Man were created in God's image.
Humans are at the top of the food chain.
We are capable of thoughts and decision makings.
We use tools.
We create things.
We have souls.
We have societies and family.
We can think of consequences of our action.
We can read and write.
We know whats right and wrong.
We create math, science, art ,music, etc...

there are many ways to think that we are superior than animals...
so think about what makes you different to other animals..
hope it helps.. :)
