If you ask me, all the planets had life or will have life at one point. It goes in a circle, one planet gets destroyed, another one starts to have life and so on. One day life on planet Earth will be destroyed and a new one will start to grown. Every planet will have a chance to heal and start over. That is IMHO
"If you ask me, all the planets had life or will have life at one point"
Mercury never could have supported life.
Saturn, Neptune, Urinas, also planets which are highly unlikely support life without some level of human interference on a grand scale (mainly on their moons)
Jupiter COULD support life on its aqua moon, if it is like what we think it is. And Mars has no magnetic field, even when the sun gets hot enough to warm the planet, its core is dead. Once more, without human interference that world will not properly support life.
