Old Kingdom of Egypt
Toby Wilkinson, in his book "Genesis of the Pharaohs", proposes an origin for the Egyptians somewhere in the Eastern Desert. In addition, there is evidence that sheep and goats were introduced into the Nabta Playa from Western Asia about 8,000 years ago. There is some speculation that this culture is likely to have been the predecessor of the Egyptians, based on cultural similarities and social complexity which is thought to be reflective of the Old Kingdom of Egypt.
