You have proof of this?

Because I have evidence of human tools being used to build the pyramids, of boats to transport the stones from the quarry, of the workers' own graffiti inside the pyramid (most of it along the lines of 'team xx built this', but I think there is one case of 'Arumphet is a knobhead' being scribbled on there), of stones broken through poor craftsmanship, of stones that were started on but never finished, of the burial mounds of the worker force, of their homes, of their towns, of human organisation, clear evidence of an evolution in thought and learning (the bent pyramid was not designed so, it became that way because they screwed up).

What proof do you have?
