I stumbled upon this interesting website, which I have not had the chance to read or digest, only skim. I don't know how scientific the information is, but there might be some good insights to be gleaned from it.
Ancient Egyptians and the Constellations
Come with me to the Celestial Hall of Records and discover the 16000 year old Celestial Sphinx, Hu, who was the blueprint for the Sphinx at Giza. Gaze upon the face of the Creator, the "Giver of Life in the Beginning".
Learn the Lost Word. Discover the greatest of the Lost Secrets of the remote Ancient Egyptians … including their knowledge of Precession which they encoded into their mythology, art and the Narmer Plate.
The remote Ancient Egyptians mapped the constellations, discovered Precession and invented hieroglyphs. It was they who introduced the arts and sciences to the rest of the world. Freemasonry is the legacy of the Ancient Egyptians.
