Ok, so there is a mission to Europa, your on it, and you arrive, and you meet intelligent aliens that speak every langauge (Somehow) what would you say to them?
Yes, that is a valid point, but what if the Earth was falling torward an impending doom that was unstoppable? what planet or moon would you choose for 'Relocation' of the human race?
We all should know Kepler 425-b and Gliese 581d, and many more, but would do you think would be the best candidate? Planet? Moon?
What do you think?
My personal opinion is on Gliese 581 g.
