Although the Earth (and other planets in our solar system) was formed via the condensation of a dust and gas ridden cloud, this was not the direct cause of the formation of the ocean. Water vapor began escaping from Earth's interior. Over time this vapor condensed and cooled. Additional water was brought to Earth by comets. Information can be found in the section Stars and Seas.
