Debate: God Exists

[Neo-Scholastic]

If God is real, the high prevalence of animism and ancestor worship wherever 'civilized religion' has not been introduced becomes very perplexing if the God in question is supposed to be omniscient, omnipotent, and desires that people believe in it. You'd think everyone would be remarking on how frequently a new tribe is discovered that turns out to worship Jesus and Yahweh if Jesus and Yahweh are real and can communicate without human agents.

To some degree you are right. At the same time even the oldest known aboriginal traditions include some kind of 'Great Spirit' albeit a generally distant and indifferent being. Personally, I ascribe to the notion of progressive revelation so the idea that prehistoric and early pagan religion only partially reflect the fullness of the divine doesn't bother me all that much. That pattern is part of the growth of Christianity out of the prior Abrahamic, Mosaic, Prophetic and Intertestimonial periods, in that order. (As for Muslims, they are being deceived by a demonic "Angel of Light" as predicted by Paul)
