I don't have an opinion or an answer here, because I don't know enough about it. What I'm wondering is, what is the earliest well-characterized religion? Not a speculation based on a small handful of artifacts, but rather what is the earliest known religious theology? Was it ancient Egypt? Elsewhere - in the fertile crescent? India? East Asia? South America?
Im curious, thinking about the evolution of religions, did they evolve independently, with convergent evolution, or did they evolve from a single, primordial religion? Did religion create human society, or did human society create religion? Or did they co-evolve? It might be good to start with a "first".
