Holy fuck, finally someone not shoe horning racism into this somehow. Its not racism, these people think EVERYONE back in Egyptian times were stupid, not just non white people

That's true, but there's sort of a network of these different beliefs that tend to chain together into a belief system that, I would say, strongly correlates with sorts of weirdly racist conspiratorial shit. If you're willing to reject the invention of the microwave, this totally arbitrary thing, and say it was from aliens, it's pretty easy to blow that up and say that maybe the pyramids were also aliens. Like, you already believe in aliens, you already believe in a well-organized conspiracy capable of hiding facts, it's not that big of a leap to make that like, oh, maybe the aliens also did the pyramids. Maybe the aliens are here all around us already, and then bim bam boom bob's your uncle and suddenly you believe all this fucked up shit.

Then, you know, kind of, spin it out even further, and then a lot of this misinformation and conspiracy is going to come from fucked up kind of racist narratives and shit like that. The realm of misinfo and conspiracy is more occupied by that, almost by necessity.
