What is telling with this question is we automatically take it from the point of view of Christianity. The Great Flood. Scholars say the biblical story we know come from more ancient tales that was brought into Judaism. This is probably the case. Christians say no story predates the Hebrew one. Pride! Pride! Pride! Now is the tale true.
Supposedly there are more then 500 stories worldwide of a great calamity, a flood, these are not just in Judaic, Summerian, or Christain cultures but cultures that had no contact with us. Science has even said ther see evidence such a event happened. The worst part is the story, scholars think they know where our story came from as there are parallels in another older Gilgamesh Epic, but of course we turn to what we were taught. I think it's true something happened that came forward to us in stroies. It was given meaning. It sometimes seems because something is in writing it's exists. The magic of print is that it must be true. How can you discount what you see.
If the flood happened it doesn't prove Noah existed. You must remember you look at this from a certain perspective. Do you agree with the reason for the a flood is the question. Did you know the Tower of Bebel relates to the story of the flood. Stories are not suppose to taken individually, each one exists as part of a whole web. In the Great Flood did not happen then we can't go on to Babel and there would be no exodus. Understand the early Bible (Hebrew) was a mix of history, folklore, myth, poetry that told a story about Israel. We only borrowed it.
