>>11136725The mythical "copper culture" brought those mysteries to Egypt, chap. Via Doggerland sinking into the fucking ocean, no less. That's not to claim the three door religion was invented there, of course, those origins are currently obscured beneath 300,000 years of Pacific silt, most likely.
Egypt is "important" because the British Empire fell in love with its ruins. Our quarrelling awkward artistocratic sons just made shit up about the place trying to one-up each other, especially about its antiquity. There's irony there, given that England is the highlands of the sunken Doggerland.
