That is interesting, and it changes my math a bit, though not to your favor;

>Based on the survey, scientists predict that there should be 1 billion Earth-sized worlds in the Milky Way galaxy at present, a good portion of them presumed to be rocky. That estimate skyrockets when you include the other 100 billion galaxies in the observable universe.

So for us to be near the first, near enough not to trip on Fermi's paradox, and allowing a short 5 billions years for these planets to have existed on average; we are (1000 billion X 5 billion) to 1. Which still needs one hell of a filter to explain.
