“people believe in God because the world is very complicated and they think it is very unlikely that anything as complicated as a flying squirrel or the human eye or a brain could happen by chance.”

“But I said that you could still want something that is very unlikely to happen.”

“Also I didn't have 20/20 vision which you needed to be a pilot. But I said you could still want something that is very unlikely to happen.”

“And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.”

“And it means that sometimes thing are so complicated that it is impossible to predict what they are going to do next, but they are only obeying really simple rules.”

“I think prime numbers are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them”
