Question: How was Earth created?

Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

Where did the earth come from?

Earth formed from debris orbiting around our sun about 4 ½ billion years ago. That is also the approximate age of the sun, but it is not the beginning of our story. The story really begins with the Big Bang nearly 14 billion years ago, which spewed hydrogen atoms throughout the universe.

How did Earth look in the beginning?

The Earth formed more than 4 billion years ago along with the other planets in our solar system. The early Earth had no ozone layer and was probably very hot. The early Earth had no oceans and was frequently hit with meteorites and asteroids. There were also frequent volcanic eruptions.

Will humans become extinct?
