For serious discussion of the controversies, approaches and enigmas surrounding the origins and development of the human species and of human civilization. (NB: for more ‘out there’ posts we point you in the direction of the ‘Paranormal & Supernatural

The evidence is overwhelming in favour of a Saharan culture being at the origin of the Egyptian civilization. I discussed this issue in great detail in my book (with Tom Brophy): Black Genesis.
We are presently working on the sequel, which brings further evidence of a Saharan origin for ancient Egypt.
There was other influx later, of course, from the East and the Levant (and much later from the West) that slowly merged and created the 'Egyptian ethnic strain' that is seen throughout Dynastic times.
