In this article, it is argued that several habitability conditions (in fact, at least seven such conditions) appear to be fulfilled automatically on the circumbinary planets of main-sequence stars (CBP-MS), whereas on the Earth these conditions are fulfilled only by chance. Therefore, it looks natural that most of the production of replicating biopolymers in the Galaxy is concentrated on CBP-MS of particular classes, and life on Earth is an outlier, in this sense. In this scenario, Lathe’s (2004) mechanism for the PCR-kind (polymerase chain reaction) tidal abiogenesis on the Earth is favoured as generic for CBP-MS. Unsolved problems of the scenario are also discussed.
