	Give the sun a couple of billion of years.  As the sun goes to
red
giant phase, the life-zone should move outward.  If things work out
well, Jupiter's moons could be capable of sustaining life for a couple
of hundred million years if not longer.  More than enough time for life
to start, evolve to sapience and move out amongst the stars when things
get too hot (or too cold when the sun starts to contract).
