There's a difference between a force of nature and the god associated with the force of nature. I think you acknowledged this yourself when you talked about "deifying" things.Color me skeptical. You've been on the forums long enough to be confronted with god-concepts that are flatly absurd to disbelieve in. For most of human history, gods were basically mythopoetic personifications of very real forces that only someone who has seriously lost touch with reality would deny the existence of. The gods include natural forces, like the sun - which is quite possibly the most widely deified natural force in human history. The gods include social forces, like war - whose touch has cut deep and bloody swaths across human history as well. The gods include abstract concepts, like chaos - often characterized as a primordial abyss out of which all else came. If all god-concepts throughout human history are taken in sum, they very literally describe all of reality.
What I usually get from "atheists" when I point all this out is "but those things aren't gods," which is rubbish. The same rubbish is uttered by "theists" who insist their understanding of the gods is the only correct one. Neither stand scrutiny and recognizing how different peoples and cultures have understood gods. I always like it when I find folks who go "yeah, I understand this is how gods are understood in this context and respect that; to me, those things aren't gods because I define gods to be this; that's why I call myself an X, Y, or Z." Salix's question attempts to get at some of that important nuance, and I applaud that.
Worshipping, say, a rain god is not a matter of saying "yup - there's the rain, and it's my god all by itself." The god is typically the intentional intelligence that causes the rain, whether it's a mystical being that controls the rain or an intelligence assumed to be embued in the rain itself.
Ancient peoples were generally sincere with their imprecatory prayer: when they prayed for rain, they thought they were expressing their wishes to something that was capable of hearing them, understanding the request, and acting on it intentionally.
You seem to be suggesting that ancient peoples were all actually materialists who were only doing religion as some sort of performance art; this doesn't seem reasonable.
