Okay, you are a bit confused. After the last glacial maximum there were quite a few very strong local floods. But they occurred at different times. Israel and surrounding areas were too far south to be subject to those floods, the Black Sea flood is not a good example, they would have been affected by sea level rise only which though rapid in geologic time was rather slow in human measures. The Black sea flood did engulf several cities, but if one does the math by human measures it was still a rather slow rise. It took a year for it to be filled at the rate calculated. That would have resulted in a flood that a person could have crawled away from. Villages do not move rather well. They were engulfed. People were driven out homeless, but not flooded. Would you like a link to the flood that most likely gave birth to the myth? Right place, roughly right time, not global. The problem is that it would not have solved the supposed problems that were the cause of Noah's flood so the story is still a myth.
