How Earth was Born

Those first oceans may have been short-lived. Chunks of rubble in space may have became the greatest impacts, forcing the process of cooling and condensation again.
Earth was born 4.6 billion years ago. Rocks and Ice particles swirling around the young sun. Then, it collided to begin making a size of a planet.
It was only filled with hot volcanoes. As it grew bigger, gravity was now formed. Asteroids hit earth making it bigger and bigger. But a planet of a size of Mars struck the planet so hard that it moved into orbit.
After moon's fiery birth, Earth's surface cooled down. But even after that, it remained as an alien world for 700 million years.
By 3.8 billion years ago the impacts relented. Water could now persist. Perhaps in the ocean the molecules could now reproduce and evolve. Little by little the atmosphere was turned into breathable air.
Those days are long gone. But the history of how earth was born is still on view today.
