It was bureaucrats, not space aliens (who built the pyramids)

One of the amusing parts of reading ancient history is finding that writing was not developed to write down stories but to keep track of commerce and taxes.

well, they have found the notes taken by the overseer of the workers making the Great Pyramid.

no, it wasn't space aliens, the stones were moved via canals.

Its entries are dated to the 27th year of Khufu’s reign, when the major remaining building task involved assembling the limestone casing that would cover the outside of the pyramid. Merer detailed the route by which the limestone was transported to the pyramid site from a quarry near present-day Cairo via boat along the Nile and a network of canals—a trip that took four days in all.

Now the question is how they were raised.
