I don't mean God in the sense of our modern concept of God. I've said before I mean in the more pagan sense. In Greek or Celtic myths, gods are different than humans mainly in being longer lived and being more powerful.
They weren't necessarily creators of the universe and all that. Even in Hindu philosophy, the gods don't create the universe, they're in essense mid-wives. other gods are born later. One Norse god gets maimed. One god fights or kills another in many myths. So our superman, Jedi, and X-men are probably closer to the pagan view of "the gods" than our monotheistic view.
