[Extraterrestrials] may have progressed from biological species, which are fragile shells for the mind at best, into immortal machine entities and then, over innumerable eons, they could emerge from the chrysalis of matter transformed into beings of pure energy and spirit. Their potentialities would be limitless and their intelligence ungraspable by humans. These beings would be gods to the billions of less advanced races in the universe, just as man would appear a god to an ant.
They would be incomprehensible to us except as gods; and if the tendrils of their consciousness ever brushed men’s minds, it is only the hand of god we could grasp as an explanation. Mere speculation on the possibility of their existence is sufficiently overwhelming, without trying to decipher their motives. The important point is that all the standard attributes assigned to god in our history could equally well be the characteristics of biological entities who, billions of years ago, were at a stage of development similar to man’s own and evolved into something as remote from man as man is remote from the primordial ooze from which he first emerged.
