Yes, and they are too far apart to be related to a global catastrophy. We know that civilisation is about 12000 years old, as that is when the climate stabilised enough for crops.
They also have been destroyed pretty much the same way.
The only flooding that happened very suddenly on large, but still not global scales, was the flooding due to the melting of glaciers at the end of the ice age.
It does when much of that melt is the size of a large lake, small sea, and suddenly bursts from an ice wall dam. That happened a lot around the ice sheets.
