Define life

Just wondering about /sci/'s definition of life. None of that made of cells bullcrap. Bonus points for answers which adequately handle fire, viruses, corporations, and artificial intelligence.

Best answer will recieve a box containing a simulation of a universe whose denizens are just on the verge of discovering that their world is a simulation.

Galaxies don't evolve. Make sure you know what evolution means.
I'll give the old story distinguishing organizational ideas against a grouping of matter.
There is a foreigner (it's kind of an old story, so go with it) who visits Britain or America (or some industrialized nation), and decides to go and visit one of these universities he's heard so much about. Yet, when he gets there he only sees a group of buildings. He asks a faculty member which building is the university, to which the faculty member responds that they all are, as well as the people who work there and attend there. This confuses the foreigner, who wonders how such a large and dynamic group of things can be the university. The worker then explains why, and describes several other institutions, such as governments, clubs, teams, and so on. (If you can't tell, I got lazy, just look up organizations in wikipedia or something).

I must admit, you blew my mind when you asked whether or not life must be composed of matter, although, I can't really think of how energy could replicate or evolve, or even exist as a functioning system.
