The Arc story from the bible is historically and geologically in accurate. There has never been a world wide flood. Many different regions flood, though, and they all have myths about it. To me, the first four read like any other fairy tale out there. The rest of the bible, at least what wasn’t discarded due reasons we can’t know, seems historically accurate in events. Just as much as Homer’s Iliad and Odyssey had historical events within a work of fiction.
