Positive arguments for Christian theism

The kalam cosmological argument defended in a peer-reviewed science journal

Here’s the peer-reviewed article. It appears in a scientific journal focused on astrophysics.

Here’s the abstract:

Both cosmology and philosophy trace their roots to the wonder felt by the ancient Greeks as they contemplated the universe. The ultimate question remains why the universe exists rather than nothing. This question led Leibniz to postulate the existence of a metaphysically necessary being, which he identified as God. Leibniz’s critics, however, disputed this identification, claiming that the space-time universe itself may be the metaphysically necessary being. The discovery during this century that the universe began to exist, however, calls into question the universe’s status as metaphysically necessary, since any necessary being must be eternal in its existence. Although various cosmogonic models claiming to avert the beginning of the universe predicted by the standard model have been and continue to be offered, no model involving an eternal universe has proved as plausible as the standard model. Unless we are to assert that the universe simply sprang into being uncaused out of nothing, we are thus led to Leibniz’s conclusion. Several objections to inferring a supernatural cause of the origin of the universe are considered and found to be unsound.

The whole text of the article is posted online here.

Here’s an excerpt in which the author, Dr. William Lane Craig, explains the Big Bang cosmology:

The monumental significance of the Friedman-Lemaitre model lay in its historization of the universe. As one commentator has remarked, up to this time the idea of the expansion of the universe “was absolutely beyond comprehension. Throughout all of human history the universe was regarded as fixed and immutable and the idea that it might actually be changing was inconceivable.”{8} But if the Friedman-Lemaitre model were correct, the universe could no longer be adequately treated as a static entity existing, in effect, timelessly. Rather the universe has a history, and time will not be matter of indifference for our investigation of the cosmos. In 1929 Edwin Hubble’s measurements of the red-shift in the optical spectra of light from distant galaxies,{9} which was taken to indicate a universal recessional motion of the light sources in the line of sight, provided a dramatic verification of the Friedman-Lemaitre model. Incredibly, what Hubble had discovered was the isotropic expansion of the universe predicted by Friedman and Lemaitre. It marked a veritable turning point in the history of science. “Of all the great predictions that science has ever made over the centuries,” exclaims John Wheeler, “was there ever one greater than this, to predict, and predict correctly, and predict against all expectation a phenomenon so fantastic as the expansion of the universe?”{10}

As a GTR-based theory, the Friedman-Lemaitre model does not describe the expansion of the material content of the universe into a pre-existing, empty, Newtonian space, but rather the expansion of space itself. This has the astonishing implication that as one reverses the expansion and extrapolates back in time, space-time curvature becomes progressively greater until one finally arrives at a singular state at which space-time curvature becomes infinite. This state therefore constitutes an edge or boundary to space-time itself. P. C. W. Davies comments,

An initial cosmological singularity . . . forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity. . . . On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.{11}

The popular expression “Big Bang,” originally a derisive term coined by Fred Hoyle to characterize the beginning of the universe predicted by the Friedman-Lemaitre model, is thus potentially misleading, since the expansion cannot be visualized from the outside (there being no “outside,” just as there is no “before” with respect to the Big Bang).{12}

The standard Big Bang model thus describes a universe which is not eternal in the past, but which came into being a finite time ago. Moreover,–and this deserves underscoring–the origin it posits is an absolute origin ex nihilo. For not only all matter and energy, but space and time themselves come into being at the initial cosmological singularity. As Barrow and Tipler emphasize, “At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the Universe originated at such a singularity, we would truly have a creation ex nihilo.“{13}

[…]On such a model the universe originates ex nihilo in the sense that at the initial singularity it is true that There is no earlier space-time point or it is false that Something existed prior to the singularity.

Every theist should be able to understand and defend this argument. It is a scientific refutation of materialism, and it is supported by six lines of scientific evidence – all of which emerged as science has progressed.

Scientific evidence:

  1. Einstein’s theory of general relativity (GTR)
  2. the red-shifting of light from distant galaxies implies an expanding universe
  3. the cosmic background radiation (which also disproves the oscillating model of the universe)
  4. the second law of thermodynamics applied to star formation theory
  5. hydrogen-helium abundance predictions
  6. radioactive element abundance predictions

Those are the scientific discoveries that have led us to the beginning of the universe, which support’s Dr. Craig’s argument.

Here’s a re-cap of the three main evidences for the Big Bang cosmology from Caltech. (Numbers 2, 3 and 5 from the list above)


Until the early 1900s, most people had assumed that the universe was fixed in size. New possibilities opened up in 1915, when Einstein formulated his famous general relativity theory that describes the nature of space, time, and gravity. This theory allows for expansion or contraction of the fabric of space. In 1917, astronomer Willem de Sitter applied this theory to the entire universe and boldly went on to show that the universe could be expanding. Aleksandr Friedmann, a mathematician, reached the same conclusion in a more general way in 1922, as did Georges Lemaître, a cosmologist and a Jesuit, in 1927. This step was revolutionary since the accepted view at the time was that the universe was static in size. Tracing back this expanding universe, Lemaître imagined all matter initially contained in a tiny universe and then exploding. These thoughts introduced amazing new possibilities for the universe, but were independent of observation at that time.

Why Do We Think the Big Bang Happened?

Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”

The article goes into detail about each of these three evidences.

This is the kind of evidence I expect all Christian theists to be using when discussing the question of whether God exists. Scientific evidence. When talking to non-Christians, we first need to show that we understand science, because science is a reliable and respected way of getting knowledge about the universe. Non-Christians do not accept the Bible, but they do accept science, so we begin evangelism with science. Science (experimental, testable, repeatable science) should set limits on what anyone can believe – including non-Christians, who might otherwise not be inclined to listen to Bible verses and theology.

The Big Bang is not compatible with atheism

According to the Secular Humanist Manifesto, atheism is committed to an eternally existing universe, (See the first item: “Religious humanists regard the universe as self-existing and not created.”). If something non-material brought all existing matter into being, that would be a supernatural cause, and atheists deny that anything supernatural exists. The standard Big Bang theory requires that all the matter in the universe come into being out of nothing. This falsifies eternal models of the universe, which are required by the atheistic worldview.

You should definitely print out both articles and get familiar with the arguments and the evidence. I have tried this argument out on atheists, and the response I usually get is that scientific discoveries will soon emerge that falsifies all of these six scientific discoveries. That sounds more like faith than reason to me. And we have to make it clear to others who are still deciding that there is a conflict between science and religion. Just not the one they’re expecting. Let’s make our decisions about what to believe based on what science is telling us today. Let’s hold accountable people who want to have a worldview that is based on speculations.
