“Some primary reasons that both Plato and Aristotle had for believing in God were utterly erroneous—simple errors caused by our being stuck to the planet and misled by the sensation that the planet is standing still. If they had been aware that the Earth spins, they would have understood that, by and large, we are making our own light show in the night sky. As it was, the precision of the movements of all the stars seemed astonishing. If we knew how we lined up among the planets, their motion would not seem so strange and willful. Also, had the philosophers been able to leave planet Earth for a jaunt in outer space, they could have seen that, at a distance from gravity and atmosphere, moving things tend to keep moving, without any need for an impelling force. From out there, the motion of the planets would seem natural as well.”
