We're perfectly evolved for life on earth. Could other life be perfectly suited to live within suns, on planets as far out as Pluto, or in black holes? Why do we say that life "needs water" - isn't it more the case that life on earth needs water, but elsewhere life could evolve to make do with other elements or compounds instead?
