I think we ought to also remember that the definition of life is itself based on the biology of Earth's organisms. Who's to say what's life and what isn't?
Although, once again, I'm making a statement I disagree with. I would hold that "life" is any chemical reaction that self-sustains and does not "wind down". Simultaneously, objects which reproduce and are subject to natural selection should also be considered.
