"It's life Jim, but not as we know it". Why d we obsess with looking for water worlds and goldilocks zones? Sure, be nice to find life as we know it, but even Extremophile Bacteria found on Earth go part way to dispelling the need to find life as we ACCEPT it. Who's to say the first life form we find does not paddle around in the liquid hydrocarbon lakes of Titan?
Life will be found, and sooner than 20 years I think. I believe the seasonal variations in Martian methane levels in the atmosphere is POSSIBLY bacterial in origin. Time will tell.
