How was the ocean made?

The ocean was made by comets. When comets hit the earth, it added more and more water to the surface. When the Solar System was being made, not a single trace of water was found on Earth. There were comets all over the Solar System. So of course, comets would end up hitting the earth.

A comet has ice in it. When a comet gets closer to the atmosphere, it heats up and the ice turns into water. Whenever the comet strikes the earth, it bursts and water is added.
