Issac Asimov wrote about how faith/religion might be just a 'bug' in our monkey brains, one we can conceivably 'fix' one day. It makes perfect sense to me why this bug would be exploited over and over throughout the centuries, so that we keep giving the clergy our money, basically. Also so that kings have the apparent 'right' to rule us.

I'm basically an atheist because of this revelation, but then again, it's not proof of a lack of creator: odds are still pretty high that we're all in a simulation anyway, and someone did have to create that simulation. Hmm.
