Has anyone ever taken the time to add up the sizes and weights of “two of every animal” that has ever existed and exists today, and added to that the amount of food, by weight and volume, all of these animals would need to sustain themselves for forty days (including the carnivores, the feeding of which would of course necessitate much more than just “two of every animal”), and then used such info to calculate just how large Noah’s Ark would have to actually be to pull this off?

I am no mathematician, but I’d bet Noah’s Ark would have to be at least the size of Japan, and much like a glacier, would have many more volumes of space plunging below the water line compared to what is visible above it.
