Megaliths, 9500 BCE
Megalithic stone circles of 30 metre diameter with stones 5 meters high have been excavated in Turkey. But they date to 9500 BCE, some 4500 years before the earliest recorded megalithic structures. Furthermore, unlike the more recent megaliths which were built by horticultural/agricultural societies these were built by village-dwelling hunter-gathers. They are also covered in carvings of birds, pigs, lions and snakes.
