Understanding Earth's Vast History in a Manageable Timeline
Earth's history spans approximately 4.6 billion years, encompassing the formation of the planet, the emergence of life, and significant evolutionary milestones. To better grasp the immense timescales involved, we've condensed this vast history into a 46-year timeline. Each year in this scaled timeline represents roughly 100 million years, allowing us to visualize and appreciate the major events that have shaped our world.
Below is a table listing various historical and prehistorical events, scaled to fit within this 46-year framework. This visualization highlights the relative brevity of human existence compared to the planet's extensive history.
