Does this also  mean that actual life exists on Mars? Yes, but not the complex life form that we have today the life forms discovered on Mars were microscopic organisms and bacteria. Your probably wondering how exactly did Astronomers find water (H20) on Mars? NASA's robot  (named Curiosity) has found
