      I don’t think it is possible for a human to live on another planet if there is no oxygen available in the atmosphere or if you do not wear a space suit which continually provides oxygen.

      If we sent a mission to another planet, it may be possible to develop oxygen from other chemicals such as carbon dioxide or methanol or water or something. This could then be used to allow us to breathe, however, this would require considerable energy.

      It may also be possible to find another planet with an oxygen containing atmosphere. Then providing the other gases were correctly balanced and there was no other poisonous stuff, you should theoretically be able to breathe it…
