To this layperson, the narrative on Gobekli Tepe seemed fairly compelling. Here is a site situated at roughly the time and place grains first started being cultivated (per previous studies on ancient grains). A site where large amounts of meat was consumed, but animals not slaughtered on site. The animals where killed elsewhere and only the desirable bits transported there. And earthenware troughs believed to have been used to ferment beer. So a gathering site for nomadic hunter gatherers to gather at (festival? winter? just hang out?), at the point in time where we were starting to actually cultivate grains and stop being hunter gatherers and start being farmers. Other sites found dating later were definitely agricultural, with equipment for farming grains and animals and human remains showing the poor health associated with early agricultural settlements and the dense populations they allowed.
