The farther we travel, the more life bearing worlds we find.  The difficult thing is actually exploring all of the star systems now within a year’s travel of Earth.  No single government has sent ships to every star in that range.  There are too many stars, and too few ships to do it.  Private surveyors are the only visitors to many stars, selling their data to the mapmakers.  Some stars haven’t even seen that much of us.
