Archaeologists in southeast Turkey have discovered 20 sites belonging to a previously unknown Stone Age civilisation, now called the Taş Tepeler culture.
Dating back 11,500 years, it's considered the oldest known complex society, predating ancient Egypt and Stonehenge.
The civilisation developed monumental architecture, sophisticated sculptures, and potentially an early form of writing.
Excavations have revealed large settlements, ritual halls, and sculptures depicting humans, animals, and symbols of fertility.
Though advanced for its time, the Taş Tepeler culture collapsed around 10,000 years ago.
