Moons are not planets, they are satellites (that which orbits a planetary body). You obviously didn't read my answer at all. I gave an extremely logical answer. If there is ice, there is water as ICE IS FROZEN WATER PARTICLES. This was my response: "I highly wish there was an "other" choice in the poll. Have you heard of the Drake equation? There is a great video about it by Carl Sagan, look it up. Anyways, the Drake equation estimates how many different forms of intelligent life there are in the universe, or rather any area. I find it far too closeminded to choose definitively, without question, any side at the moment but I am quite convinced that there are other forms of life that aren't on Earth, be it intelligent or not." Sounds logical, doesn't it? Nearly exactly what you said except more accurate -.-. And if we're the smartest lifeform we aren't in trouble, we're safe from being killed by a smarter lifeform -.-.
