The civilization of Kemet was not homogeneous. The Delta was a transcontinental highway connecting three continents.

Kemet was a multicultural society with many different populations of indigenous Africans transportating their cultures and traditions into the Nile Valley as well as populations of non Africans migrating back to Africa and settling in the Delta regions and along the costal lines of North Africa.

 

However the science and culture of Kemet was transported into the region by black Africans.

Nabta Playa being the region Africans studied the procession of the equinox from as early as 9,000 BC to 3,400 BC.

This is also the region and time period geometry and the concept of Pi was developed as well as the worlds earliest evidence of pastoral life.

Anthropological evidence proves these were black Africans in the area of modern day Sudan.

The 7,500 year old African mummy was found in the Green Sahara region and is the earliest evidence of ceremonial mummification nearly 2,000 years prior to the first discovery of the oldest Kemetic mummy.

Again these populations in the Green Sahara have been confirmed to be black Africans.

Extreme weather conditions forced both the populations of the Green Sahara and Nabta Playa to migrate to the Nile Valley and with them they brought the tradition of cattle worship, mummification, geometry and the study of the stars.

When the Nabta Playa region dried up due to extreme climate change this popultation of early farmers, pastoralists and scientists migrated northward following the flow of the Hapi (Nile) River bringing with them their knowledge and high science.

These Africans from the south would move into what would later become upper Kemet and establish the early Pharaonic Dynasties.

 

Menes (Narmer) would come from the south defeating the Delta dwellers uniting Lower and Upper Kemet unifying the various Nile Valley Tribes.

For the next 2,500 years or so Upper Kemet would act as the political, spiritual and power center of the nation.

The accumulated knowledge of thousands of years of the study of the procession of the equinox made it possible to transform the wet marshlands of the delta into the most fertile farmland in the world.

They would also use this knowledge to build the great pyramids and their mastery of sacred geometry allowed them to align the great pyramid nearly perfectly along the cardinal points—north, south, east and west—with an accuracy of better than four minutes of arc, or one-fifteenth of one degree.

The Nile Valley was populated by various tribes and populations from the Green Sahara, Uganda, Kenya, Sudan, and the Horn of Africa.

The emergence of Kemet was an evolution of African science, philosophy, and agriculture.

There is zero evidence of the culture or technology of non Africans immigrating back to Africa that had any significant contribution to the formation of the Kemetic civilization.
