I've heard that there was a great Vedic society of legend that also disappeared some 4K(?) years ago, whose people spoke "Indo-European", a language that gave rise to Sandskrit, Greek and Proto-Germanic. It was the society from which the Vedas come from, the oldest scriptures known.
Linguists believe that all the Indo-European languages (The Mother Tongue) originated in Anatolia. It may have been spread far and wide from this point by the refugees from the Black Sea (Noah's) flood?
