Civilizaciones antiguas anteriores a la historia conocida

Ancient Civilizations Before Recorded History 7500 BC. You are in the middle of the Konya Plain in Central Anatolia, and the midday sun falls on a mound of earth that looks unremarkable from the outside. But if you could pierce through that crust of earth, accumulated over 9,000 years, and look down, you would see something no model of human history predicted: a city of 10,000 people without a single street, without a palace, without a visible temple, without a barracks, without a central market. A city where the only way to enter a house is through the roof. Where the dead are buried beneath the floor of the room where the living sleep. A city that functioned for 1,800 years straight and then vanished without violence, without fire, without invasion, without us knowing why.
