sanskrit was the first alphabet

That makes sense to me Confused, though I had also heard Western Iran, specifically the Zagros Mountains as being another possible place of origin. I see a lot of the beginnings of Indo-Aryan culture originating in Anatolia however, domestication of sheep occurred there, many of the oldest neolithic settlements are found there including one of the oldest religious sites on record ( http://en.wikipedia.org/wiki/G%C3%B6bekli_Tepe ).

This is a personal theory of mine but I think that agriculture may have began on the coasts of the Black Sea, which was far lower during ancient times, and that water levels rose catastrophically circa 5600 BC due to the Mediterranean breaching the Strait of Bosphorus and flooding these regions, causing the survivors to relocate and spread elsewhere. I can see this also as the root of the Flood myth present in all cultures in the area. You can read more about the Black Sea Deluge hypothesis here http://en.wikipedia.org/wiki/Black_Sea_deluge
