text: there IS water on Mars.\n\nwe know this because it has polar "ice caps" ( much like the earth )\n\nMars also has a massive canal system that was made by flowing water millions of years ago when it may have been warmer.  no liquid water has been found to date however.\n\nwater principly exists in the solid and gas ( water vapor ) phase on Mars.\n\nNO evidence of life has ever been found to date ( some controversial evidence remains but is not considered remarkable ).\n\nthe recent Mars rovers sent there may yield further clues.\n\nhope it answers your most interesting question.
