Exoplanets Extraterrestrial life Intelligent Design

Rob Sheldon: Don’t give up all ET hope due to recent exoplanet disappointment

Sheldon: … in our own solar system, Saturn is far outside the “Goldilocks Zone” yet it has a moon, Enceladus, that is emitting steam jets filled with hydrocarbons. … The danger of being overly-quantitative is not just the overreliance on models, or the higher risk of failure, but rather the real probability that “certainty” blinds one from observing the actual phenomenon.

Faint hopes easily revived! “Life may be evolving” on closest exoplanet

The fundamental problem is still the same: It is very difficult to extrapolate from a sample of one instance of life. Suppose we had information on tens of thousands of exoplanets, thousands of which had life. Making the reasonable assumption that a pattern develops within this data, we could then give fairly reliable odds on a given planet having life if its relevant data are known. But we don’t have any of this. It’s all a dreamscape.
