Göbekli Tepe's carved megaliths are about 11,000 years old, roughly 6,000 years older than Stonehenge, and were made before the people who built them had developed metal tools or pottery.

Notes on verification

Multiple independent, reputable sources (History.com, HowStuffWorks, Facts and Details, Science News Today) corroborate the age, the comparison to Stonehenge, and the pre-metal/pre-pottery context. Minor variation in exact age estimates across sources does not undermine the claim.
