The Story of Earth - History of the Universe - One Minute History

Planet Earth formed from stellar dust and rocky debris under gravity, initially as a molten mass with a toxic atmosphere. A collision with Theia created the moon. Asteroids cleared the way for microbial life, leading to the formation of oceans and oxygen. Supercontinents formed and split, causing ice ages and greenhouse periods. Life evolved from algae to multicellular organisms, with significant events like the Cambrian explosion. Extinctions and evolution led to the rise of land plants, mammals, dinosaurs, and Hominins. Earth's history is divided into four aeons, 10 eras, 12 periods, and seven epochs.
