Well TureCreation this is all very detailed and fascinating stuff. We've got comets and floating flowers and selective fossilization and all sorts of ingenious answers.
Strangely, none of them are in the Bible. We are told about the gopher wood, and day of the month on which the flood started, and how big the window was, and how old Noah was, and which birds he sent out to find land. I wonder why these details are important?
The disposition of the earth after the flood, the massive changes in the landscape, the tectonic shifts,
BTW, when the dove returned with the olive leaf, how did Noah know it was because "the waters were abated" and that she hadn't picked one up from one of those pieces of driftwood you're so keen on?
Of course, one could ask how the olivetree or any other vegetation survived, never mind how it was able to put forth leaf after 150 days underwater?
But its all good clean fun and do keep on answering.
Of course all these geological and biological issues are petty compared to the really big questions about the flood.
How could a God of love and pure goodness deliberately kill babies, young children, unborn children in the womb? Being all-powerful he presumably could have found some other way to deal with the problem of mans wickedness.
If he was eternal and unchanging how could he "repent" that he had made man? Changing your mind over what you have created is hardly a benchmark test of infallibility, omniscience or unchanging eternal nature.
