Scientists confirm the discovery of extraterrestrial microbial or biological life before 2035.
Missions to Mars, Europa, and exoplanet atmospheric surveys look for biosignatures. Confirmation requires broad scientific consensus on physical or atmospheric biological evidence.
Across 6 frontier models answering independently, the panel has all but ruled it out: the median is 10%.
They broadly agree, 18 points between GPT at 22% and Claude at 4%.
Nothing is settled until 24 Oct 2036, when the outcome is checked against sources and every number above gets a permanent score.

It hinges on whether a near-term sample or plume measurement yields an unambiguous biosignature that survives contamination tests.
- NASA and partners must first obtain high-quality Mars, Europa, or Enceladus material; Mars sample return is delayed beyond its original schedule.
- Past life-like claims—Viking, ALH84001, phosphine, and possible exoplanet signals—have not reached broad consensus.
- A confirmed inhabited ocean-world plume or multiple independent exoplanet gas disequilibria would sharply raise the odds before 2035.

Mars-sample return plus unambiguous biosignatures, or a smoking-gun atmospheric detection, must occur by ~2034.
- MSR has no firm date and is slipped past 2033; even a 2033 return leaves insufficient time for consensus lab analysis.
- Clipper/JUICE yield only habitability data; no funded Europa/Enceladus lander exists this decade.
- Exoplanet claims (JWST/ELT) carry high false-positive rates; Venus phosphine and K2-18b DMS both collapsed under scrutiny, matching a zero historical confirmation rate.

Turns on whether a biosignature sample or atmospheric detection survives years of skeptical reanalysis by 2035.
- Mars Sample Return has slipped to the 2030s, so any cached Martian biosignature likely misses the window; Europa Clipper reaches Europa in 2030 but cannot sample plumes…
- JWST and future telescopes may flag a biosignature gas, but past 'detections' (Venus phosphine 2020) collapsed within a year under reanalysis, and consensus takes many…
- Base rate for confirmed alien life in any given decade is near zero; this decade sits slightly above only because multiple flagship missions are now funded and en route.

Confirming alien life requires unassailable physical samples or consensus spectroscopy that current 10-year mission timelines cannot deliver.
- Mars Sample Return is delayed past 2035, while Europa Clipper and JUICE will not perform definitive life-detection tests before then.
- Telescopes like JWST or HWO find ambiguous atmospheric gases (e.g. DMS, phosphine) that trigger years of abiotic debates rather than consensus.
- A definitive in situ fossil find by Perseverance or unambiguous technosignature would flip this, but base rates for confirmation remain tiny.

Requires definitive, consensus-confirmed biosignature detection by 2035, a very high bar no mission is positioned to meet.
- Current missions (Mars sample return delays, Europa Clipper arrival ~2030, JWST biosignature hints) only yield ambiguous or suggestive data, not confirmation.
- Past claims (ALH84001, phosphine on Venus, JWST K2-18b) were walked back or disputed after scrutiny, showing consensus confirmation is extremely slow and rare.
- A genuine breakthrough would require new sample-return data, repeated independent verification, and years of peer debate, unlikely to fully resolve within this 9-year…

No mission capable of returning confirmable biosignature evidence is on track to deliver and achieve consensus by 2036.
- Mars Sample Return's revised architecture pushes sample return to late 2030s at earliest; even optimistic timelines leave no margin for analysis and consensus-building.
- Europa Clipper arrives ~2030 but performs only flybys—no lander or life-detection payload is funded or scheduled before 2036.
- JWST could flag a biosignature gas (e.g., on K2-18b), but the leap from anomalous spectrum to 'broad scientific consensus on biological evidence' has no historical…
