The birth of our planet occurred approximately 4.54 billion years ago, when dust and gas left over from the formation of the Sun coalesced into a solid body. This early Earth was a violent place, constantly bombarded by asteroids and comets. The immense heat from these impacts, along with radioactive decay, kept the surface molten for millions of years. Over time, heavier elements like iron and nickel sank to form Earth’s core, while lighter materials rose to form the crust. This differentiation set the foundation for plate tectonics and the eventual development of life.
As the planet cooled, volcanic eruptions released vast amounts of gases, creating Earth's first atmosphere, primarily composed of carbon dioxide, water vapor, and nitrogen. Around this time, water vapor condensed into liquid form, leading to the formation of Earth’s first oceans. These ancient oceans would become the cradle of life, fostering the chemical reactions that led to the emergence of the first living organisms. The early stages of Earth’s formation were chaotic, but they set the stage for everything that followed.
