The Hadean Period Was Pure Hell

The Hadean period refers to the first 500 million years of the planet’s history. During this time, the earth was so hot that it was mainly a giant ball of molten rock. Scientists named this period the Hadean after the ancient Greek god of the underworld, Hades.

We don’t know very much about the Hadean period because there are very few rocks that are more than 3.8 billion years old. The Hadean period came to an end about four billion years ago, so much of it is a mystery. Nevertheless, we know one thing for sure: it is not a state that we, as humans, would be able to survive.
