Some interesting posts regarding the IE language group:1) The earliest known Indo-European tongue is Hittite.
2) Hittite belongs to the Anatolian branch in the IE family, while Greek belongs to the Aryano-Greco-Armenic sub-family.
3) This proto-IE language theory is still just a theory.
4) There has yet been any proof suggesting that the IE tongue was initially spoken by whites. Just because there were stories of blonde hair-blue eyed people visiting parts of Africa and Mid East does not in anyway prove that they spoke an IE tongue.
