Do remember, though, that belief in beings that exist outside of our reality (i.e., God) is not based primarily on the evidence. At least it ought not to be. This is not to say there is no evidence; on the contrary, I think the evidence for a god is rather convincing. But the evidence (in science, history, etc.) is not the basis on our belief.
Polytheism, I guess, is satisfactory to the extent that it gets God off the hook for bad things that happen in the world (the gods are not all-powerful -- there are many of them), and for seemingly contradictory forces at work in nature (i.e., the god of gravity working against the god of womens' breasts

). I say, though, that it is monotheism, which is more complicated and "risky," that requires us to think about these things and try to resolve them (e.g., how can a god be both holy and forgiving?). Etc.
