Re: are we alone in the universe?

I dont understand the assertion that the question of the extent of life spread through the universe is a matter of metaphysics?

We have no problem clearly defining what is alive here on earth, and what is not 'life'. Why should there be any difficulty determining the probability of finding life elsewhere, based on what we already know.

Is their any question of whether we have found life on the moon, venus, mars, jupiter? is there any question of whether we can reasonably expect to find life on the sun?

Life interacts with the physical world in a well established manner. When does the search for life stop being a matter of physics and probability, and start becoming a matter of philosophy or metaphysics? When does it stop being hard-core science? when we get to the nearest star? the next one after that? 100 light years away?

Im speaking of life as we know it: physical organismism that interact with the physical world.
