What of the plants? How did they survive months of inundation? And if they all died, but regenerated from seeds after the water receded, how did Noah's boatload of animals get by in the time it would take for that to happen? What, for example, of those animals which depend on tree fruits and tree nuts, products of trees at least several years old?
How did bees survive, in the absence of flowering plants?
And how does this story account for those living plants which have been alive since before the date ascribed to this Great Flood? Or those clonal colonies which have been alive since before the Flood without setting seeds?
Reasonable questions I would think.
Thanks. There are more too. Where, for example, did all the extra water come from? Enough to cover the world including the mountains. And where did it go to afterwards?
And this water, was it fresh or salty?
And how did water-living plants and animals survive, given that many are very sensitive to changes in salinity, temperature and light levels? How did the marine food web survive, when sudden change of depth and salinity and turbidity would have wiped out the seagrasses, algae and other life forms down at the bottom?
How do you account for coral reefs, some many thousands of years old, which can only survive across quite a narrow set of criteria, specifically including depth, clarity and temperature?
And the olive leaf the bird brought back. How could that have been found? Olive trees submerged for a year won't survive - even growing them in poorly-drained soil will soon kill them.
What would you feed your obligate carnivore animals on for a year on the Ark?
