Life is not the simplest answer because to create life is not simple at all. Think about what it takes to make life at random, from nothing. No, that's not a simple explanation. I don't think there was ever life on Mars and I'm not convinced about water either.Originally Posted by Darwin442002
I think most of what we're seeing is the result of the Martian sandstorms which sweep the planet for months at a time. Planet wide sandstorms never happen here and as a result, I don't think anybody includes them in the options but they do occur on Mars. What a cool planet though.
