Yes, life vs . non-life exists on a continuum. Alot, of this is just a rehash of the pro-life right to life debate and why it will always be debated. It's pretty hard to make a black and white distinction between something being "just a bunch of cells" or being a live human. On the other hand there are always pretty clear instances of when we can say something isn't alive - a rock, or something is alive - you sitting there typing.
This alive debate vs. not-alive debated started I think because of consciousness being the distinguishing element between an alive human and a dead one. But, the question then is, is consciousness necessary for life? And, if so, do all living things have consciousness? I think most people would agree that consciousness isn't necessary for life, and that all life forms are not conscious. So for me the really big question is why is there consciousness at all?
