Scientists Pinpoint a Possible “Sweet Spot” for Life’s Origins 4.33 Billion Years Ago
By simulating a billion years of Earth’s history, researchers have identified a possible window for life’s earliest chemistry around 4.33 billion years ago. During its first few hundred million years, Earth was a hostile target. Asteroids, comets, and leftover planetesimals, smaller bodies remaining from planet formation, relentlessly battered the planet, generating intense heat that could [...]
The researchers, simulating a billion years of Earth's history, identified a possible "ideal window" for the emergence of early life chemistry around 4.33 billion years ago. This occurred when the planet had cooled off enough from the bombardment, allowing the delicate molecules of the "RNA World" to form and interact, while hydrothermal systems were created that fueled the probiotic chemistry.

Simulations that reconstructed the environments that dominated the Earth during the turbulent beginning of its existence indicate that rudimentary forms of life would have emerged here relatively early, 4.33 billion years ago. Read more (09/29/2026)
Researchers simulated a billion years of Earth's history and identified a possible window for the most primitive chemistry of life, dating back about 4.33 billion years. The study, published in...
