Like in another topic you like to deviate the original topic to talk semantics just to prove your point, when semantics is not the point here.
Even though, technically speaking probability alone (unless 100%) is never correct by itself, you still need factual confirmation, I understand your point and I agree it's possible intelligent alien life exists.
However still, possible, not certain. And why that matters for this case? Because there's a huge difference between worry about intelligent aliens invading the planet, when there are humans right now destroying the planet. One could live in a bunker worrying about alien invasion or instead try to make a difference about things we know exist for sure.
