If you observe the teeth of herbivorous animals like the cow, goat and sheep, you will find something strikingly similar in all of them. All these animals have a set of flat teeth i.e. suited for herbivorous diet. If you observe the set of teeth of the carnivorous animals like the lion, tiger, or leopard, they all have a set of pointed teeth i.e. suited for a carnivorous diet. If you analyze the set of teeth of humans, you find that they have flat teeth as well as pointed teeth. Thus they have teeth suited for both herbivorous as well as carnivorous food i.e. they are omnivorous. One may ask, if Almighty God wanted humans to have only vegetables, why did He provide us also with pointed teeth? It is logical that He expected us to need and to have both vegetarian as well as non-vegetarian food.
5. Human beings can digest both vegetarian and non-vegetarian food
The digestive system of herbivorous animals can digest only vegetables. The digestive system of carnivorous animals can digest only meat. But the digestive system of humans can digest both vegetarian and non-vegetarian food. If Almighty God wanted us to have only vegetables then why did He give us a digestive system that can digest both vegetarian as well as non-vegetarian food?
