"…Our study of the epic of Noah has two results: we have shown beyond any reasonable question that such a voyage never took place and could not possibly have ever occurred. And we have demonstrated that those who accept this tale are using not knowledge but faith—faith of that irrational variety expressed in the old quip as 'believing something that you know isn't true.'"
The National Center for Science Education has a paper which attempts to prove the story of Noah and flood is not true and that it never could have taken place.
It is mainly meant as a rebuke to creationists and other evangelical Christians who support them, but it applies equally to haredim who refuse to accept what the Ramabam (Maimonides) wrote so many centuries ago – everything in Genesis before Abraham is allegory meant to teach us ethical and moral things (Guide to the Perplexed) and if science should show that more of Tanakh (the Hebrew Bible) is not literally true, then those parts of Tanakh should be accepted by us as allegory, as well (his son's introduction to Ein Ya'akov).
