Earth's H2O Most Likely Came From Asteroids

Tim Sayell sends in an article from Yahoo News that pretty much confirms something that we suspected - that Earth's water came from water bearing asteroids.

From the article:
  • Astronomers have for the first time detected ice and organic compounds on an asteroid
This goes a long way towards supporting that ice comets and asteroids crashing to Earth during early planetary formation some 4 billion years ago, seeded the planet with water and carbon-based molecules. Though it has long been theorized, this is the first time that scientists have published hard data supporting the theories.

It may be that asteroids were responsible for 20 to 30% of the total amount of terrestrial water.
