You're right the methane could be primordial.

Methane only has to be replenished when it is present in the atmosphere of a body like Mars or Titan.
When it is subsurface such as on Enceladus it could stem from the early origins of the solar system.

        Titan's CH4 is probably primordial as well. - et - 3/13/2006 7:38:43 PM
        
        It's good to be conservative & cautious with interpretation, but a biological explanation is still feasible. (n/t) - Jacob Samorodin - 3/14/2006 12:27:36 AM
