AKCHALLY turns out that's at the very least gigantically exaggerated - and sort of amplified by the completely false Old Testament account of Pharaoh enslaving the entire Jewish people and the exodus.
The current historical consensus suggests paid laborers and skilled craftsmen and engineers built the pyramids and the projects included a giant infrastructure to feed and house and care for workers. It seems likely that slave labor would have contributed to the projects but not as their driving force.
On the contrary, the pyramids were built in much the same way we'd find acceptable today- and every "miracle " of construction is explained through wealth, known construction techniques and common sense architecture-
There are even failed construction attempts where bad luck, geology or poor engineering created slumped pyramids, collapsed towers and so on. The aliens doing it has always been absurd. There's an easy evolutionary chart directly from stone and boulder mounds all the way to Giza.
Did the Egyptian pharaohs have slaves? Of course - but they were a mix of conquered peoples, internal castes and were specific to certain tasks.
The biblical account isn't even accepted by serious Jewish scholars and there's evidence of Semitic people living in Egypt at the time of the exodus as free or prosperous citizens- not slaves- and certainly not en masse
The exodus is probably based on a diaspora that occurred historically from Canaan and the region but had no factual connection to the story of Moses and pharaoh and is an amalgam of previous origin myths from the Semitic peoples and other cultures in the region.
