Out on the far southeastern section of Turkey.....on a small hilltop...there's this ancient ruins that was discovered around sixty years ago, and in the 1990s....they'd dug enough up to set up a pretty serious discussion.
Here is a stone 'religious-area' (fair amount of stone cutting done), which they can date back to around 7400 BC.
What bothers the dig-crowd is that they had most humans of the time assigned the task of hunters....not the farmer or settler type. So constructing this site (others around too)....there was a fairly long period (probably more than ten years) that stone carvers were doing this business.
But I tend to have an even bigger question.
Once this was built....things stayed active for about a thousand years. Then....someone came along and covered the area up. They didn't dismantle or destroy the religious site....they simply buried it.
Why?
Most folks who go through some anti-religious situation....go to great lengths to destroy what stands there. These people didn't do that.
Amount of effort to cover it up? Even if you had three-hundred people....I'd take a guess that at least six to eight weeks (minimum)were spent in hauling the dirt up and covering the site.
So what happened? My humble guess is that ten to fifteen generations of folks from this region (draw a circle of 1,000 miles) made a 'walk' to this site every couple of years and locals who'd settled that region were getting frustrated with tens of thousands of people who'd show up. So one year, the locals did a quick burial of the site and announced some mysterious event had occurred and wiped out the whole site.
Maybe for another thousand years, locals knew the whole story but kept their mouth shut.
