About the best I might be able to do is take certain catastrophic occurrences we have been able witness, and then consider what might happen if these were amplified in magnitude so as to effect the entire planet.

Which is exactly what geologists did and what led them to realize there had never been a universal flood.

Yeah, but what if they're wrong, and even though there's no evidence for it, what if the Flood was real? My theory is just as good as yours. Teach the controversy!

Can't argue with you that some, if not many, geologists reject a global flood. They probably also assume that all geologic processes have taken place in basically the same way, at the same rates, and in the same magnitude throughout all time; IOW based upon the recorded observations in their field and personal experience, a reversal of current processes does not lead to evidence of a global flood.
