is it possible we have looked at an alien civ but didn't see it because we are looking at their past?

I don't think they can see anything either way.  Not that detailed.  They discover some planets because of slight warbles or something like that that reveals a gravitational pull so they know there's a planet.  Then they can figure out how big the planet is which is just mind boggling to me.  I haven't looked it up, but I don't know that we "see" any planets outside our solar system or if we do, not many.
