Atoms are so small, and there would have been so many niches way back then, I could see life on earth being close to inevitable.
If there is (or was) even just some interesting chemistry on Mars, or Europa, or Enceladus it would lend credence to England's idea.
Conversely, in my view, the Kepler satellite is showing many, many unanticipated ways a planetary system can turn out (from a soft squishy life form like me's perspective) bad.
(granted,Kepler can't 'see' solar systems like ours, and the planet statistical work isn't done yet, so I might be a little pessimistic here)
