4 Billion Years of Prehistoric Earth Before Dinosaurs | Documentary for Sleep

Everything you know about prehistoric life begins too late. The dinosaurs appeared 230 million years ago. The Earth is 4.5 billion years old. That means between the formation of our planet and the first dinosaur, there is a span of time eighteen times longer than the entire age of the dinosaurs. Tonight we explore those four billion years — the deepest history of Earth that almost never gets told. We begin in the Hadean — when the Earth was a magma ocean and the Moon had just been born from the impact of a Mars-sized world. We descend into the Archean — where the first life appeared in the warm iron-green ocean beneath an orange sky. We watch the Great Oxidation Event transform the atmosphere and freeze the planet. We witness the Ediacaran — the first animals, soft-bodied and peaceful, living in an ocean without predators. We stand in the Cambrian ocean when eyes first appeared and changed the rules of life forever. We walk through the first forests of the Devonian. We breathe the oxygen-rich air of the Carboniferous coal swamps where dragonflies had 70-centimeter wingspans. We watch the extraordinary Permian ocean — the most diverse marine ecosystem in Earth's history — and then we watch it end. Four billion years. Before the dinosaurs were even imagined. Dim the lights. Take a slow breath. Let the deep past carry you. 🎵 Deep ambient music throughout 🌍 Hadean, Archean, Proterozoic, Ediacaran, Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian #DocumentaryForSleep #SleepDocumentary #PrehistoricEarth #BeforeDinosaurs #Paleontology #CambrianExplosion #SnowballEarth #GreatOxidationEvent #Ediacaran
