The cliche is that the pyramids were tombs to honor dead Egyptians.
However,
“No contemporaneous bodies, mummies or human remains have ever been found in any of the Old Kingdom pyramids.”
History.
P.S. All those old kings were slaveholders.
If what you say is true, then Egypt should look to be paying reparations to all the slave decedents instead of rebuilding a massive symbol of slavery.
Maybe those people in California calling for reparations can advise the Egyptians.
