This video has 3 parts, as well as questions and answers in individual clips.
For those who cannot watch the video, you can read this essay by Dr. Craig which covers exactly the same ground as the video. The essay is for Christians already familiar with basic apologetics.

Here’s a quick couple of quotes from the essay for those who cannot watch:
If there is no God, then any ground for regarding the herd morality evolved by homo sapiens as objectively true seems to have been removed. After all, what is so special about human beings? They are just accidental by-products of nature which have evolved relatively recently on an infinitesimal speck of dust lost somewhere in a hostile and mindless universe and which are doomed to perish individually and collectively in a relatively short time. Some action, say, incest, may not be biologically or socially advantageous and so in the course of human evolution has become taboo; but there is on the atheistic view nothing really wrong about committing incest. If, as Kurtz states, “The moral principles that govern our behavior are rooted in habit and custom, feeling and fashion,”5 then the non-conformist who chooses to flout the herd morality is doing nothing more serious than acting unfashionably.
The objective worthlessness of human beings on a naturalistic world view is underscored by two implications of that world view: materialism and determinism. Naturalists are typically materialists or physicalists, who regard man as a purely animal organism. But if man has no immaterial aspect to his being (call it soul or mind or what have you), then he is not qualitatively different from other animal species. For him to regard human morality as objective is to fall into the trap of specie-ism. On a materialistic anthropology there is no reason to think that human beings are objectively more valuable than rats. Secondly, if there is no mind distinct from the brain, then everything we think and do is determined by the input of our five senses and our genetic make-up. There is no personal agent who freely decides to do something. But without freedom, none of our choices is morally significant. They are like the jerks of a puppet’s limbs, controlled by the strings of sensory input and physical constitution. And what moral value does a puppet or its movements have?
[…]Moreover, if atheism is true, there is no moral accountability for one’s actions. Even if there were objective moral values and duties under naturalism, they are irrelevant because there is no moral accountability. If life ends at the grave, it makes no difference whether one lives as a Stalin or as a saint. As the Russian writer Fyodor Dostoyevsky rightly said: “If there is no immortality, then all things are permitted.”
If you want a much shorter, slicker version of this argument to share, Reasonable Faith has produced this nice 5-minute video that you can tweet or share on your Facebook page or whatever:
The moral argument is the easiest argument in the world to discuss with non-Christians, as everyone has to have an answer to questions like “what makes humans valuable?” and “why should I do the right thing when it goes against my self-interest?” and “will evildoers who escape justice in this life be punished when they die?” and “do humans have free will to make moral choices?” These are interesting questions, and people can just give their opinion and then think about it as they discuss it.
You can read a debate transcript where Dr. Craig puts his ideas to the test, against Dr. Richard Taylor. I found this debate very helpful for answering the question that everyone should be able to answer: “why should I be moral?”
I often hear atheists going on and on about how the Bible has this evil and that evil. Their favorite one seems to be slavery. Here are three things I say to atheists when they push this objection.
The Bible and slavery
First, you should explain to them what the Bible actually says about slavery. And then tell them about the person responsible for stopping slavery in the UK: a devout evangelical named William Wilberforce.
We should compare Hebrew debt-servanthood (many translations render this “slavery”) more fairly to apprentice-like positions to pay off debts — much like the indentured servitude during America’s founding when people worked for approximately 7 years to pay off the debt for their passage to the New World. Then they became free.
In most cases, servanthood was more like a live-inemployee, temporarily embedded within the employer’s household. Even today, teams trade sports players to another team that has an owner, and these players belong to a franchise. This language hardly suggests slavery, but rather a formal contractual agreement to be fulfilled — like in the Old Testament.3
Second, inform them that moral values are not rationally grounded on atheism. In an accidental universe, there is no way we ought to be. There is no design for humans that we have to comply with. There are no objective human rights, like the right to liberty (that would block slavery) or the right to life (that would block abortion). Although you may find that most atheists act nicely, the ones who really understand what atheism means and live it out consistently are not so nice.
Atheism and moral judgments

Dawkins has previously written this:
The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease. It must be so. If there ever is a time of plenty, this very fact will automatically lead to an increase in the population until the natural state of starvation and misery is restored. In a universe of electrons and selfish genes, blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, nor any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but pitiless indifference.
(“God’s Utility Function,” Scientific American, November, 1995, p. 85)
When people like Dawkins talk about morality, you have to understand that they are pretending. To them, morality is just about personal preferences and cultural conventions. They just think that questions of right and wrong are arbitrary. Things that are wrong in one time and place are right in another. Every view is as right as any other, depending on the time and place. That’s atheist morality.
What’s worse than slavery? Abortion!
Third, you should ask the atheist what he has done to oppose abortion. Abortion is worse than slavery, so if they are sincere in thinking that slavery is wrong, then they ought to think that abortion is wrong even more. So ask them what they’ve done to oppose the practice of abortion. That will tell you how sincere they are about slavery.
Here’s Richard Dawkins explaining what he’s done to stop abortion:
That’s right. The head atheist supports killing born children.
Dr. Graham Oppy, the moderator, is a well-known atheist philosopher. He let Dr. Krauss speak for 21 minutes and 40 seconds, which is why my summary of Krauss is so long.
The video:
Summary
After careful consideration, I decided not to be snarky at all in this summary. What you read below is what happened. There may be some small mistakes, but I will fix those if people tell me about them. I also included some quotes and timestamps for the more striking things that Dr. Krauss said.
The debate itself starts at 4:50 with Dr. Craig’s opening speech. He does use slides to show the structure of his arguments.
Dr. Craig’s opening speech. (4:50)
The kalam cosmological argument:
God is the best explanation of the origin of the universe
The Borde Guth Vilenkin theorem supports the absolute beginning of the universe
Even if our universe is part of a multiverse, the multiverse itself would have to have an absolute beginning
Speculative cosmologies try to challenge the Big Bang theory, but none of them – even if true – can establish that the past is eternal
Only two types of things could explain the origin of spece, time, matter and energy – either abstract objects or minds
Abstract objects do not cause effects, but minds do cause effects (we do it ourselves)
A mind is the best explanation for the origin of the universe
The unreasonable effectiveness of mathematics:
The underlying structure of nature is mathematical – mathematics is applicable to nature
Mathematical objects can either be abstract objects or useful fiction
Either way, there is no reason to expect that nature should be linked to abstract objects or fictions
But a divine mind that wants humans to understand nature is a better explanation for what we see
The cosmic fine-tuning for the existence of intelligent life
There are two kinds of finely-tuned initial conditions: 1) cosmological constants and 2) quantities
These constants and quantities have to be set within a narrow range in order to permit intelligent life
There are three explanations for this observation: law, chance or design
Law is rejected because they are put in at the beginning or matter – they don’t emerge from matter
Chance must be rejected, because they odds are just too long unless you appeal to a world-ensemble
We do not observe what the world ensemble hypothesis predicts that we should observe
Design is the best explanation for finely-tuned constants and quantities
The existence of objective moral values and duties
Our experience of morality (values and duties) is that it is objectively real and incumbent on us
When someone goes into a classroom and shoots at innocent children, that is objectively wrong
On naturalism, moral values and moral duties do not exist – they are conventional and variable by time and place
The best explanation for the existence of objective moral values and duties is that God exists
The historicity of the resurrection of Jesus
There are three widely-accepted facts that are best explained by the resurrection hypothesis
1) the empty tomb, 2) the post-mortem appearances, 3) the early church’s belief in the resurrection
Naturalistic attempts to explain these 3 boilerplate facts fail
The best explanation of the 3 minimal facts is that God raised Jesus from the dead
The immediate experience of God
Belief in God is a “properly basic” belief – rational even without arguments because of experience of God
Seems to be saying that logical arguments can prove false things “it’s nonsense”
Dr. Craig distorted a podcast that some group made on pain receptors
Dr. Craig’s faith is so strong that it causes him to distort what this group said
Discussion: (44:35)
I will not be summarizing everything that was said, just a few main points.
The segment from 52:18 to 57:12 about the Vilenkin e-mail on the BVG theorem is a must-see. Krauss is standing up and gesticulating while Craig is calmly trying to quote a paper by Vilenkin that shows that Krauss is misrepresenting Vilenkin. Krauss constantly interrupts him. After a while, when Craig exposes him as having misrepresented Vilenkin and gets him to admit that all current eternal models of the universe are probably wrong, he quietens down and can’t even look at Craig in the face.
Cosmological argument:
Craig: The e-mail says any universe that is expanding, on average, requires a beginning
Craig: There are two models – Aguirre & Gratton and Carroll & Chen – where there is a period of contraction before the expansion
Craig: The two models are the ones cited in the e-mail that Dr. Krauss showed
Craig: In the very paper by Vilenkin that I cited, he says that both of those models don’t work
Krauss: (agitated and interrupting) Vilenkin said that they have to make an assumption about entropy that they have no rationale for
(as Craig starts to talk Krauss makes an exaggerated, disrespectful gesture and sits down in a huff)
Craig: Yes, an unwarranted assumption means that they don’t have EVIDENCE for their theories being correct
Krauss: (agitated and interrupting) “All the evidence suggests that the universe had a beginning but WE DON’T KNOW!!!!!!!” (raising his voice)
Craig: I’m not saying that we know that the universe had a beginning with certainty
Craig: I am saying that the beginning of the universe is more probably true than false based on the evidence we have
Craig: And you agree with me about that – you think the universe had a beginning
Krauss: (agitated and interrupting) (Unintelligible)
Moderator: One at a time
Craig: In your Vilenkin e-mail slide, at the end of the paragraph where the two models are mentioned that Vilenkin specifically shows…
(I am guessing that Craig is going to ask why so much of what Vilenkin wrote has been cut out of the e-mail that Krauss showed)
Krauss: (agitated and interrupting) Because it was technical…
Moderator: Lawrence! Hang on a sec!
Craig: He specifically shows that these models are not past eternal, and that they require a beginning just like the others…
Krauss: (agitated and interrupting) We can do the math if you want
Craig: Now wait. I couldn’t help notice that there on your slide there was a series of ellipsis points indicating missing text…
Krauss: (agitated and interrupting) “Yeah, because it was technical!”
Craig: “I wonder what you deleted from the original letter”
Krauss: (agitated and interrupting) “I just told you!”
Craig: “Now wait. Could it have been something like this: (reads a quote from Vilenkin) ‘You can evade the theorem by postulating that the universe was contracting prior to some time. This sounds as if there is nothing wrong with having contraction prior to expansion. But the problem is that a contracting universe is highly unstable. Small perturbations would cause it to develop all sorts of messy singularities, so it would never make it to the expanding phase.’
Craig: “That’s Vilenkin.”
Krauss: “In this paper, that’s absolutely right”
Krauss: But it’s ok for theories to assume things that we know are wrong – they are still good theories – it’s unknown
(Craig turns away and looks through his papers)
Craig: “Isn’t it true that the only viable quantum gravity models on order today involve a beginning – have a finite past?”
Krauss: “No”
Craig: “Well, can you give us one then”
Krauss: (talks about a variety of possible eternal models) “In my experience in science, all of them are probably wrong”
Krauss: “You know most theories are wrong, which is why, you know, it’s hard”
Craig: “Right”
I noticed that a huge number of atheist web sites are taking the Vilenkin quote that Krauss used out of context, like this one and this one. There are probably a lot more of them like that, which I think is interesting. That’s why we have these debates, I guess. To set the record straight about who accuses people of being dishonest, and who is actually dishonest.
Fine-tuning:
Krauss tried to argue that he had explained the fine-tuning with the Higgs particle, but Dr. Craig said that only applied to the cosmological constant, not all the other examples of fine-tuning. Krauss said that it wasn’t impressive that this universe permitted life and that “It would have been much more surprising if we evolved in a universe in which we couldn’t live”. Krauss argued the fine-tuning was only for “Life like us”. But Dr. Craig explained that the fine-tuning is what allows us to have the basics of any kind of life, like slow-burning stars, chemical diversity, etc. – things that are required for basic minimal life functions in any living system. Craig said that he was working with the current physical laws of this universe (F = ma, etc.) and that he was looking at what changed if we changed those even slightly. Krauss tried to say that if he changed things like the mass of particles then the strength of forces would change. (But the forces aren’t laws!) Krauss argued that the cosmological constant would be even better for life if it was zero, and Craig said that the life permitting range did include zero, but that the range of life-permitting values was narrow.
Jesus’ existence:
Craig reponded to the mystery religions charge, the charge that the evidence for the minimal facts is too late/too weak, the charge that grief visions explained the evidence better, and Hume’s argument against miracles. Craig brought up the early creed from 1 Cor 15:3-7 and explained to Krauss that it was 5 years after the events, and that Jewish standards of oral transmission were strong enough to ensure that the creed was reliable, and most of the eyewitnesses would still have been alive.
Audience Q and A: (1:21:09)
The first topic is the grounding of morality. Krauss agrees that there is no objective morality and no objective moral oughts. He also said that that standards of behavior are arbitrary, and that they change over time and they are adopted for promoting social order. Dr. Craig pressed the point that science itself would collapse without ethical values. It assumes them, but cannot ground them.
The next topic was free will. Krauss is a determinist. Craig asked him how he could reconcile moral responsibility with determinism.
The next topic was the effectiveness of mathematics. Krauss didn’t have an explanation for it and didn’t think it needed one. Then they got into whether the Genesis has been verified by science and whether it is meant to be taken literally.
The next topic was whether philosophy makes any progress. Craig gave the example of verificationism being rejected as too narrow, and self-refuting. Krauss: “I’m going to come to the defense of philosophy for the first time”. Craig: “That’s amazing!” Krauss said that science provides new knowledge. Craig said there were some things that could be known apart from science.
