I believe that life is probably rampant throughout the universe and that wherever it can possibly exist, it probably does, and that if/when we ever breakout and make it to outer space we will wonder at the diversity and often not even recognize some manifestations as living organisms And yet, what if the Earth is the one and only? Just suppose the creationist with their nutty analogies of a blind man finding one red ping-pong ball among zillions of white ones covering the entire surface of the world six feet deep is accurate... That of the zillions of planets that must exist, ours is the red ping-pong ball... In Star Trek lore there is an original pro-generating earlier race of humanoids who gave rise to Earthmen, Klingons, Romulans alike. What if we, here and now are that pro-generating earlier race? Wouldn't that be a huge responsibility? Doesn't it make you want to cherish and foster life on Earth? If just twenty generations ahead every human is related to any one of us who is alive today, are we not all as great as Abraham, patriarchs and matriarchs of our future space-faring descendants? Although I am taking it out of context, this concept reminds me of the final line of Henry David Thoreau's Walden: There is more day to dawn. The sun is but a morning star.
