Indeed! Thomas Gold's "deep, hot biosphere"

The deep, hot biosphere

suggests that one needs to dig down a ways.  Also, I would bring to
your attention that the chemosynthesis of the DHB involves no
sunlight.  Needing an energy source pre-photosynthesis, the current
theory of life's origins looks favorably at black smokers as a
candidate site for where life on Earth "booted up".  Panspermia -- a
sort of planetary transfection -- is an alternate mechanism for how it
got started  here on here.

We live on the surface of our world, and perhaps have a bit of bias
regarding life as something that happens on the surface.  But it
occurred to me that core heating creates a temperature profile from
core center to the outer reaches of any atmosphere.  Somewhere along
that profile it would be cozy warm.   So any planet anywhere -- Pluto,
or even an interstellar wanderer in the dark emptiness between the
stars -- could harbor life.  Don't need no steenkeen star, just an
insulating over-layer of dirt or frozen atmosphere.

Best, Jeff Davis
