Most of us tend to think of Noah as much less advanced than we are. Actually, the opposite would be true. We've had 4,500 more years of the effects of sin and the Curse on our brains. I'm convinced Noah would have had the intelligence necessary to devise methods of feeding and caring [for the animals on the ark] that would put today's farmer's to shame. If farmers today have methods that could easily allow eight people to look after 16,000 animals - I've no doubt Noah could do much more!
