Probably the BLC-1 signal is from Proxima Centauri, probably not.

Some people believe that the BLC-1 (Breakthrough Listen Candidate 1) signal is not coming from Proxima Centauri(1). And the reason for that is that its origin uses synthetic radiofrequency. The thing is that can tell something about the signal itself. And that means the signal was not mean for us. So it is not probably an attempt to make contact with the human race. And that means that the BLC-1 radio signal is interesting anyway.

In some wildest visions, it's the alien civilization's internal communication. But we know that there is probably no civilizations on the planet of Proxima Centauri. So one of the most interesting possibilities is that the signal is coming from some interstellar probe. But that kind of thing is only speculations.

Extraterrestrial signals might not mean the attempt to make contact with us or any other civilizations.

Even if BLC-1 is coming from Proxima Centauri. The use of synthetic frequency might mean that it's for the internal messaging of the senders. So the extraterrestrial message is not mean that it's an attempt to contact us.

It might mean for control- or aiming signal for interstellar probes. In some visions, extraterrestrial civilizations can send two types of signals what are using different frequencies.

1) Use of the Hydrogen emission frequency use to attempt to make contact with other civilizations.

2) Synthetic radio frequencies are for civilization's internal messages.

Use of those synthetic frequencies could be reserved for sending orders for space probes and another message together. The synthetic frequency protects the data from disturbing and that's why we are using synthetic frequencies for communication.

The idea when people are talking about the signal what comes from the direction of Proxima Centauri or some other star is that we are talking about a thing, what might come from another star. The thing is that if the signal is using synthetic radiofrequency makes that signal interesting. The use of synthetic frequency means the high possibility that a sender is an artificial machine. And another thing is interesting.

About the possibility of that BLC-1 signal send by the interstellar probe.

Could the sender of the message the interstellar probe? There is a tale that the thing that was capture in the Roswell incident was an unmanned probe. But there are so many tales about that case that nobody knows what is true and what is fake.

When we are thinking about the possibility that an interstellar probe that thing causes fascinating thoughts. Humans are making the models of the interstellar spacecraft(2). And even if they would be robot spacecraft that are using artificial intelligence to control their operations. Those futuristic spacecraft are the enormous systems that mankind ever imagined. Even unmanned versions of the interstellar spacecraft models would have a length of kilometers, but before we make them we need some promising star where to send those spacecraft.

So in some models, the interstellar probes have sub-probes, which they can send to solar systems when they are traveling near them. That means that there is a possibility that an interstellar probe can be in our solar system. So what kind of possibilities that kind of probe could give us, if we are finding this kind of spacecraft on our planet.

So when we are searching the extraterrestrial civilizations we might not find them very close. There is one sun-type star in 1800 light-years away from Earth(3). That means that this civilization if it exists might not visit here very soon. Sending the message to that star takes 1800 years, and their answer will take 1800 years. So that means that the communication between that civilization and us would take 3600 years. And that is a very long time.
