Given the size of the universe[1], believing there's only one planet hosting biologically evolved organisms, falls a bit short IMHO. That said, it won't change anything knowing there's no one else out there. Actually it would be a little bit frustrating because it would mean that there's nothing more to discover... Biologists might feel limited on this planet alone.
