Hey Animalman what is this 'Inherit the Wind' you spoke of? Sounds interesting.

As far as proven fact, yeah, you're right to say nothing can be proven in science. I'll rephrase and say evolution has a very strong case. Even Darwin was off. He thought animals slowly evolved bit by bit, so an evolving species had intermediate forms. But there is not fossil evidence of this. Instead, it looks like species change very quickly in the beginging of their existance and then stay static for a long time.
