Another comment -

Brian Koberlein points out that even if other star systems usually
have their gas giants closer to the sun than Jupiter and Saturn they
probably also have rocky moons which could be similar to earth.
So the the gas giants being nearer to the sun might not have too bad
an effect on getting life started.
