I don't believe that we will discover life any time soon, though I think that it is very likely that life exists elsewhere in the universe. My argument goes something like this:

1. The chances of life arising on any particular planet is very slight
2. But the universe is a huge place.
3. Therefore it is quite likely that life exists beyond earth.
4. But the universe is a huge place.
5. Therefore it is unlikely that any two lifeforms, from different planets will ever meet.

I would be shocked if life was found on Mars (also delighted!). It would mean that the chances of life arising is much higher than I would have expected it to be.

If we were to find life on mars, it would be result in a quantitative change in my worldview, but not a qualitative one!
