German archaeologist Klaus Schmidt began excavating this site in 1995. What he uncovered over the following two decades forced a complete revision of the timeline of human civilization. Radiocarbon dating places construction between 9600 and 8200 BCE. That is 11,600 years ago. It predates Stonehenge by more than six thousand years. It predates the Egyptian pyramids by seven thousand. It predates agriculture.
