(5,323 posts)we are the only intelligent life??
It is worth keeping in mind that the vastness of the universe is only one-half of the equation. We know now that there are almost certainly many planets in our galaxy, let alone the universe, that are suitable habitats for the formation of life. But, the other half of the equation has to do with the probability of life, and especially for purposes of this discussion intelligent life, developing on any of these habitats. The answer is that we have no idea other than the probability lies somewhere between 0 and 1. If the actual probability is close to one, then yes, the galaxy or universe likely teems with life, OTOH if the probability is close to zero, then the possibility is very low and possibly so low that no intelligent life other than our own exists, at least at the current time, in our galaxy or, beyond.
IOWs, the probability of life other than on planet Earth remains a completely open question.
