how come I'm here

I wonder 
What makes people 
Born as a bird in a flock of dogs
How come I'm in this place

This is not the place for me to be
This life of mine is made to be in the sky
My drink is air
my home is sky
how can I
survive on land

Can't you see?
Looking at me, can't you see?
I'm of a different kind from everyone here
Look at me
I have a different life
Look at me
I'm made up of something you can't understand
