I think the more likely explanation is racism. If the pyramids were in Europe, nobody would challenge their human origin but pyramids are in Africa Surely aliens are involved.
Like I get it, you’re depressed, but this doesn’t automatically make everyone everywhere that doesn’t believe some random facts “racist”.

This isn't recent either. When Tolkien put the lines about Orthanc and the Stone of Erech looking unearthly into the Lord of the Rings, he reflected on the early Medieval people and their superstitions regarding Roman ruins. "There once was a race of giants that built X" was a common idea, and fanciful medieval authors would invent all sorts of humanoids that weren't human and were responsible for various wonders or evils.
Burial mounds in Ireland (sídh) are linguistically associated with the "fair folk" (aos sí) until today.
And why is it bad that people feel wonder at places literally called "wonders" and build stories around them? That's universal, not sinister. Egypt is steeped in religion, myth, and all kinds of craziness; most Egyptians don't hold a strictly secular, "logical" view of the world either, and no one calls them "racist" for it. From my time living in Cairo, people attributed most things to Israel and god, lol.
I also don't get tying a whole continent (an arbitrary construct) to a single race. There's no such thing as "the African race."
Weird comment. Hammers and nails, imo.
