Intelligent alien civilizations may be broadcasting all around us, but human technology isn't advanced enough to detect it yet, because these aliens have probably advanced beyond electromagnetic radio communications. The chances of another civilization using the same technology as us at the same time in a nearby location in the galaxy is very remote. In the case of the alleged Proxima Centauri signal, it's looking more and more like it's either a satellite in geosynchronous orbit, or the Parkes radio dish may have inadvertently picked up a signal from the super-secret CIA/NSA Pine Gap intelligence station, also located in Australia. Very low probability this is ET calling.
