*Support #1 - for reasons already stated 

 ===compromise?=== 

 A compromise has occurred to me, inspired by the WP:NPOV page.  We can tweak the wording and tell both significant views in the intro neutrally: 

 *In Abrahamic religions, Noah's Ark was a large vessel... While many modern scholars treat the story within Judeo-Christian or Islamic mythology, there are still today a number of denominations and sects within the framework of all major Abrahamic faiths who continue to teach the deluge as a historical event. 

 ::This fact should also be explained for the benefit of the reader within the article: There are various denominations and sects that take a more historical view of the Old Testament and/or Quran accounts; or in the case of the Orthodox Tewahedo Church, the Old Testament in addition to Jubilees and I Enoch (the latter, they teach, was written before the Deluge.)
