True as far as we know

I still wish I knew what was going on behind the scenes... What with all the hero name changes. We used to have heroes called Skeleton King, Necrolyte, and Windrunner, and then suddenly they start changing the names to Wraith King, Necrophos, and Windranger? There's no way that legal teams weren't involved somehow...

Just because they're life-habitable doesn't make them human habitable. (Life can exist at extreme pressures at thermal vents at the bottom of earth's oceans, while a human would implode there)

If life exists on Europa for instance, it might be in the oceans under a very thick layer of ice. Europa doesn't have an atmosphere, and humans need breathable air. (that being said, I doubt we could terraform Europa to have a breathable atmosphere, I don't think it has the gravity to hold onto one)
