Someone once said, I forget who, that “we are either alone or we are not, both options are equally terrifying.” I’d like to propose a corollary to that, while they may be equally terrifying, the implications of both, especially when taking into regard the Great Filter hypothesis, are markedly different from each other.
If we are alone that’s arguably good, but still terrifying, news, because it means we have past the Great Filter that so many other would be civilizations have failed to pass through, we essentially have the entire universe to ourselves, and will not only survive, but thrive, perhaps even become as gods, but the implications of what it means to be alone are still vast. I dare not explore them.
If we are *not* alone, that’s bad, and still terrifying, news, because it means we have *not* passed the Great Filter, then, and we don’t have the universe to ourselves. It means that the path to a toolmaking and spacefaring civilization is an easy one, and that the Great Filter lies beyond the point at which life arises.
If we discover extraterrestrial microbes, that’s bad news, if we discover complex extraterrestrial life that’s even worse news, if we discover extraterrestrial toolmaking intelligences that’s a death sentence for ourselves and them.
Let us pray we do not discover alien life any time soon, however, the likelihood of alien life existing is, as a recent study showed, statistically inevitable, so we may be doomed after all.
