Seems to me that with a question like this you need to define what you mean by life. For the sake of the discussion, I'll say that I see life as being that which enlivens, creates energy, engenders more life. So that goes way past human life, animal life and even plant life. There's a wonderful architect named Christopher Alexander who has written books and books looking at how buildings and towns engender life.
But anyway, assuming that life is a matter of what we recognize to be living and life giving, then the question is what we are conscious of having life, and is there life beyond that which we recognize as living?
I feel like it is our prime directive to discover the shared being with all that is, that as we move from a sense of otherness to unity with the stranger or strange being in doing this we are really living and engendering life. It's a little obscure, but essentially it's the thesis/antithesis dialectic at work, where the wall between subject/self and object/other breaks down and the two become one. United this way, then all life becomes unified, and sacred.
I have the sense that if we could re-member ourselves completely, all being would be unified past the point of separation and we would simply be. In such a state, there would be no otherness, and past and future would cease to appear real. All would simply be in a completed state of now...
But there seems to be a fascinating wobble in the cosmos which makes us continue to move, change, discover ourselves and become... and this movement around the wobbling lilting center of it all is the thing we call life. It's a sacred dance I believe, and all its parts reflect the whole of the divine.
