@izzythepush,
Egypt does not want any group of slaves to be credited with building the pyramids even if it were true. If the pyramids were built with slave labor, it tarnishes their biggest accomplishment. The man has a self-serving narrative to protect Egypt ego. It is absurd to believes that in a slave-based economy that slaves were not used to build the pyramids.
Egypt was a major slaver and had a slave-based economy. The slaves were portable and the only ones who would push and lift huge stones.
They reason backwards they start with the conclusion and then look for fragments of proof to prove it. They filter out the fact that Egypt was a major slaver, and things get done in a slave state by slaves. Do you really believe the slaves stayed home in the lap of luxury while the Egyptians did the heavy work? That would be like believing in the old south that the work was done by the whites while their slaves took it easy under shade trees.
Egypt was trying to defend itself from anyone getting credit from building the pyramid's whether it be Israelis, Israelites or Africans.
