ANN and OT: Calling All SETI Enthusiasts

The weather is so nice here, it's hard to resist a good off-topic blether (discussion).

There is another argument that says we can't make any reasonable assumptions about the likelihood of life elsewhere until we know more about the "normality" of the origins of life here. At the moment, the origin of life on earth is unknown. So we can't say how improbable the event was. If it were discovered that it was an extremely unlikely event, then we might revise downwards our estimation of the chances of finding life elsewhere. And the opposite also applies. Until that time, aren't we just guessing?

No harm in looking though.
