If life exists on Mars, it is most likely to be in the form of bacteria buried deep in the planet's permafrost or lichens growing within rocks, say scientists from NASA.

The prevailing view has been that planets mostly accumulate water only long after they form: If a young planet with water trapped in its rocks collides with another heavenly body or even large debris — common occurrences in the cosmos — the impact would, presumably, drive accumulated water into space, leaving many planets bone - dry.
