Earth 3.5 billion years ago, was nothing like what it is today. No plants, animals, nothing. Volcanoes erupted poisonous gases, methane and ammonia was in the atmosphere, and it would have been impossible to breathe. The Earth was also only one continent (until it was later broken up into several, which is another topic). Acidic rain, and deadly thunderstorms occurred for several millions of years. This is a shot in the dark, but it most likely (as we have no actual idea of what it *looked* like) resembled Mars. Lifeless, and unlivable. By the way, I find it odd that if the earth is 4 billion years old, and Mars is just as old, why there is no life on Mars (at least nothing like Earth's life), but there is life on the Earth. Kind of an interesting question huh?

What are the 4 eras of early earths history?

The four eras of early Earth's history are the Hadean, Archean, Proterozoic, and Phanerozoic. The Hadean (about 4.6 to 4 billion years ago) is characterized by the formation of the Earth and its initial cooling. The Archean (4 to 2.5 billion years ago) saw the formation of the first stable crust and the emergence of simple life forms. The Proterozoic (2.5 billion to 541 million years ago) featured significant geological and biological developments, including the rise of multicellular life, while the Phanerozoic (541 million years ago to present) is marked by the abundant fossil record and the diversification of life forms.
