The alleged event appears to pre-date the Göbekli Tepe site itself by at least 1,500 years, which seems at odds with the idea that the carvings were intended as observations of it.
Ancient stone carvings confirm that a comet struck the Earth around 11,000BC, a devastating event which wiped out woolly mammoths and sparked the rise of civilisations, says the Daily Telegraph.
Experts at the University of Edinburgh analysed mysterious symbols carved onto stone pillars at Göbekli Tepe in southern Turkey, to find out if they could be linked to constellations. The markings suggest that a swarm of comet fragments hit Earth at the exact same time that a mini-ice age struck, changing the entire course of human history.
Scientists have speculated for decades that a comet could be behind the sudden fall in temperature during a period known as the Younger Dryas.
