The weird thing is that most comic book universes are crowded with gods, in which case there shouldn't be any atheists. I recall an issue of Iron Man where Tony Stark claims to be an atheist, and I was wondering about that. Tony Stark regularly partners with a god. And he's probably been to at least a couple of versions of heaven and hell. He's battled at least one or two versions of the Devil. He has encountered the beings that created the universe he lives in. But he's... an atheist???
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
