An illuminated Earth resting alone in the void of space shows just how secluded and precious our planet truly is. The image exemplifies that although we are most likely not alone in this universe, we are definitely far, far away from other celestial bodies, given the technology that existed in 1968 and also our current means of technology.
Earthrise shows that we are delicate, unique creatures living on a delicate and unique planet. Carl Sagan once said, “Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.” Just as he was commenting on mankind, this idea can also be attributed to the existence of Earth. Though there may be planetary bodies that are similar to ours, Earth is, in the cosmic perspective, precious.
