Could you point me at where this is called biocentrism? I was confused because neither sense of the term at http://en.wikipedia.org/wiki/Biocentrism seems to require uniqueness.When I say "biocentrism" I'm specifically referring to the idea that of all the planets in the universe, abiogenesis only occurred on Earth.
It is a term introduced here (page 204): I believe the point of introducing this term is for philosophical discussion on the current state of astrobiology. I think it is a useful and necessary term when discussing life in the universe. I can understand if some think the term is unnecessary.Biocentrism continues to hold in the sense that, even if most scientists subjectively believe the existence of extraterrestrial life is highly probable, we still haven't proved it yet.
