An atheist before Darwin could have said, following Hume: I have no explanation for complex biological design. All I know is that God isn't a good explanation, so we must wait and hope that somebody comes up with a better one. I can't help feeling that such a position, though logically sound, would have left one feeling pretty unsatisfied, and that although atheism might have been logically tenable before Darwin, Darwin made it possible to be an intellectually fulfilled atheist.

What has happened is that genetics has become a branch of information technology. It is pure information. It's digital information. It's precisely the kind of information that can be translated digit for digit, byte for byte, into any other kind of information and then translated back again. This is a major revolution. I suppose it's probably "the" major revolution in the whole history of our understanding of ourselves. It's something would have boggled the mind of Darwin, and Darwin would have loved it, I'm absolutely sure.

They are either people of faith who have lost their faith from reading my books, or they are people who had already lost their faith, and something about my books encouraged them to affirm that.

People sometimes try to score debating points by saying, Evolution is only a theory. That is correct, but it's important to understand what that means. It is also only a theory that the world goes round the Sun - it's just a theory for which there is an immense amount of evidence. There are many scientific theories that are in doubt. Even within evolution, there is some room for controversy. But that we are cousins of apes and jackals and starfish, let's say, that is a fact in the ordinary sense of the word.

And the beauty of the anthropic principle is that it tells us, against all intuition, that a chemical model need only predict that life will arise on one planet in a billion billion to give us a good and entirely satisfying explanation for the presence of life here.

In two senses: One is that you cannot go on the street and shout that you are an atheist, the other is that you are never given the intellectual framework for calling your faith into question.

I think the probability of a supernatural creator existing is very very low.
