The Goa'uld, having been separated from the Humans of Earth (Tau'ri) around 3000 BCE, named them the Tau'ri to mean "First Ones". In our history, the two histories being virtually identical aside from finding a stargate in Giza, there was a tribe, probably Greek in origin, called the Tauri that lived in the Crimean peninsula at some point between 1000 - 1 BCE.
Has anyone seen any reference to this duality in any canon or non-canon literature? Edit 6/16/21: In or out of universe. I was expecting any answer to this to be writers commentary or something similar, honestly.
