There's a need to be 100% clear about the fact that the idea of remote spectroscopic detection of distant exo-life from Earth's vicinity, results in 100% inference.
It will remain this way until there's a direct correlation established between a verified exo-life discovery, and the verified Habitable Zone parameters in which it is discovered.
Direct spectroscopic detection of HZ Earth-like atmospheric exo-planet gases, from 1000s of Lightyears distant, has not yet been accomplished. JWST is the only instrument I'm aware of that will be capable of directly detecting the atmospheric composition of only the closest exo-planets (presently ~20 Lyrs, or so) .. and this remains to be verified.
