#The question is a very bad fit in the first place
The question is a very bad fit in the first place
As you have said, you have studied these issues for 16 years. This isn’t a topic for a quick Q&A, this is the topic of books – plural, many have been published trying to answer that question.
To try to answer it in the SE format is, I think, absurd. An expert of your caliber might be able to do a summary justice here, and I’d be thrilled to see that answer, and upvote it – but I wouldn’t necessarily expect an expert of 16 years in religious studies to be answering questions on worldbuilding, and I don’t think the question belongs here in the first place.
So my ideal answer to this situation is to see your answer, upvote it, and then see the question closed anyway.
