The Earth formed as a molten mass, with a temperature too high for liquid water to exist. Scientists now suspect that much of the Earth's water was provided by a large number of impacting icy meteors and comets after the cooling was completed. A large volume of water ice is still present in such objects within the solar system, as dramatically evidenced by the ice rings around the planet Saturn (equal to about 1% to 3% of the volume of Earth's oceans).

Water remainded a gas because Earth was too hot before the ocean was formed.
