So given certain conditions, the whole world should have been flooded for a good number of months then? Unless Noah was riding the tidal wave caused by the moon and never saw the land that was exposed...
This is the kind of thing where if I had the time, I'd like to really investigate the science/history behind. My view is that there is some truth to alot of the stories in the bible, but they are so old that the context really matters.
e.g. "40 days and 40 nights" = a really long time, more than I could count because I didn't have alot of schooling
"the whole world" = my whole world, my valley in Turkey
"2 of every animal" = 2 of every animal on my farm - cows, chickens, goats and sheep.
Very few people want to unpack this - it's like it either entirely happened or it entirely didnt, depending on your camp.
