Is this the complete story? Didn't the Sea People wander out of the Black Sea, with metallurgy and chariots? Those were Celts.
It is almost entirely made up, which makes it a complete story. :')
Oh, those awful patriarchal societies just arose from nowhere (after 100s of 1000s of years of human prehistory) and oppressed the kindly, peaceful Great Goddess worshippers, who then, regretfully, had to arm themselves in self defense.
IOW, what a load of manure.
