Given the date, it’s possible, but it could also be contemporaneous. If the settlement dates from 7K ago, it would be 500 years after the so-called “Noah’s Flood” event that produced the Black Sea as we know it. As Ryan and Pitman note in the book of that name, Catal Huyuk in Anatolia was depopulated pretty much immediately after the event, and Jericho’s fortifications (as well as the fortifications of other ME sites) suddenly got much more formidable at that time.
The relics from before the Great Flood were likely washed away, which would be hard to find. Around the Great Flood, other parts of the world recorded it as well.
