I agree that life is not very likely. We appear to have gotten lucky. Aka, “the rare earth hypothesis.” As far as habitable zones, both Mars and Venus are in the habitable zone of our solar system, and they appear to be barren.
But do not despair! A new approach has been identified. Look much wider and farther, and as opposed to biosignatures, we should look for signs of technosignatures. This would be much harder to mistake for natural chemical processes.

Technosignatures in general seem to be a good idea to satiate our curiosity.
