Lot of stuff happens, it appears that divine right+monotheism is better than polytheism for population control (reason why and how Islamic faith spread amongst the ruling class of adjacent countries).
The fact that monotheism "is better than polytheism for population control" is a completely orthogonal topic to the truth of the monotheistic claim. This in fact, is a logical fallacy called the genetic fallacy.
Your last statement is also a genetic fallacy.
The oldest recorded religion is hinduism. Polytheistic. The second oldest is zoroastrism and is duotheistic. The first monotheistic religion is athenism, based of the egyptian polytheistic faith, then Judaism, which probably is a mix of athenism (in the rites) and a mix of caanism and zoroastrism in the myth (lucifer story especially).
My point wasn't that monotheism is false because its better for population control, my point was it was adopted against polytheist faith and ancestor's cults faith across the word by the local ruling class because it was better at population control. I'm saying nothing about the truth of this particular faith
And i don't understand why my last statement is a genetic fallacy. I find people believing in 100% of the gods (or a deist) more interesting than those believing in one specific god.
