It’s an interesting question, but...
I also think there is something inherent in the religions, independent of culture/civilization.
As evidence, I’d note that after the fall of Rome, Europe was invaded by barbarians, a tribal society also. Converting to Christianity was a key part of them becoming “civilized.”
ME tribes converting to Islam became unified; the question is whether this had any effect on them becoming ‘civilized’ in the definition used here.
There are three identifiable factions in our era: the new world order fascist/banker group, the new world order communist group, and the new world order religious murderer group.
