I had never even heard of this before this comment. I have now learned it's a very unique geological formation in the Sahara consisting of concentric rings of raised stone. It appears to be entirely natural and the scientific consensus is that no city has ever existed on the site nor did human artifice have anything to do with its creation.

For someone to post a comment like "I thought everyone knew" is so egregiously deceptive and misleading that the comment should be flagged. It's tantamount to posting "I thought everyone knew area 51 recovered aliens from Roswell." It's a conspiracy theory masquerading as an ordinary remark.

Worse, it's one that uses a psychological trick to dodge the burden of proof, because "everybody knows", so if you ask for evidence, you're admitting you're not among the "knowing ones". "Everyone knows" is not evidence.
