Göbekli Tepe is the oldest megalithic structure on earth, predating Stonehenge by 6600 years and the Pyramids by 7100 years. Göbekli Tepe, or “Potbelly Hill” in Turkish, is possibly the most important archaeological discovery of this century, atop a mountain ridge in the Southeastern Anatolia Region of modern-day Turkey, approximately 12 km (7 mi) northeast of the city of Şanlıurfa. It was discovered in 1995 by archeologist Klaus Schmidt. What makes this site so special is not the age but the implications regarding the onset of the Neolithic period when humans first settled in permanent communities in a fixed location. I have previously written on the ragged edge between the Paleolithic hunter-gatherers and the more sedentary Neolithic settlements. Specific markers such as pottery, domesticated animals and cultivation of grains were discovered, forgotten and rediscovered over millennia before the lessons took root in the Neolithic package. Göbekli Tepe demonstrates another indistinct marker, special use megalithic buildings, possibly temples, built by Paleolithic hunter-gatherers.
