How do you define "life?" Scientifically, life is defined as requiring specific physical aspects, including

1) Response to stimuli
2) Reproduction
3) Consumption of nutrients
4) Regulation of internal environment
5) Ability to grow

Rocks, water, what-have-you have none of these physical processes. Atoms don't reproduce, nor can they actually respond to stimuli. Water doesn't consume nutrients. These things just ARE.

There's also another definition, that I particularly like - that life is defined by the ability to reduce its own entropy. I should also note that trees have been considered living things for a loooong time; there's never been any question that they are alive in their own weird way.

Now, John McCain, that's a mystery I don't think science can ever solve.
