And we've sent probes out farther than Pluto! If, out of the hundreds of billions of star systems in each of the hundreds of billions of galaxies in our universe, we can't find exolife by the time we get to the edge of our own little solar system with probes that couldn't detect life unless they bounced off of it, we get to say 'no sign of any life, outside of Earth, anywhere in the universe so far' as if we've nearly exhausted all of the possibilities already instead of only barely starting to make the first eyeblink of an exploration into the possibility of life on other planets. There's literally no way to know the odds of life on a given earth-like planet with only one to extrapolate from. We know it's possible. That's all we know for sure about it. Is it so unlikely that it probably only happened once in the whole universe? Conceivably, but for all we know, it could also happen on every world with liquid water.
