Why do we keep on going!?

Question:

Why do we keep on going!?

We are NOTHING in the universe, i know i'm sounding suicidal but everyone is going to die in less than a hundred years, for all we know Earth is the only planet in the universe that has life, and i just marvel at how people just keep on going. but why do we bother, is it so that we can make the human race better or is it simply to pay the bills?
