ok but hibernantion while on board the ark still does not solve the problem that when the animals got out they would have had no vegetation to eat and the carnivores would have eaten the remaining animals.
And what about the humans in all this?? What did they eat? The animals they were supposed to be preserving? If you take the view that they took aboard grains then you have another problem in that grain rots. By the end of it all the would have run out of food long before the flood waters went.
Do i recall right that when noah got out of the ark he sacrificed somthing as thanks to god? Now where did that animal sacrifice come from? Surely not one of the animals he was supposed to be preserving??
