      More and more planets are being discovered all the time. I’m sure there are lots more to be found and as we learn better ways of looking for them we’ll see lots more.
      Life could start on many planets, but we don’t know how likely it is to start, so the answer is we don’t know. Even if there is life out there it would have to be in a form that we could recognise (or could recognise us!). I suspect that there is life out there, but I think it is unlikely we’ll ever meet it.

      David is the expert in this field. I suspect it might also depend on what you think ‘life’ is!
