See Charley Lineweaver's recent paper (arXiv:astro-ph/0209385) for a
discussion of how likely life is to arise on a terrestrial planet. Of
course the issue of how many terrestrial planets is not covered there,
although Lineweaver has some arguments for that as well. I would not
be surprised if life is common in the universe.

However, see Robin Hanson's paper (
for an argument as to why intelligent life might be rare.
