Stone carvings confirm comet hit Earth 13,000 years ago
Analysis of symbols carved onto stone pillars at GÃ¶bekli Tepe, Turkey confirmed that a swarm of comet fragments hit Earth around 10,950 BC. The event wiped out animal species including mammoths and triggered a mini ice age lasting around 1,000 years, researchers said. The analysis matches time derived from an ice core from Greenland dating the event to 10,890 BC.
