EDIT: Just to make things clear, I'm not saying that God does not exist, but what I'm saying is that the system derived from that belief (i.e. religion) is very much created by humans and for humans.
"In three cases meat may not be eaten by a monk if he has : (1) seen (2) heard, or (3) suspected that the meat has been especially acquired for him by killing an animal (i.e. the animal has been killed specifically for the monk). This rule is called the Rule of Tikotiparisuddha (Pure in Three Ways).
However, the meat of the following ten beings is forbidden to be eaten by the monks : human, elephant, horse, dog, snake, lion, tiger, leopard, bear, and hyena. (Vinaya, Mahavagga, Book 4)"
