I found this elsewhere, but it is mildly amusing :)
Atheism: The belief that there was nothing and nothing happened to nothing and then nothing magically exploded for no reason, creating everything and then a bunch of everything magically rearranged itself for no reason whatsoever into self-replicating bits that then turned into dinosaurs.
Well, it’s funny, but what’s hilarious is the story of a supposed infallible, omnipotent being having to test its own creation.
