Remember kids: most conspiracy theories are rooted in Nazi ideology that they used to justify their war crimes!
also the conspiracy that the Pyramids were built by aliens or “a more advanced civilization” actually has connections to racists (read: white Europeans) not believing that non-white people can make such impressive monuments (and a lot of pseudoarchaeology has connections to Nazi ideology/ comes from members of the Nazi party as OP said)
I looked it up to see if there’s any sources I could share with the class and found this article which I think explains/ goes into more detail that I can and greatly recommend Miniminuteman on YouTube he debunks archeology conspiracy and talks about interesting topics in really fun and engaging ways
(SO SORRY OP THIS WAS REALLY LONG)
