It sounds to me like we are in agreement on some parameters. That makes it much easier to have a potentially helpful discourse.

This article presents a possible non-bubble-of-water scenario. I have not analyzed this in enough detail to form a strong opinion on whether the conditions described in the article satisfy all the requirement of the Noah story, but it looks worth investigating.
To sum up, 9300 calendar years BP fast inundation of land at least 120 meters (~400 feet) below sea level occurred. It was abrupt taking less than 40 years (in the article as few a 8) which means the deeper part of the Black Sea basin would fill for a few years and then the waters would come spilling across the shallow slope of the shelf (prime agricultural land) in much less time. Within that context, the rains comes, adding additional water and flooding. If you study the bathymetry of the Black Sea basin you will find some areas with a large shallow (1:1000 slope) shelf to the north east up to 120 miles wide. That’s possibly enough area to flood out a group of people as far as can be seen and as far as their entire settled area. The water-borne ark could drift west for up to 730 miles without ever coming in sight of land before running aground in the foot hills of the Armenian mountains in Georgia or Turkey. These foothills run right down to the present edge of the Black Sea and even into it. After running the ark aground, the story indicates that the waters then receded some amount leaving it stranded on dry ground.
For any YEC’s that have a problem with the 9300 BP date you can pick whatever date you want.
Note that this 9300 BP Initial Marine Infill date is distinct from much smaller flooding events that occur later. The original Black Sea deluge hypothesis [Black Sea deluge hypothesis - Wikipedia] was based on flooding events around 7550 BP (described in 1997) and 8400 BP (described in 2003) that turned out to be much smaller. This article (2017) details a much earlier and more dramatic flood event and represents newer information on the topic.
Think about it.
