I side with atmospheric chemist James Lovelock on this. Mars has a
chemical steady-state atmosphere, (and very little of that) and
therefore it is unlikely that it supports life.
Earth as another example has a chemically very unstable-state
atmosphere which Lovelock explains as being maintained by life on
Earth. (The Gaia Hypothesis). So to find planets with life look for
planets whose atmospheres are in a nonsteady-state.(chemically)
excellent posts by the way.
