If 3, And The are truly advanced we should consider not communicating with them. Maybe they are hiding from someone else... ;) https://en.wikipedia.org/wiki/Dark_forest_hypothesis
That leaves radio communication, but the latest intel they have on us left earth around 1900. At that point we wouldn't have been able to receive anything from them. It's probably questionable if we would have picked something up had they sent a radio signal our way a week ago. Right now SETI might have a radio antenna pointed their way, but that won't last indefinitely, and these events are a bit hard to time from 120 lightyears away.
