Homo Sapiens are unique as life on Terra, that due to our self-awareness, we have become colossally arrogant, so wrapped up in our self-importance that we forget our place. Homo Sapien is merely one sub-link in an unimaginably long and complex history of life. One day, the last of the homo sapiens will expire, and Terra will continue to spin, utterly uncaring of our brief existence.
Our utter insignificance in the universe as a whole is undeniable evidence of our natural evolution. We started from nothing, and one day, we will return back to nothing.
