Existentialism

The question:
Nothing I do today - or in my whole life, for that matter - will impact the fact that in five billion years the sun will have exploded, no one will have remembered who I was, and the Earth will be gone, most likely with the human race in its entirety. So why do I choose to do what I do? Why do I choose to engage in these petty situations that we oft find ourselves in? What difference does it make if we all die right now, in this vast, open universe where all any of us are is an extremely minute creation of carbon on a blue speck?

My answer:
I do what I do because I am alive. I care about people, and money, and grades, because I am alive. While I am alive, even though I do not matter, I will care, because what else is there to do? There is nothing more to life than living, just as the universe is being. I do what I do because of the structure of my brain, and so does everyone else. Even if we are just a coincidental occurrence in a tiny part of the universe, I must live because it is all I can do.

Thank you for listening to my mildly pretentious rambling.
