Klaus Schmidt says: "Gobekli Tepe is staggeringly old. It dates from 10,000BC, before pottery and the wheel. By comparison, Stonehenge dates from 2,000BC. Our excavations also show it is not a domestic site, it is religious - the world's oldest temple. This site proves that hunter-gatherers were capable of complex art and organised religion, something no-one imagined before."
