The great Atum was first worshipped at Heliopolis, about eight miles northeast of Giza, when the emphasis of the science of the zodiac was on the stars, not so much the sun, later added for the syncretized god Atum Re, which made the god a man/thing combo, while Atum was the first man, also known anciently as Adam, his real story told in the book of Genesis, that story obviously not etched in stone by the egyptians.
The egyptians also never reported when Menouthis and Heraklion sank beneath the waves of the Mediterranean (so not reported to Solon whose report was later recorded by Plato in Critias about Atlantis), but they did report the catastrophic climate change circa 1500 b.c. in the Ipuwer Papyrus, which was when the canopic branch of the Nile on which Menouthis and Heraklion were established began to dry-up, as the sea level rose, when the Ice Age was ending, not what you’ll learn in public schools for sure.
So when you look at those archaeological digs around Giza and Heliopolis, know that when that civilization was at its peak, green grasslands and scattered forests abounded, when the wadis were streams, and the Nile at Giza flowed much wider and deeper, all the way up to the plateau, with shallow lakes to the east and west which have long sinced dried up, as the climate was drastically different in new kingdom than old kingdom egyptian times.
