How much water really is there on Spaceship Earth?

We're told that all the water on Earth came here via comet impacts. That's a fact that's pretty hard to reconcile. I mean there's just so much water right?

Not when you look at it all balled up and sitting next to the planet...

And not when you compare it against all the liquid water in Saturn's moon Titan - not even compared to the water on Jupiter's moon Europa.

The heavy bombardment period must have been a pretty serious time to be around...
