If you think that description you posted of the Navajo religion has any relationship to the beliefs or practices of traditional Navajo, you have a lot to learn about "awareness" of Western theistic (which includes Muslim, from the Navajo pov) descriptions of other peoples' religions.
I'm sure.
OK, we're getting into some strange territory now. Theism without deity - - -- tell you what, I will for the sake of argument agree with you that atheism does not exist except in certain insane individuals, and we will invent new words for whatever it is that you are talking about.
Brahmaan is not a deity that is worshipped anywhere on the Indian subcontinent, yet it is the essence of theism in varied Indian theistic beliefs. Just because its not your definition of "religion", does not make it any less their theism.
I'm sure that we can find some category word for the difference between the successful societies whose theism involves actual deities, like the Islamic paragons of durablility, and those whose theism is of this other kind not involving actual deities, such as the many examples presented to you.
No doubt. There are many many versions of theism and one can attempt to classify them according to our understanding of what they represent. But at the end, you're still left with the question: where are the surviving atheist societies?
