Early Earth
Early Earth, a fascinating chapter in our planet's history, unfolds a narrative of dynamic geological processes and the emergence of life. Spanning from its formation approximately 4.6 billion years ago to the end of the Proterozoic eon around 541 million years ago, Early Earth sets the stage for the intricate interplay of geological events that shaped the planet's surface and atmosphere. Delving into this epoch opens a window to the origins of Earth's landscapes, the evolution of its early atmosphere, and the gradual development of the conditions necessary for the inception of life.
