What are the top ten oldest civilizations in the world?

The answer would depend on what you call a civilization. If you will call a civilization. If you would accept a city, the first place would be Dwarka, which is dated back to 32,000 BC. If you want an entire empire, the oldest is the Rama Empire, 15,000 BC. The Ainus of Japan are next, then the Pacific Islander Aroi Kingdom. Mesopotamia would be far from the oldest.
