Humanity discovers verified extraterrestrial life before 2035.
A central question in astrobiology is whether alien life exists. Confirmation would require peer-reviewed consensus and official scientific or governmental verification.
Across 6 frontier models answering independently, the panel has all but ruled it out: the median is 7%.
They broadly agree, 15 points between GPT at 19% and Claude at 4%.
Nothing is settled until 4 Nov 2036, when the outcome is checked against sources and every number above gets a permanent score.

The odds hinge on whether sample-return, ocean-world, or exoplanet evidence crosses a very high false-positive bar.
- NASA, ESA, China, and telescope teams must obtain reproducible biosignatures and independent confirmation before late 2036.
- Past claims—from Viking to phosphine on Venus—have not survived consensus, making decade-scale confirmation historically rare.
- A returned Mars or ocean-world sample with unambiguous cells or metabolism would sharply raise the estimate.

Mars sample-return or in-situ data must yield unambiguous biology that survives peer review by end-2034.
- NASA/ESA MSR is already slipping; even a 2033 Earth return leaves insufficient time for analysis plus consensus.
- JWST/ELT atmospheric features historically get abiotic explanations first; remote claims never reach official verification.
- Zero confirmed detections in 60 years of searches; only a replicating microbe or fossil would invert the base rate.

Turns on whether ambiguous exoplanet atmospheric biosignatures or Mars samples achieve rigorous, undisputed scientific consensus.
- JWST and future surveys detect possible biosignatures, but proving non-biological origins impossible takes years of intense debate.
- Mars Sample Return will not return cached cores to Earth before 2035 under current NASA and ESA budget and mission timelines.
- Unambiguous narrowband radio technosignatures verified across multiple observatories remain the fastest route to high-confidence proof.

This turns on whether a biosignature is confirmed and replicated by 2035, not just detected.
- No detection in 60+ years of SETI, and Mars sample return slips to the 2030s, so the pipeline is slow.
- JWST and Europa Clipper can flag biosignatures by 2030, but peer review plus NASA/ESA confirmation takes years.
- A confirmed signal or fossil would need replication by independent teams before 2035, which is the bottleneck.

Hinges on a biosignature or sample result surviving years of peer review and consensus before 2036.
- Current missions (Mars sample return delays, JWST exoplanet spectra, Europa Clipper) could yield suggestive but not conclusive evidence by 2035.
- Verified discovery requires reproducibility and broad scientific consensus, a bar no prior claim (e.g., ALH84001, Venus phosphine) has cleared.
- A definitive biosignature detection with independent confirmation within the next decade would be the game-changer, but nothing currently points that way.

No mission in this window can both reach a life-bearing environment and return consensus-grade evidence.
- Mars Sample Return is delayed past 2035 and faces possible cancellation; Europa Clipper arrives 2030 but only does flybys, no landing.
- JWST could detect an atmospheric biosignature, but going from anomalous spectrum to 'verified life' with peer-reviewed consensus in under 9 years has no precedent.
- In the entire history of astrobiology, zero confirmed detections; even the most optimistic roadmap (Enceladus lander, Mars return) pushes past 2035.
