Given that we don't really understand how biological processes create such consciousness (if in fact consciousness can be explained as a biological phenomenon), I don't see how we can estimate the chances of it spontaneously evolving elsewhere. It may be that the odds are 1 in 10^100, for all we know. The fact that we know that we exist and are conscious doesn't help because we need consciousness to consider this question in the first place.

exactly! Fermi's paradox makes rather unfounded claims with regards to the probability of life evolving.
