Peter Klevius: Why did ancient "Egypt"* have to copy Sumerians when equally old South-American Caral pyramid civilization didn't have to copy anyone?!
* There was no ancient "Egyptian" "Memphis" or "Giza", simply because these names didn't exist back then. And the name Memphis is the English transliteration of a Greek version (Μέμφις) of an Egyptian word of uncertain origin which earliest possible guesswork etymology places it some 2500 years after the Giza pyramids. The name Giza is derived from Arabic (which didn't exist back then but some 3000 years later) Er-ges-her, meaning "beside the high," referring to the Great Pyramid, but its etymology may come from a Persian word meaning "castle".
