Commendable effort my friend, but unfortunately I've never had bringing something like this up about the Flood be met with anything more than a dismissive hand wave and a "Jehovah could have handled that." So questions and observations like this never went anywhere:
How did animals like koalas, penguins, kangaroos, etc get from their respective environments to Noah's Ark? (God got them there)
It would be mathematically impossible to fit all of the animals, and food and water needed for every animal onto to the Ark described in the Bible, even if they were dived by the poorly defined "kinds." (Miracle)
Even if all the ice on Earth were melted there wouldn't be enough to reach the top of Mt. Everest. (The Flood caused some tectonic plates magic that lifted the land up higher out of the water, despite the total lack of geological evidence for this theory.)
Even if the amount of water needed to cover Mt. Everest were spirited into existence, the kinetic energy caused by its falling over a span of forty days would release so much heat that the entire planet would boil and the Ark would burn. (God rigged the physics.)
All of those herbivore animals that traveled over 12,000 miles to reach Noah now have to walk back with no food because all the plant life has been ravaged by a flood. (God cared for them)
All of the now carnivores (because apparently before the flood there weren't any, despite the clear fossil records of animals with other animals in their mouths and stomachs) can't eat anything either without wiping out an entire species. (God can control His creation.)
When the person you're telling this kind of stuff to can just invoke magic at any time, you may as well be debating a brick wall.
