What about the plants, most of which would be destroyed in a flood violent enough to create the conditions supposed by flood geology? How long would it take to repopulate the world with all the animals starting with one breeding pair?
This can safely be filed with the recent “complexity disproves evolution” and science as a heresy if it causes doubt on literal Biblical language.
Most areas that have been flooded or for that matter wiped out by fire show signs of life within 1 year. Also any seeds that were not able to survive 1 year underwater may well have been found clinging to animal fur on the ark.
I find it amazing that 99.9% of all life forms are now extinct. And our ‘betters’ decided to blame man and create several gov red-tape outfits to ‘solve’ the problem.
Between the flow velocities needed to attain "hydroplate" migration of the continents, and the temperatures and pressures required to form fossils and sedimentary rock in the timeframe required, everything in the water should have been ripped to shreds and parboiled.
As long as it took the first time, probably? It's not as if this is a problem unique to Creationism. There will be one breeding pair at the head of any species under any explanation scientific or otherwise.
