Gobekli Tepe, located in southeastern Turkey, is an archaeological site dating back to the 10th–8th millennium BCE. Its complex of massive stone pillars arranged in circles predates Stonehenge by several millennia, pushing back the timeline of known human architectural activity. Their existence suggests that organized religion could have come before the rise of agriculture and settled communities, a theory that contradicts the conventional understanding of human history.
