Yes, that's largely what this thread is about: recent discoveries support the idea ET life could exist, but it's not proven.

The intent of LiS, as I understand its charter, is to discuss the ways we're searching for ET, mostly by trying to locate environments (both actual and hypothetical) that might be habitable, perhaps only by some extremiphile, with perhaps a little (clearly marked) fanBAUTer speculation to tide us over between missions.
Luckmeister's statements seem contradictory to me.
He says, "As to the OP title statement -- there is no mounting evidence for ET. There are however recent findings that Earth life is more tenacious than previously thought, which allows us to "speculate" that chances of survival of life elsewhere, once it has begun, may be higher than we previously assumed."
So ... "recent findings" (eg. extremophiles; potentially habitable Mars, Titan, Europa; feasible alternate chemistries; exponentially increased numbers of stars and potentially habitable bodies around them; etc.) would not be considered "mounting evidence" which make it seem more likely life exists elsewhere?
I don't see the difference.
It almost strikes me as double speak.
Where the telescope ends, the microscope begins. Which of the two has the greater view?
