Regarding your point on "following the liquid": I've heard (from threads over in r/askscience, I don't have any official sources) that one of the things we're looking for isn't just liquid, but an molecule that can exist as a liquid, solid, and gas on the same planet, like water does on Earth. Is this something that you guys look for, or am I completely out of line and you guys basically just look for water?
