In the Stargate universe, we had aliens acting as Egyptian Gods and Norse Gods. Now all polytheistic religions have been fought be the monotheistic ones, Christianity, Judaism and Islam. Is the ONE God, and his representatives like Jesus and Mohammad, also supposed to be a powerful alien? Any reasons why they didn't do it? The fight between polytheism and monotheism is one of the most interesting aspects of our culture. The idea that there was an alien who fought the Goa'uld "gods" and mercilessly slaughtered anyone who believed in them would have been interesting to pursue. Also the idea that he picked a certain special subgroup of humans and didn't care for anyone else who didn't believe in him.
