Based upon the above, all the examples you gave of potential life [viruses, self-replicating molecules, etc.] would not qualify. Ditto for the chicken hearts scientists have been keeping alive and pumping these past 60 years. Ditto for stem cells that are multiplying as we speak. However, stem cells were alive when they were freely rearranging themselves as the unique human being they once were (that dull humans could not yet recognize).
