I never really understand Flood threads on the JREF.
When Christians claim that Jesus died and came back to life, no one says "decomposition would have started immediately after death. Blood would have started pooling in the very first hour which would have given the resurrected Jesus a blotchy look that is not recoded in the Gospels. Furthermore cellular degradation would have made reanimation impossible after the cited time period."
But when Noah's Ark comes up, then everyone becomes a walking dictionary citing fact after fact indicating that without God's divine intervention no one could have met dietary needs, waste needs, breeding population needs, space needs, construction needs, joinery needs, etc. Yes! Without God's intervention, even the teeny-tiniest aspect of the Flood story is impossible. But if you are talking about a Being that created Heaven and Earth, then stopping animals from pooping is not that insurmountable of a task.
DISCLAIMER: I am not a fundamentalist Christian, I believe that fundamentalist Christians in the U.S. are a drag on society, I am not a Christian, I do not believe in any God, I do not believe that if the God of the Bible appeared before me that He would be worthy of worship in any way, I am aware of evidence in virtually every branch of scientific study that completely discounts the Flood story. There was no world-wide flood. I get that.
My point is if one is dealing with the Being that created every animal on the planet, then running the numbers seems to me to be a waste of time.
ETA:
I do, however, agree with the posters who point out that literal or allegorical, the story paints Yahweh as either an absurdly cruel dunderhead or a very-troubled victim of severe mental illness.
