BBC TV Horizon had a 60 mins documentary on the chaotic origins of the
Solar System about three weeks ago. It is still watchable /

The wandering Jupiter theory sounds pretty dramatic.
But whether this is essential for life creation is another question.
This universe seems to be 'designed' for life creation so that
primitive life appears wherever there is a chance. Advancing to
intelligent life may well require another chain of unlikely events,
but the universe is a pretty big place............
