Why is lake van an archaeological site?

Answer 1

There is growing archaeological evidence that the Lake Van region is the oldest known site and possibly the locale for the origination of cuneiform, cultivated grains and domesticated animals.

Currently the generally accepted time-line is around 6,000 years or 4,000 BC. However a startling paradigm shift has occurred with the discovery of Gobekli Tepe which multiple radio carbon dating indicates 12,000 years ago or 10,000 BC.

This is significant as this more than doubles the previously oldest known man made structures which before were of the Pyramids and Stonehenge.
