there are valleys which where formed by stong rivers-when there was and believe it or not, mars has blizzards every day. snow means water. only thing is water freezes in space so there will never be any water on mars

They don't for certain. There are signs though, including geographical features seen from the air that look like water-carved features on Earth. Mars also has light clouds, and the northern polar cap (I believe) is mostly water ice.
