Liquid water is sufficient for any form of life, or at least for life as we know it. If there is water ice on Mars, then there's a good chance that liquid water is or was there too, which increases the chances that there was or maybe still is life on Mars.
And if theres life on two separate planets right next to each other there's a huge chance that there's live on many other planets too.
