Göbekli Tepe (Turkish: [ɟœbecˈli teˈpe],[2] 'Potbelly Hill';[3] Kurdish: Girê Mirazan or Xerabreşkê, 'Wish Hill'[4]) is a Neolithic archaeological site in the Southeastern Anatolia Region of Turkey. The settlement was inhabited from around 9500 BCE to at least 8000 BCE,[5] during the Pre-Pottery Neolithic. It is famous for its large circular structures that contain massive stone pillars – among the world's oldest known megaliths.
Because it looks like a sand pit.
What makes it the most ancient site in the world? Looks like there is nothing there. Might as well get some olives out of the deal.
