The appropriate gases must be present in sufficiant quantities; the necessary temperature must be constant (or at least mild enough). I realize that not all life is the same, and that theoretically there could be other ways of creating life from different elements and environments. My point still stands, however, that not all-- or even half-- of all of the planets in the Universe would be able to begin or support life.
