"You shall have no other gods before me." Is there anywhere in the Old Testament (or New Testament/Qu'ran, I suppose) that directly states no other gods exist? Abrahamic traditions may be able to reason the existence of another god by stating that it isn't the true God, the one worthy of worship. Most Eastern religions would be fine with a god being proven to exist. Buddhists could attribute it as yet another celestial Buddha, or a bodhisattva. Other religions in the region, such as Hinduism, don't typically limit themselves to a specific number of gods. If I understand correctly, it's kinda the same basis in logic as the Romans/Greeks; the more gods to worship/please, the better chances for a better life. Additionally, these types of religions focus more on the spiritual self than appeasing any particular deity. I highly doubt atheists would flip out, except maybe the really loud ones that always like to insult the religious...but those are so rare and we never see them anywhere, especially on the forums. Yup.
