Can I just butt-in here. Has anyone read 'The Discovery of Noah's Ark' by David Fasold? And 'The Biblical Flood' by Davis A Young? Here we have two books that present contradictory evidence. In Fasold's book we are told that Noah's Ark is presently 6000 meters, on a hill in Turkey. And in Young's book we are told that a global flood is impossible, (it's a long story, but a good one)..
Fasold shows evidence such as drogue stones, that were discarded by the Ark and are still there, and makes a good case for the Ark being a giant reed ship covered in cement, with a hole in the middle. And what about Tehuanaco I think it's called, an odd city, that was once near the coast, at a great hight. And also 'Pangea' the land mass as it once was, suggesting 'catastrophism'. The descendants of Noah's family are listed, but they do not include the sub-saharan Africans or the Chinese. They are the indo-europeans-arians and semetic peoples, (Greeks, Libyans, Iranians etc.) So are we talking about an area-specific disaster, that wiped out.. not everyone? That seems to go against the Bible, because Jesus says that 'then the flood came, and washed them all away' or something like that.
Also you have to think about things like mosquitoes being carried on the Ark, which wouldn't have been able to survive in the sea, and tons of other evidence that a global flood is impossible. So what's the truth about it? It's beyond me.
