       | Perhaps. If it does, it probably couldn't be past a certain
       | depth. The deepest man-made hole was about 12km, and reached
       | roughly 180C at that depth. That's well beyond what even the most
       | durable hyperthermophile organisms can withstand, to speak
       | nothing of what the pressure would be like at greater depths.

         | Every time we assume a limitation like this we've been wrong.
         | If tardigrades can survive floating through space, I think it's
         | reasonable to guess that there might be life that survives at
         | the other extreme.

       | Do we know anything about the occasional Methane emissions I
       | heard about on Mars?

         | There have been cases where we believe we've seen ice form in
         | rover tracks, hinting at water just below the surface.

       | From what i read, this post doesnt announce we've found some
       | crazy extremophile unicellular microbe. Just that there is
       | evidence to suggest they are there (due to the chemical makeup of
       | soil/boreholes).
