Long before the dinosaurs, Earth belonged to the eight-legged kings. Four hundred million years ago, during the Silurian and Carboniferous periods, the first true predators left the oceans and crawled onto land. These were the ancient arachnids — giant scorpions, early spiders, and their kin — creatures that ruled the primeval continents before trees had fully risen and before vertebrates had learned to walk on dry ground. In this calm, cinematic documentary, we explore how these pioneers conquered a world of swamps and storms, breathing air for the first time and shaping the earliest terrestrial ecosystems. Discover how gigantism evolved in a high-oxygen atmosphere, how ancient forests gave rise to vast coal swamps, and how the reign of arachnids set the stage for all land-based life to come. Through fossil evidence and deep-time imagination, we’ll journey into a forgotten age when giant scorpions hunted along misty shores and spiders wove the first silk traps beneath alien skies. Relax, listen, and step back into the dawn of life on land — a time before the dinosaurs, when arachnids ruled the Earth. #AllAboutEarth #documentaryforsleep #earthhistory
