Science is a process used to examine and explain our world.
Once something is falsified unequivocally it is then put aside. The examination of our world with the flood "hypothesis" in mind was done about 200 years ago. The hypothesis failed these tests.
To continue to espouse the idea when there is no new evidence to support it and lots more to falsify it is NOT a scientific approach.
This thread covers just one of the many lines of evidence that are unexplainable by the flood "hypothosis".
