To: null and void

Got me there. How about the next? point being though, out of trillions of stars, we or they have not had the time broadcasting to see each other.

I think that transmission is probably in a bubble so vast that by now it contains hundreds of stars*. OTHO, it's so faint by now as to be utterly undetectable.

Detectable signals probably have only reached a few scores of stars. Odds are we haven't gotten a recognizable transmission to any technological civilization.

Worse, the first signals anyone is apt to receive aren't coherent broadcasts, they aren't 'easily' decoded entertainment radio or TV, they are powerful early warning radar transmissions, and those consist of randomly (or as close to randomly as we could achieve) modulated signals, the better to prevent spoofing.

Even if someone happened to be looking here in the correct radio band, and at the correct time, they'd just get literally meaningless noise!

*Average distance between stars in our neck of the woods is something like 5 light years. In the roughly 100 years we've been broadcasting that bubble has about 400 stars.
