I presume you've seen Patton Oswalt's explanation of the origin of religion.
Great videos, both Nikk and Leah.My only problem is, from an historically theological standpoint, neither of these address the most common primitive religious belief regarding the afterlife: reincarnation. The Greeks, Romans, Persians, Egyptians, all basically all surviving Eastern religions, most original American tribes, and even newer faiths like Scientology all believe in a cyclical view of life, not a linear one. I suppose telling a strong person they may come back as a weakling would have the same effect.
