Nothing wrong at all with an unorthodox view... especially if it can be backed by respected sources
Are you perhaps thinking about the Naqada Period ca. 3800 BCE, or even further back into the Badarian Period ca. 4,500 BCE, where Upper Egypt is beginning to show signs of being a hierarchical society with its own identifiable cultural traits? That isn't unorthodox at all Si-Amun that is proven. Or pehaps you consider the Nile Valley in its late Neolithic state ca. 6,200 BCE. Here we find 4 seperate and different societies developing lifestyles along the Nile River in what we later recongize as Lower Egypt, Upper Egypt, Lower Nubia, and Upper Nubia? Again not unorthodox at all, just proven.
As for even earlier Neolithic settlements the experts are working on it
i am willing to wait for them.
I suggest two really great books on these time periods in Ancient Egypt. It is hard to beat Toby A.H. Wilkinson's book Early Dynastic Egypt. Very poor on pictures but very rich in pure data. i am not kidding here it is very hard reading but well worth it if you really want to know about this period.
The next best is Oxford's History of Ancient Egypt edited by Ian Shaw. Rich in pictures, adequate in information, and not limited to just the early stages of Ancient Egypt but its full rich history.
Today it is recongized that Egypt's unity, unification period is almost completed by the Late Gerzean Period ca 3,200. So you are right Si-Amun it did happen earlier than most folks think it did. Again, not unorthodox but proven
You all have a great day! Ancient Egypt rules! and i mean really Ancient Egypt
