A study of how each god and his people were created for any group of believers is more telling than anything else.
Lets see:
we know the christain stuff already
not sure about or ME friends
budda? - came out a lotus flower
NA indians? - mother turtle came up from the sea and the people lived on her back.

Regardless of which one you look at they all seem to come from folk lore, superstition, and great imaginations. Not that it's all that bad nor should it matter, but to some it sure does.......
