The book goes into more detail regarding the diets of other animals, in Chapters 12 and 13. If an electronic copy were online, I'd provide the link for you to read for yourself.
Tell me about animals that foraged. How was supply of vegetation, especially for the larger animals kept. Things like berries, roots, and even leaves die off unless they are still on the vine or branch and how did they replenish so fast if daily feedings stripped the plants of leaves, etc.?
Again, you'll have to read the book for yourself. What I've posted is but a small fraction of the information.
Possibilities always lie within trying to prove evidence. Probability is usually the right answer. Probability is that this was a great epic story, not unlike any of the other Greek stories written at about the same time of the bible.
I know your faith is what you rely on for hope, but as an engineer I'm more than sure you have doubts about some of the stories based on the much more vast knowledge that we have today and proof that for people to live more than just 200 years olds is very, very unlikely even with medical assistance.
