Even humble life on it's moons, living with ammonia in it's blood or something, as they found on titan. Lakes of methane, with methane rain replete with lightning. Volcanic eruptions of water mixed with ammonia that kept it from freezing and had it in a semi solid molten state at -200 degrees f or whatever it is. From the probe landed there, forget when that was, on titan. But life could exist even there, even if not higher life, they do have liquid bodies. That is the factor for life, the right liquid to gas temperature changes with the right chemical reactions, and the spar of zeus.
