Universe & Earth Formation Timeline

This document provides a summary of events from the creation of the universe to around 5509 BC. It describes the formation of the Milky Way galaxy and solar system, with events such as the Earth's creation 4.5 billion years ago from the collision of two proto-planets. Early life first evolved around 4 billion years ago in the oceans, initially as simple bacteria and later more complex single-celled organisms. Oxygen levels in the atmosphere gradually increased over time. The earliest continents formed and broke apart over hundreds of millions of years during this period before the dawn of history.
