Ancient symbols carved into stone at Göbekli Tepe (an archaeological site in Turkey) tell the story of a big comet impact more than 13,000 years ago, scientists think. The devastating impact triggered a mini ice-age which drove many mammals weighing more than 40 kg to extinction.
According to an article published by New Scientist, carvings made on a pillar known as the “Vulture Stone” in Göbekli Tepe suggest that a swarm of comet fragments hit the Earth in around 11000 BC.
Göbekli Tepe was not only a religious site, but also may have been an ancient observatory, scientists think. Animal carvings on the pillar 43, also known as the Vulture Stone interpreted as astronomical symbols. Using a special software, scientists discovered a pattern between these carvings and the stars, and pinpoint the event to 10950 BC. This date is also corresponds to other evidence for the impact from a Greenland ice core, which suggests roughly the same time frame.
One image of a headless man is thought to symbolize human disaster and extensive loss of life.
Göbekli Tepe (means “Potbelly Hill” in Turkish) is an archaeological site atop a mountain ridge in the Southeastern Anatolia Region of Turkey. It contains the world’s oldest known megaliths – erected circles of massive T-shaped stone pillars were dated back to the 10th–8th millennium BCE.
Göbekli Tepe is one of the most important archaeological sites in the world – if not the most important. First noted in a survey conducted by Istanbul University (Turkey) and the University of Chicago in 1963, it could “profoundly change the understanding of a crucial stage in the development of human society”. According to the radiocarbon dating as well as comparative, stylistical analysis, it is the oldest religious site yet discovered.
Ian Hodder, the British archaeologist of Stanford University said, “Göbekli Tepe changes everything”. If, as some researchers believe, the site was built by hunter-gatherers, then it would mean that the ability to erect monumental complexes was within the capacities of these sorts of groups which would overturn previous assumptions. Some researchers believe that the construction of Göbekli Tepe may have contributed to the later development of urban civilization: Klaus Schmidt, the German archaeologist and pre-historian who led the excavations at Göbekli Tepe from 1996 to 2014, put it, “First came the temple, then the city.”
