According to the Bible before there was sin and death all Animals and Humans were herbivores.
Genesis 1:30 "And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat: and it was so."
Recently an atheist said to me:
Many modern animals, as well as many ancient ones, have mouths and digestive systems which are not only completely incapable of making use of [vegetation], but are specifically designed* to kill prey and digest meat.
You are making wild assumptions very prevalent to the modern mindset. You aren't the first I have heard this from. Just because an animal has sharp teeth doesn't mean it eats meat, it just means it has sharp teeth. In fact you need sharp teeth to eat certain vegetables.
Look how sharp the teeth are of the Panda and they eat bamboo.
How about this savage animal that flies around and ferociously rips into...fruit, called the fruit bat. Yet it's classified as a ‘carnivore’?
The polar bear is the most carnivorous North American bear and has a digestive system that screams for seal. In the wild, polar bears live an average of 15 to 18 years, in captivity though, they may live as high as 40. In captivity their diet consists of some read meat but also Lettuce, Apples, Oranges, Broccoli, Sweet Potato's, Celery, Tomatoes, Grapes, Watermelon, Rock melon, Barley, Cracked Corn, Cod Liver Oil, Carrots. And they digest all of it quite well.
Now this is an intelligent and witty atheist. This man can grasp the concepts of reality quite well, but it's the presuppositions that he holds so closely that get's his mind stuck when the evidence is in front of him. So the misconceptions and wild assumption is the problem and is what's happening these days. The evidence MUST fit their tiny little evolution box no matter what data pores out of the sides and onto the lab floor. At least at the end of the day they have their little box with big teeth.
