    The Earth would no longer be apt to be hit by a comet if there weren’t any.  This is probably the biggest difference that would take effect, and not necessrily a bad one for us humans, as some people are fearful of this happening.  Some astronomers believe that comets impacts brought the arrival of water on Earth, which may in turn have caused life to commence here.
