Fascinating and quite the accomplishment for humans to discover it.
Indeed, the more I consider it, the more amazing it seems, to the point where it's hard to imagine such a thing common in the Universe.
You know, we sometimes like to speak of "American exceptionalism", for good and justified reasons...
Well, I'd like to suggest "Terran exceptionalism", meaning life on Earth is so improbable as to be almost unique in the Universe -- maybe one in a million stars, maybe one in a billion, maybe even no others.
And that would be my assumption until, until evidence is found proving otherwise.
