AaS! 005: Where did the oceans come from?

Where did the oceans come from? Yeah, the answer is space, but are there any more details? Where does water come from anyway? Did the oceans come along with the earth or did they come later? Do we know anything about this at all? I discuss these questions and more in today's Ask a Spaceman! Keep those questions about space, science, astronomy, astrophysics, and cosmology coming to #AskASpaceman, Twitter@PaulMattSutter, }http://www.Facebook.com/PaulMattSutter, and }http://www.askaspaceman.com for COMPLETE KNOWLEDGE OF TIME AND SPACE!
