The example that I used then was to ask which is more complex Titan which is
random
molecular interactions with probably some organic molecules thrown in or
the Earth where there are living self-organising entities. The answer I
would say is the Earth. It is not likely that a piece of Titan will leave
the moon visit another moon and return to Titan. That kind of behaviour,
made even more "complex" due to the motivations underlying such behavour.
