Life Emerged Almost Immediately

The essay argues early Earth was not a long, sterilized 'hellscape' and that life arose within mere millions of years after the planet solidified. If true, abiogenesis is fast and robust given suitable environments, not a rare, slow fluke. — This shifts Great Filter reasoning and strengthens the case for aggressive biosignature searches and astrobiology funding because life may be common where conditions are right.

The author writes that 'life formed quickly after the planet solidified – perhaps astonishingly quickly,' challenging the slow-chance narrative.

And Then There Were Two?

The article reports ~3σ JWST detections of DMS/DMDS at ~10 ppm on K2‑18b, a Hycean world, suggesting non‑oxygenic life might be common. Evidence for a second biosphere would strongly support the view that life arises readily given suitable conditions, tightening Great Filter reasoning and boosting astrobiology searches.
