It’s interesting but I think if we’re talking about life on other planets, why do they necessarily need water? Different life forms could adapt to different living conditions…like we did….Not that anyone has said anything to imply this, but a lot of the time it seems like its implied that if there is no water somewhere, there is no life. I don’t think that’s necessarily true. Well, really, I have no idea like everybody else, but I don’t think that water = life, and I also dont think that no water = no life.
