Which is a very old civilization, Mohenjo-daro (IVC) or Egypt?

The Indus Valley seems to be the oldest, now that Mani and Dikshit’s research has been published in the Nature Journal, which is a world recognized journal. Only 10-20% of the Indus Valley sites have been excavated, and the oldest sites seem very far apart. Bhirrana (7570 BC) is in Haryana in India, while Merhgarh is in Pakistan (7000 BC). There is also a city under water off the coast of Gujerat that is said to date back to 7500 BC as well, although this has not been substantiated yet. Given all this info, we can postulate that there might have been an older core to this civilization somewhere in the triangle between these cities. There is just so little that archaeologists know about the Indus Valley Civilization and so much to discover as the Indus Valley has more than 1000 settlements.

On the other hand, the civilizations of Mesopotamia and Egypt have almost run out of sites, since most have been excavated. The oldest site of Mesopotamia is Jaimo (7090 BC) and that of Egypt a comparatively young Naqada (4400 BC).

Although there are older farming settlements in the Lebanon, Syria and Turkey area such as Gobekli Tepe (9000 BC), Jericho (9000 BC) and Tell-es Sultan (8500 BC), there is no evidence that these were sophisticated enough or interrelated enough to constitute a civilization. Therefore the oldest is the Indus Valley Civilization, followed by Mesopotamia, and then Egypt.
