Evidence for Noahs Global Flood

[iCambrian]

Ha, just kidding...

But, there is evidence for local, large floods. While the majority of change might occur through gradual deposition, erosion and orogenesis (among other processes), there is still room for floods, and evidence for floods. Even very large ones.

[Uthman bin Madhun]

In Islam, a dominant opinion is that it was a local flood and not global one.

Another "problem" is that the Flood didn't last long enough to leave any geologic traces.
