Finally I will submit this piece of wall art found in the tomb of Seti I, depicting representatives from Libya, Nubia, the Levant, and Egypt, demonstrating how Egyptians perceived themselves among their neighbors in terms of skin color and dress.

For the record: Libyans ("white" nort Africans) did the same during the 23rd dynasty.

The stereotypically "African" cultures Afrocentrists focus on are Kushites or Nubians of Northern Sudan who peacefully integrated, Egyptianized and ruled Egypt for almost 2 centuries years during the 12 Dynasty, as clearly evidenced by archeological records.

This is well evidenced by artistic records, historical records, and modern genetic testing.

2. Egyptians built in limestone, not because they were "rich", but because it was an accessible resource that was easy to work with.

A few corrections to the esteemed Dr. Carr:

1. Egypt has never been racially monolithic and has always had significant mixing in it's local population from Mediterranean, Levantine, North African, and Sub-Saharan ("black" as you put it) stock.
