Got into a debate with a family member over the eye of Sahara

He’s convinced the Eye of Sahara is Atlantis, can anyone plead disprove this

More specifically does anyone have any counter arguments or know a good site that disproved this video? https://m.youtube.com/watch?v=r9Gj_6dmNc

I guess more more specifically can anyone counter the supposed claim of Egyptian records on Atlantis and the claim that the salt proves there was a lake there.
