Stone carvings confirm comet hit Earth 13,000 years ago

Ancient symbols carved into stone at an archaeological site in Turkey tell the story of a devastating comet impact that triggered a mini ice age more than 13,000 years ago, scientists believe.

Evidence from the carvings, made on a pillar known as the Vulture Stone, suggests that a swarm of comet fragments hit the Earth in around 11000 BC.

One image of a headless man is thought to symbolise human disaster and extensive loss of life.

The devastating event, which wiped out creatures such as woolly mammoths, also helped spark the rise of civilisation.
