What Was Earth Like 1.5 Billion Years Ago? | Documentary for Sleep

Drift back in time 1.5 billion years — to a silent, alien world before complex life.
The continents were barren, the skies faintly pink, and the oceans teemed only with microscopic life. This slow, soothing documentary guides you through the Mesoproterozoic Era — when oxygen was rising, continents were drifting, and the stage for future evolution was quietly set.

Soft narration and gentle pacing make this the perfect film for sleep, study, or calm reflection.

This video is created for educational purposes to explore scientific ideas in a peaceful, sleep-friendly format.
