It is inconceivable that a judicious observer from another solar system
would see in our species -- which has tended to be cruel, destructive,
wasteful, and irrational -- the crown and apex of cosmic evolution.
Viewing us as the culmination of *anything* is grotesque; viewing us
as a transitional species makes more sense -- and gives us more hope.
