Thoughts of Humanity in the Universe

Had a discussion today about humanity in the universe, and I was thinking... what part do we play in it? what makes us so special? why are we here and so on and so on. in my opinion, i believe that we are just another race in the universe, on a small planet that; to us is huge. i have not really given it too much thought till just recently(this year) because i had that 'human ego' "we are the center of the galaxy and the most important of the 'Races' and we deserve all that we have. Could this be because we are all we know? to understand all of this you need to open up your mind and try to see it from all of the available perspectives; imagination is the first piece to the puzzle. give it some thought, because next time, i will be back with more for more.
