Cannot use your link, but I think I have read about this at other web pages--the Goblekli Tepe megalithic structures. It has academia on the run as it completely upsets their theories of the ancient world. One subject that is complete heresy in academia is the existence of prehistoric civilizations. However, here is the real evidence, a finely carved stone structure over 11500 years old. Over 22 acres and only 5% has been uncovered so far. The individual stone blocks weight from 7 to 10 tons.
The age was determined by radio carbon dating of animal bones found in it, but the stone work itself could be even older. The absurd official explanation is that it was built by primitive hunter gatherers as no civilization is allowed. It was supposed to represent a death cult although few human remains have been found. Construction of this place would have required extremely skilled full time stone workers not hunters doing it is as a hobby. They would need massive amounts of provisions. And then there is the missing tool problem as well as no vehicles or pack animals allowed.
The reason this place is so well preserved is that a short time after it was completed, it was
deliberately covered with sand. The structure is on top of a hill to begin with, and the sand forms an artificial round top to the hill. The builders had to be hiding it from someone, but the labor of covering it by hand was greater than what was required to build it in the first place. Although less skill would be needed to just carry sacks of sand.
