I think you're being carried away, 30 thousand years is a bit exaggerated. There is no written or archaeological evidence of any civilization in the whole continent of Asia that old, not to this day. India and China each claim they are 10,000 + years old (which the West deny) civilization to show how important they are in the history. The oldest Indus civilization found so far (maybe they will finder older later) is not more than 6,000( max) years old, mature period. 

I get sick and tired of Indian and Chinese friends who compete of how old their civilization are. My simple answer to them is, if being old is so important, let us ask our African friends. After all human beings started from Africa, imagine some of the ancient civilizations yet to be discover in Africa. They will beat your oldness.
