yea but that doesn't mean that Earth's configurations are the only ones that yield life. example: the role water plays here on earth might not even be necessary in other chemical/physical systems, or could be played by other chemicals given different gravitational/atmospheric pressures, etc and i don't think there is anything about earth that is unsusual as far as planetary systems go
