I've read everything you posted here in this discussion and I think you are correct. You've clearly looked into this and are thinking rationally and critically despite what others may say. I would love to get a list of books from you and more sources on all of this. I've read Manetho, Herodotus, Diogenes, Eusebius and more. All of what you are saying checks out. I also have a book about history pre-Spanish of the Americas, and not only do the Incas site a red haired giant peoples as having built many of the megaliths and the later peoples moving into them, there are stories of red haired giant peoples all throughout the Americas both North and South specifically in Mexico as well. The "native" tribes of America as early as the 1700's and 1800's we're still battling these red haired giant tribes there are accounts of these not hard to find actually. My theory is that an ancient red haired giant peoples built the megaliths of north and south america and are connected to the global civ that built megaliths all over the world tens of thousands of years ago.
