Thus far, we have focused on traditional kinship-based religions, the only religion that existed for the vast majority of time. Now we take up the question of the relatively recent so-called world religions. “World,” or modern, religions are so designated, not because they necessarily exist in every part of the world, but because they are not confined to a set of kin, a tribe. They do not see themselves as true codescendants of a common ancestor. The first question we address in this chapter is how such religions arise. We propose that modern religions are created by prophets and their followers.
