Nonsense of Noah
Feeding themselves (humans) on the Ark would not be simple. Animals would have to be killed and dressed. Food would be eaten raw
What kind of food did Noah and his family eat?
Did it require cooking? If so, how was the fire contained? The ship was made of wood. There was no iron yet.
Oh - a rock and sand pit? Maybe. But, given that there was a huge amount of methane gas in the ship (result of animals' flatulance), what kept the Ark from blowing up?
How long would it take some of them to prepare just their food given that their crude stone-age utensils?
I am going to estimate that each human Ark inhabitant took eight hours/day for personal time (eating and sleeping)
