I've contended in another post
that Primitive Man created belief systems to try to explain the natural world around him. Then, Ancient Man refined, recorded and disseminated these beliefs and it's what we're still stuck with today.
Seeing how so many different cultures, spread out all over the world, created so many different belief systems seemingly independently, was the rise of religion inevitable? Have there been any cultures in recorded history that didn't have unsubstantiated beliefs? Are we wired in such a way that having any made-up answer was better than admitting our ignorance? Were the fairy tales better than nothing?
I would lean yes based on the historical evidence of so many religions that sprung up around the world. Is there another way to look at this or other factors explaining the pervasiveness of different religions over the course of history?
