[Who] A Planet 124 Light-Years Away Just Sent a 99.7% Life Signal

In April 2025, the James Webb Space Telescope detected dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in the atmosphere of exoplanet K2-18b, 124 light-years from Earth.
Confidence level: 99.7%.
On Earth, only living organisms produce this molecule in large quantities.
But science demands 99.99994% (5 sigma) to declare a discovery.
Can the remaining 0.29994% be closed?
NASA's reanalysis showed that 87.5% of models failed to reproduce the DMS signal.
The results of additional observations in 2026 could answer the greatest question in human history.
