Parrakeet-
"Who's a Silly Boy then?"
Genesis says there was a window 15 inches high around the top of the ARk. Of course they could fly away!!
Of course the window was inadequate ventilation for a vessel that size, and the daily piles of dung could not be got out very quickly.
Of course CO2 is heavier than air and would build up on the lower decks and suffocate the animals down there (the BIG one that need lots of O2)
Of course the build up of methan e from the shit would be highly flammable so Noah and sons did not use any lamps down there to find the lumps of dung for fear of blowing the crate up.
Of course God moves in mysterious ways his wonders to [perform.
