Imagine if a robotic probe arrived in our Solar System, sent by an ETC. They detected us and sent their probe to introduce themselves and learn more about us.
Then imagine our sensors detect another incoming probe from the same place as the previous one. Imagine our surprise when we retrieve it, and begin to study it, only to find that it's not as advanced as the previous one and contains older information and messages than the first one.
That's exactly what might happen, according to Graeme Smith. Smith is a professor and an astronomer at the Department of Astronomy and Astrophysics at the University of California.
Smith points out that sending probes on journeys of such extreme distances means the first one received wouldn't be the first one that was sent. As technology advances, we can expect probes to become faster. Eventually, a probe launched later than its predecessor would overtake its predecessor and reach the destination first.
The first probe [sent] might not even be interstellar, at least not on purpose. Our own Voyager probes can rightly be called interstellar probes, though that wasn't their intent. The same could be true for an ETC just embarking on a program of sending probes to other star systems.
"If an object sent by an interstellar ETC were to enter the Solar System, chances are it would not be a relic artifact that is perhaps analogous to a timeworn Voyager-like probe, but rather one might expect a vehicle of much greater sophistication, even if it were no longer functioning," Smith writes.
"As Hawking (2010) and others have drawn attention to, some potential consequences of such a first-contact event might be of serious concern for humanity."

Chords fifths tones. Music is math, math is music.
Whatever do you mean by that?
There are proponents of us being holograms. I don't believe in that theory but that theory is even gaining traction with respected physicists.
If we, by chance, are a hologram then nothing in our perception is physically real, only virtually real. That would include encounters with other civilizations.
I guarantee you ... they know about hydrogen, and helium, and lithium and all the rest
As for the elements being universal, yes to the extent we know them and their light emissions from other celestial measurements.
That doesn't guarantee that other life forms would perceive them as we do. What if their world is made of antimatter? What if they have no interest in atomic theory as we use it?
“If we, by chance, are a hologram then nothing in our perception is physically real, only virtually real.”
The hologram theory is a simplification of what is being proposed—because we don’t have very good language to describe it.
One of the best analogies I have read is this:
Imagine that what we call “reality” is a computer screen with icons on it.
We can accomplish all the tasks we need by clicking on the appropriate icons and using whatever software is there.
However, no matter what wonderful “things” we can accomplish with that method we are not discovering “the nature of the universe” because we have no access to the actual 0s and 1s that make up the software—we do not even know they exist.
There could be alien civilizations that “discovered” the 0s and 1s and learned how to “hack” the software so the screen could be made to do “impossible” things.
Our “laws of physics” would just be the “laws” governing the computer screen and the icons, and would have nothing to do with the underlying structure supporting them.
Music is perceived by those who have ears and a need to find meanings in the sound.
I recommend “The Three Body Problem” by Cixin Liu. It’s a tough, three-volume massive work that is well worth the effort. It’s based on the “Dark Forest” theory that inhabited space is a wildly dangerous place and survival depends upon being very, very quiet since discovery invariably meant death for the planet. Superior technology always saw other intelligences as a threat.
3D glasses make this work pretty well, it shows the nearest stars.
(List of nearest stars and brown dwarfs page)
this list shows Alpha Centauri, although the red dwarf Proxima Centauri is the closest of the three stars (Rigil Kentaurus (Alpha Centauri A), Toliman (B) and Proxima Centauri (C)):

Then they're not getting here, and we're not getting there. They're not just far away, they're in a completely different and incompatible reality from us.
What if they have no interest in atomic theory as we use it?
Then they fall into the category of slightly smarter than a dog. Seriously ... it's not a matter of "atomic theory as we use it". It's a matter of atomic theory full stop. There are universals. Atomic structure is one of them.
If we, by chance, are a hologram then nothing in our perception is physically real, only virtually real.
Now you're getting into some weird realms of philosophy and theology (yes, I read your PM) ... But almost every theistic religion, including my Christianity, basically holds that we exist because God said so, and the universe is the way it is because God wants it that way. As scientists, we're working out exactly what God said ... as engineers we're finding ways to manipulate what God said to our purposes. And any "aliens" we might meet which come from our physical reality are working with the same things God said that we are ...
And then there's the belief that "aliens" are really beings from a non-physical part of what God said; that they're really demons posing as flying-saucer pilots ... And if that's the case, I actually agree that we have no hope of really understanding them and that they're not bound by the laws of physical reality.
On the subject of universals, pure mathematics is another, as is basic physics. Pi only equals 3.14159265etc in base-10. But pi equals the circumference of a circle divided its radius. The gravitational, electrical, and magnetic forces are all inverse radius squared phenomena. Everywhere. There are others ... break these, and the universe just doesn't work any more.
Nobody told them about reruns.

Music is perceived by those who can sense vibrations ... and understand that vibrations mean things.
No need to ‘hear’ vibrations carried through a gas, liquid or plasma medium. Vibrations can be sensed directly; its so easy even a human can do it.
On our planet, the concept of zero wasn’t even used until the 1200s AD.

Our current 12,800 year old civilization ... Planet is a different matter, with a history going back almost 5 billion years. How many civilization can rise, fall, vanish, and the very ground they stood on be subducted in that time frame, even civilizations that lasted mullions of years? No one says that ‘people’ have to look like us or even be of the same species.
That proves the obviously inferior intellect.
Because they would all have “Made in Pleiades” on them. Duh..

The writer, Andy Weir, just wrote a book that describes meeting a different race in deep space. It goes through the process of learning how to communicate. It starts with common items…like the atomic models of hydrogen and oxygen.
In essence…if the two parties are dedicated, they can figure it out pretty quickly.
