“There is another side of Egypt that is not so widely known. Egypt is also the land of secrets. Another history, a secret history, tells of Egypt as the inheritor of deep wisdom and magical ability from an even earlier culture. It is the account of the Egyptians themselves. This alternate history is echoed by parallel accounts from the myth and history of other ancient cultures, as well as myriad secret societies and occult sources. The remarkable number of parallels in these stories provides a unique window into this other Egypt.
A new kind of counterculture is emerging around the unexpected discoveries of a small but growing circle of scientists, authors and researchers. The focal point of this counterculture centers on an alternative interpretation of ancient Egypt – not as mankind’s earliest attempts at primitive civilization, but as a fully developed, and inexplicably advanced culture, who’s scientific and metaphysical achievements we are only beginning to fully appreciate.”

Amun to that! It certainly agrees with my own research that I’ve been carrying out about the alternative history of Ancient Egypt. There is so much more than is currently known about them and their true origins, also their accomplishments. The evidence is there if you look for it as you suggest in your post. It’s a fascinating history and continuing story, and one that I am lead back to time again in my own life. Few people have come close to unravelling those secrets. I shall take a look at the documentary.
I just wanted to add that I have been carrying out this particular research for the past twenty years and what I have discovered really is truly amazing.
