I apologize for asking this question without having read Black Genesis, but the megalithic stone circle of Nabta Playa would appear to have a clear connection with the megalithic builders of Europe and the Mediterranean including other N. African sites such as Msoura in Morocco and elsewhere. Do you separate Nabta Playa from this megalithic culture and if so, why, and if not what connection do you make?
On a different note, it is generally agreed Egyptian civilization radically accelerated/changed around 3,200BC, but what is rarely touched on in both alternative and mainstream literature is the clear Mesopotamian influence on this process marked by the arrival of the "Dynastic Race" at Abydos at this same time. The Dynastic Race being invading "supplanters" as Petrie envisioned is no longer realistic, and I can understand why some today do not want to acknowledge the DR out of political correctness, but this does not change the fact they were there, likely serving an administrative function in the formation of the Egyptian unified state, and regardless could not be mere coincidence their arrival in Egypt coincides directly with this radical change.
Mesopotamian influence on the architecture of Sakkara could not be more clear and the extensive use of cedar wood at this time, among other things, leaves little doubt of more than a casual trading connection with Mesopotamia. Not to mention this is the site of the first step pyramid, similar to the Sumerian ziguarat. It is also with the arrival of the DR that the Egyptians adopt the King/Temple/Priest form of governance, clearly of Mesopotamian origin as well. Curiously, however, this influence appears to abruptly disappear at Sakkara with the odd exception of palace facade architecture found in the interior of Menkaure's pyramid.
There is much more to be discussed on this topic, but I am wondering what your thoughts about the Dynastic Race are and what level of influence do you accept the Mesopotamians had on on the formation of the Egyptian state?
Update to post: I am reading now above you are planning a book with David Rohl and refer to the Mesopotamian "boat people", so I suspect you have a pretty interesting view on the subject.
