However, I must caution you that we don't know the
odds against some kind(s) of "life" appearing somewhere
in the universe. Clearly, _intelligent life_ is quite
rare. As Enrico Fermi once said, "if intelligent life is
so commonplace, where are they?" Nevertheless, this
does not completely rule out the possibility that
bacteria-like organisms are probable ... (yet)
see for example

I think this article has a fairly well balanced view
on the matter.
By Grace we proceed,

The article you quote, Crawford I., "Where Are They?" Scientific
American (July 2000), pp.28-33, is subtitled "Maybe we are alone in the
galaxy after all", but has a sidebar by LePage A.J., "Where They Could
Hide", pp.30-31.
Another article, Franck S., Block A., von Bloh W., Bounama C., Garrido
I., Schellnhuber H.J., "Planetary habitability: is Earth commonplace in
the Milky Way?", Naturwissenschaften (2001), 88:416-426, derives a
"thoroughly educated guess that there should exist half a million Gaias
(i.e. extra-solar terrestrial planets with a globally acting biosphere)
in the Milky Way."
Compare this with the estimate by Ross H., "Big Bang Refined by Fire"
(Pasadena, CA: Reasons to Believe, 1998), p.27, that the probability of
finding, in the entire universe, a single planet suitable for human life
is about 10^-77 (plus or minus a few orders of magnitude).
Here we have another sample of one, with the second one never observed
(up to now)! Educated guesses about its probability seem to be fraught
with pitfalls. I have the impression Hugh Ross is closer to the truth.
God is able to produce events of negligible probability. Did he use
"hidden options" to guide the process?
