    methane doesn't have an odor, you linked to the data sheet of trichlorofluoromethane, a completely different molecule

    The gas in your house is artificially made stinky so that people would notice leaks and blow their house up, which happened a lot back when the stinky chemicals weren't added and it was odorless
