Hunter-gatherers built a massive stone temple 6,000 years before Stonehenge

Göbekli Tepe in southeastern Turkey, dated to roughly 9600 BC, has rings of carved limestone pillars weighing up to 10 tons, built before pottery, writing, the wheel, or even settled farming existed in the region. It was deliberately buried under rubble around 8000 BC for reasons still debated, which is partly why it survived intact for archaeologists to find in the 1990s.
