But that is a long way from "life bearing", unless the definition of the term considers such compounds as "seeds" that will continue on to form amino acids and such if and when they reach favorable conditions.
If one adheres to such theories anyway, which I do; that is, life is simply a consequence of physical law, albeit the most complex and still largely unexplained one.
The very meaning of life is also too much in the infancy stage to be making conclusions about what is and is not possible. The exobiology studies of silicon based life forms and pathways is already brining into question many assumptions based upon the known life forms. There are likely to be pathways not yet even imagined yet.
