There is no evidence for the existence of God.

40. We can define what would constitute evidence of other universes, but not of God

There are two lines of evidence for other universes. One would be if the physical laws in this universe require that there be other universes. So verification of the appropriate laws would constitute the evidence, even if we cannot contact the other universes directly. The second line would be if there were in fact a way to contact the other universes that we don't yet know about. Since that would imply a connection between our universe and the others, we would have physical proof of them.

But if you can't define what constitutes proof of God, then all you have done is precluded the possibility of proof prior to your investigation. This is like the way creationists preclude the possibility of evolution by declaring in advance that nothing can contradict the Bible.

We should also note that prior to the twentieth century, nobody had any problem defining God or providing proofs for or against. So what have we forgotten about God?
