Pyramid building was a long and complex process. The Great Pyramid is composed of roughly 2,300,000 blocks and was likely built in 23 years or less . The Egyptians were careful and precise architectural planners.
There is actually a lot of evidence of the ordinary people who performed the building work, who weren’t aliens, but most definitely Egyptian. The work force was organized by crews. Each gang was divided into five groups of 200 men called zaa, also known by the Greek name ‘phyle’. Within each phyle were ten divisions of twenty men. The gangs seems to have been competitive and they actually graffitied their names on the buildings! The stones from some pyramids have hieroglyphs inscribed on them as notes which consist of the date of transport, the workmen in charge of the block, and the stage of transport.
