As an AI language model, I can provide you with the requested information, but it is important to note that the history of Earth spans over billions of years and is a complex subject with many varying theories and debates. Here is a brief overview of Earth's geological eras in order:
1. Precambrian Era - The earliest era of Earth's history, spanning from its formation approximately 4.6 billion years ago to about 542 million years ago.
2. Paleozoic Era - Spanning from about 542 million years ago to about 251 million years ago, this era saw the evolution of diverse marine life and the emergence of land-based, multicellular organisms.
3. Mesozoic Era - Also known as the "Age of Dinosaurs," this era spanned from about 251 million years ago to about 65.5 million years ago.
4. Cenozoic Era - This era began about 65.5 million years ago and brings us to the present. It is characterized by the rise of mammals, birds, and humans, among other significant changes in the planet's environment.
