It has been taken for granted that the inner portion of the early Solar System was too dry to allow water to remain on the newly-formed rocky planets.
Also, it has been taken for granted that when new stars begin their main sequence burn, it moves all of the lighter materials away from the central area of the new system, clearing the inner area completely of dust, vapor and that sort of thing.
However, some interesting studies are coming in that tell a different story. One, I believe, will soon allow us to see that water formation on inner planets throughout the universe is far more common place than ever thought possible:
1) Solar wind, carrying Hydrogen can combine with other sources of Oxygen while in space to make water molecules:

2) Water in space can serve a function in the early development of a 'Solar System':

3) Oxygen is a gas often found around nebula (second phase stars):

4) Inner planets do have evidence of water.

Combine all that with the notion that when our star went 'Main Sequence' early on, it may not have totally remove all gas and dust from the central area (otherwise the inner planets wouldn't have had the chance to form from such dust), and it is starting to look very exciting that "Earth-like" planets, complete with water oceans, could have more easily formed elsewhere in the universe. -- Not really requiring Comets and Asteroids to hail in later to produce a chancy ocean-forming situation. Oceans could be easily formed from the get go, it's starting to look like to me.
