Physical pole shift would explain some of the same actions. Actually, something passing close enough to the earth might have triggered a pole shift.

THAT is not something you really want to have happen again. At least not while anyone you love is still alive.

Let's say it was a HUGE asteroid type Earth grazer ~ and swooped by Earth low enough to pull up large tides in bodies of water. So it comes along from East to West over the Mediterranean. It moves enough water to cut a channel on the East end and open up a flow of water from the Mediterranean to the Black Sea basin.

That would give us a date for the burial of the site ~ and, koinkydinkily, an event that could be timed perfectly with the use of Sumerian astronomical observations. Following the catastrophe (about 8,000 years back) folks would have lost memory of the use of the funeral/memorial site.
