    Originally, a lot came from the oxidation of hydrogen gas. On Earth, much of the water came from volcanic outgassing. There may be a significant component added by objects from the outer solar system (comets, etc).

    Probably, much of the water was originally locked up in hydrous minerals, released during metamorphism, and transported to the surface through magmatism.

    The origin of water on Earth, or the reason that there is clearly more water on the

    Earth than on the other planets of the Solar System, has not been clarified.
