This is actually a difficult question. If the surface of the earth were completely flat, it would all be covered with water. If the oceans were a lot deeper than they are, far less of the surface would be covered with water. It's really two parts to the question: 1) why is there as much water as we have, and 2) why is the surface of the earth relatively flat (only a few miles difference between the height of the tallest mountain and the depths of the deepest part of the ocean--far less than 1% of the diameter of the earth)? The answer to the first question is one of chemistry, and I don't really know how to answer it. The answer to the second question is one of physics and geology; it has to do with the force of gravity pulling everything together into a ball shape and the forces of wind and water further tending to flatten things out.

The oceans' size depends on the movement of tectonic plates.

because, there was a flood, a long time age, it rained for forty days and night, and it coverd the whole earth, when it stopped raining, the water seperated the land mass and made lager bodies of water, oceans!! :)

Because there is a lot of water, and we need some place to keep it.
