Actually, humans are counted as animals, humans aren't the main living things on earth. Humans are mammals, just like the other breathing, furry, animals out there.
Animals don't enjoy attacking humans. Most of the time they attack out of defense or hunger.
They want to know what it is like to cross animals.
We do not know. Humans are animals (we like to think of ourselves as 'higher animals').... but we don't know whether other animals have a spirit or 'emotional being'.
Yes.
they grow like humans and animals
No, they can't.
