Question:
What current theories are there about the Earth's abundant water origin?

Khoury,

Did you know that water vapour is a common product of volcanoes? Soon after Earth first fomed, the Iron Catastrophe occurred. This was followed by a period commonly referred to as a degassing of the planet. Sounds a bit funny, but what it means, is that when Earth was cooling down a lot of water vapors were released. This, coupled with the fact that Earth is the "Goldilock's distance" from the sun, allowed H20 to remain in a liquid state.
