But you would still need to be right on top of the planet to see the debris. The best we can do with regard to even SPOTTING planets our size in our solar systems is to detect faint fluctuations in light and color shifts from red to blue. While we have vastly improved our ability to measure those shifts, we have still looked at only ~1900 exoplanets in ~1200 planetary systems. Now how many starts are there?
Some estimates peg that number at roughly 100 octillion stars. So the number we have even remotely been able to assess allows us ZERO room to make extrapolations about what the rest may contain. That would be the equivalent of guessing who will win the Presidency next year based on which name in a phone book a hamster walked over.
