text: As far as we know there is no visible life on mars. The reason for this is because mars is inhabitable. The conditions are mars are to harsh for any living organism to be able to live. There have been many expiditons by rovers that have roamed the red planet for years and still have not seen any forms of life. The author states, "There was no alien monument after all." With all this it would be almost impossible for a life form to be able to live on Mars.
