Tamil the oriental language I had mentioned earlier that tamil was the language of the world prior to the white civilization.This is now getting proved by various quarters. The fact that the blacks were the orginal descendants of earth is well established by anthropologists.That world had one land mass prior to continental drifts is well known.Today we find blacks as primitives in all continents.you may take Eurasia ,Africa ,America, Australia,& Oceania.By negative propsition that none of river valley civilzation was fathered by the whites.It is also known that the movement of whites down soth from the poles might have been more than 10000 years.It is certain that tamil & tamil alike might have been source of communication.
