The ocean was formed 4 Billion Years Ago. The ocean formed when the Earth cooled down. The ocean formed from two sources, out gassing from within the Earth and bombardment by comets. Out gassing is the process where gasses are released from molten rock in the mantle of the core of the planet by volcanic activity.

Earth was formed 4.6 Billion years Ago. It was a ball of ice, dust, and rock pulled together by granite. Earth formed after the sun was formed. There were leftover gasses and heavy elements that collided and formed plantsimals and planetoids. Over time these would collide forming planets. By this method Earth was eventually formed.
