it's so true - we are both so small in the grand scheme of
   things (humans exist for such a short time in history) and earth

   "intelligent" life in the universe so far (maybe we'll find
   someone else someday) - and if you believe in quantum mechanics
   then you may believe that observing actually changes things -
   then we REALLY are significant, while being insignificant at the
   same time. keeps you humble -and- proud at the same time. Yes -
