The simple but unsatisfying answer is that life is simply something that happens as a consequence of laws and initial conditions of the universe, like galaxies or the structure of the water molecule. In that reductionist view life doesn't have any meaning or purpose to the universe as a whole. it just happened. That raises the question, what is the meaning our purpose of our human life in particular, but that's a whole 'nother discussion.
A related question is, what is consciousness to the universe? It's harder to see how self-awareness and free will could be a consequence a purely physical processes. Which leads to the next question, does free will even exist? I think it does, but I'm at a complete loss as to how it can be possible. Or this, is consciousness a necessary condition for free will, or vice versa, or neither?
Can anyone smarter than me (which is probably most of you) comment on this?
