Why man thinks they are grater than Animals??

That's a big problem to me.
When I'm with lots of humans I can't feel different between animals.
Affinities.......

1. They also shouts as birds.
2.Sometimes they get ready to fight with each others like bulls.
3.They spread bad smells like civet cats.
