During a debate with the biologist Richard Dawkins, Collins stated that God is the explanation of those features of the universe that science finds difficult to explain (such as the values of certain physical constants favoring life), and that God himself does not need an explanation since he is beyond the universe. Dawkins called this "the mother and father of all cop-outs" and "an incredible evasion of the responsibility to explain", to which Collins responded "I do object to the assumption that anything that might be outside of nature is ruled out of the conversation. That's an impoverished view of the kinds of questions we humans can ask, such as 'Why am I here?', 'What happens after we die?' If you refuse to acknowledge their appropriateness, you end up with a zero probability of God after examining the natural world because it doesn't convince you on a proof basis. But if your mind is open about whether God might exist, you can point to aspects of the universe that are consistent with that conclusion.
