Earth's Water

Scientist have speculated as to how the Earth got it's oceans. The most popular theory is that Earth got bombarded with icy asteroids and that ice become our oceans. But have you looked out into the ocean and said "that's a lot of water" and wondered how many icy asteroids it would have taken to fill the oceans? If that's the case then why does Venus and Mars barely have any water? Those planets surely got bombarded with icy asteroids too right?
Scientist also say that icy bodies form in the outer regions of the solar system because the sun's heat vaporizes the ice. One of Jupiter's icy moon is said to have the same water composition as our oceans.
When Jupiter formed it started falling towards the sun until the outer gas giants gravity started pulling Jupiter out again. What if Earth was one of Jupiter's icy moons that was left behind in a tug of war with the Sun when Jupiter started heading out ward again? What if all that ice melted to give us the oceans we have today?
