exception. there's a huge trend toward alien theories about human achievement based on geography. you can bet your ass even if something like the colosseum was in central africa people would be saying it's alien tech.
The colloseum was built in a time and place with written records. The pyramids were not. Same for any other massive structures that get the "aliens built it" treatment. Even Mayan architecture, which comes from a time and place with written records, only got this treatment because Mayan hieroglyphs were unintelligble to most folks, including the people in the region itself.
Contrary to what one might expect, there are no hieroglyphic texts, treasures, or mummies in any of pyramids of Giza. Decoration inside pyramids began several centuries after those of Khufu, Khafre, and Menkaure were constructed
While lacking the panache of Abu Simbel or Karnak, there were written records in the Great pyramids. Mostly work graffiti and seals, as far as I can learn, but that would count.

Those that do exist have all been explained by aliens at one point or another.

That makes sense, the total lack of sun means they lost the use of dark skin genes, or maybe they were cursed by God and cast out on the island, you never know
Lack of sources? We have tons of fucking sources. We know a LOT about the pyramids and have explicit writings about them from the times many of them were built. The (rich) Ancient Egyptians were very relatively recent and well-documented.
