What are some things that happened on earth?

Answer 1

Throughout Earth's history, significant events include the formation of the planet approximately 4.5 billion years ago, the emergence of life around 3.5 billion years ago, and the development of complex organisms leading to the Cambrian explosion about 540 million years ago. Major extinction events, such as the one that wiped out the dinosaurs 66 million years ago, shaped the evolution of life. Additionally, the rise of human civilization over the past few thousand years has led to profound changes in the planet's environment and ecosystems.
