There is a good article here:
Mysterious 12,000-Year-Old Gobekli Tepe
It seems that this 30 acre place was purposely buried. The article tries to explain what might have happened to cause the people to bury the site. They lead into the possibility of meteor swarm hitting the earth. They go into the presence of Lechatelierite (The same thing as trinitite from the Trinity nuclear site at White Sands Proving Ground. It can also be caused by lightning strikes.) at various areas around the world that date to the same time the site was buried. They are inferring that the people there buried the site to protect it from the effects of the meteor swarm.
I'm not buying it. Whatever happened caused animals as large as mammoths to be flash frozen. I'm sure you heard about it before. Those were the mammoths that were frozen so fast that they still had the buttercups they were eating in their mouths.
Two things struck me as odd about this theory. First, how would those people have had time enough to carefully and completely bury a 30 acre site that had monoliths as least 19 feet tall? The mammoths didn't even have time to spit out their buttercups. Second, have you ever heard or read about the presence of Lechatelierite at the Tunguska site? I haven't. If Lechatelierite can be caused by meteroite airbursts, why isn't it found at Tunguska?
Now consider the war mentioned in the Vedic writings. If there really was a war as described in those texts the people of Gobekli Tepe would have had time to bury the site and that might explain the Lechatelierite.
Politicians hide themselves away
They only started the war
Why should they go out to fight?
They leave that role to poor
