Well, the animals clearly aren't immortal like man was. When man sinned, God cursed the earth. Thorns and thistles apparently weren't part of the original design. The animals aren't at the same level as man. God told Noah the animals were for food. Jesus, Himself, served other's fish and requested meat.
The animals aren't fallen, they were never created to be at a state where they could sin or fall from. They're food.
I don't know how you can come out with this stuff. Have you ever shared your life with a dog? Or been in the water with a dolphin? Or built up a bond with a horse? I have done all of those things, and I can tell you that these creatures have recognisable personalities at least the equivalent of a small child (should that be "animalities"?). Dogs and horses are well capable of showing remorse for bad behavior and fear of the unknown. Look into the eyes of a chimp and tell me that it is "just food".
Get your head up out your Holy Book and look at the real world around you!
Right, so why would God create them with a design deficiency?
This is evidence that evolution is correct and creationism isn't.
