Have you ever thought about why we come to this world??

I have always wondered why I am here as the way I am - why not a bird, a fish, or a tree? but a human, a girl...

should we consider ourselves the highest species of the world?

or are we just like ants to other higher consious beings - the way we have limited senses like ants to them - tat they can detect, observe our behaviours like we do to ants but not the other way round...
