According to one book of fiction, the claim that the world could not have evolved by chance is the final proof of the non-existence of god.
The argument goes something like this:
"I refuse to prove that I exist", says God, "for proof denies faith, and without faith I am nothing."
"But", says man, "the world is a dead giveaway, isn't it? It could not have evolved by chance. It proves you exist, and therefore, by your own arguments, you don't. QED."
"Oh dear", says God, "I hadn't thought of that", and promptly vanishes in a puff of logic.
(Adapted to to this thread from "the Hitchhikers guide to the galaxy" on the Babel Fish. It is really the Babel Fish that is the dead giveaway, but since creationists think that the world could not have evolved by chance, the argument is the same.)
