Currently, virtually all SETI (search for extraterrestrial intelligence) experiments scan the skies looking for radio or light signals. However, over the years, some researchers have suggested that another, potentially better way to find evidence of alien life is to not look for broadcasts from afar, but instead to hunt for what are essentially messages in a bottle — a SETA (search for extraterrestrial artifacts) approach.
For example, in 2004, researchers suggested that broadcasting a signal across the cosmos is expensive and inefficient. Instead, the scientists calculated that inscribing messages onto a hunk of matter and launching it at potential extraterrestrial pen pals would require about a trillionth as much energy.
Another concern with conventional SETI is that extraterrestrial civilizations may be long dead by the time astronomers do actually detect signals from them. In contrast, extraterrestrial artifacts could provide a way for us to directly learn about alien civilizations, especially if these artifacts are equipped with artificial intelligence...
In the new study, Benford developed a version of the Drake equation for artifacts. The new formula specifically focused on what he calls "lurkers" — hidden and likely robotic extraterrestrial probes. Although the civilizations that deployed these lurkers may well be dead, the lurkers themselves could still be active enough to communicate with us.

Why would they — highly advanced space-faring ETs — use anything as obsolete and quaint as “radio.” Even we are using “spread-spectrum” stuff, which in a narrow channel, sounds and looks like random noise.
I wager ole MR. ET has something much better...
Funny how no one has come up with so much as a dropped tool, or a nut and bolt or an empty beer can of demonstrably alien origin.
Duck Duck Go is a search engine. Google gives better search results, but I try to avoid it. Sometimes I have no choice when DDG delivers poor results.
In this case you asked “why”, the straight answer is I just wanted to post quickly. So I searched, saw the artifact, right clicked to copy image link, and then pasted it into the reply.
Here is the source article where the image came from.

As to why anyone would make a rendition of a rendition I can only guess that they wanted to avoid copyright issues. But it’s not like Kubrick is the only person entitled to put Clarke’s ideas into graphical art.
I joke about this with my wife and her best friend. They are Ancient Aliens fans. I say “so you are telling me that intelligent life in another galaxy had the means to travel light years to get to earth, only to build pyramids made of heavy stones?”
They tell me “no, the pyramids are a source of energy, or helps them navigate, or send communications around the globe” and again I say “they can travel across the stars presumably at or near light speed, but they need heavy stones pyramids as their GPS?”.
Then of course, there’s they “aliens need our gold”.
Because of course we 21st-century human beings would easily recognize technological artifacts of a million-year-old civilization for what they are.
Seriously: What would Leonardo da Vinci have made of a solid-state circuitry? A flat-screen? How about a 24-inch cathode ray tube? What would he have made of them, even if they were still in pristine condition? Since he doesn't have a working electrical socket into which to plug them... And doesn't actually even understand the concept of "plus" pole and "negative" pole... And that's a technological gap of a mere 500 years. Now imagine: 500,000 years.
Clarke's 3rd Law:
Any sufficiently advanced technology is indistinguishable from magic.

Something tells me they are closer than the moon.
“Alien hunters should search for artifacts on the moon, study suggests”
This is an excellent and instructive use of the word “study”.
This is precisely how the word “study” is used by the media these days.
The so-called study is pure speculation. Nothing was “studied”. This guy just speculates that maybe aliens have sent probes that crashed into the moon, and therefore we should be looking for them on the moon.
Alien gum wrappers, cans, etc...
“scientists calculated that inscribing messages onto a hunk of matter and launching it at potential extraterrestrial pen pals would require about a trillionth as much energy”
It would probably also be a trillionth less likely to ever be noticed. A radio wave propagates in all directions, unlike a chunk of rock which can only fly to one place and then wait for someone to find it.
Silly argument though, since there are no aliens either way.
SO SPRACH ZARATHUSTRA
... and they’re always crashing somewhere...
Alice Kramden!! To the moon, Alice!!!
LOL!!!
The moon is loaded with artifacts made by Someone.
If you have sufficient resources and technical know how, you can get a reasonably powerful reflector telescope, a decent SLR and attachments for the ‘scope, hook to a PC running imaging software and be able to take as good an image as many professional observatories.
They have been repeatedly photographed, but continually dismissed as fakes, light and shadow, etc. In other words, nothing to see, move along.
YET ...
“The Moon is the Rosetta stone of the planets.” Robert Jastrow, First Chairman, NASA Lunar Exploration Committee
After hundreds of years of detailed observation and study, our closest companion in the vast universe, Earths Moon, remains an enigma. Six Moon landings and hundreds of experiments have resulted in more questions being asked than answered.
1. Moons Age
The Moon is far older than previously expected. Maybe even older than the Earth or the Sun. The oldest age for the Earth is estimated to be 4.6 billion years old; Moon rocks were dated at 5.3 billion years old, and the dust upon which they were resting was at least another billion years older.
2. Rocks Origin
The chemical composition of the dust upon which the rocks sat differed remarkably from the rocks themselves, contrary to accepted theories that the dust resulted from weathering and breakup of the rocks themselves. The rocks had to have come from somewhere else.
3. Heavier Elements on Surface
Normal planetary composition results in heavier elements in the core and lighter materials at the surface; not so with the Moon.
According to Wilson, “The abundance of refractory elements like titanium in the surface areas is so pronounced that several geologists proposed the refractory compounds were brought to the Moons surface in great quantity in some unknown way. They don’t know how, but that it was done cannot be questioned.”
4. Water Vapor
On March 7, 1971, lunar instruments placed by the astronauts recorded a vapor cloud of water passing across the surface of the Moon. The cloud lasted 14 hours and covered an area of about 100 square miles.
5. Magnetic Rocks
Moon rocks were magnetized. This is odd because there is no magnetic field on the Moon itself. This could not have originated from a “close call” with Earth as such an encounter would have ripped the Moon apart.
6. No Volcanoes
Some of the Moons craters originated internally, yet there is no indication that the Moon was ever hot enough to produce volcanic eruptions.
7. Moon Mascons
Mascons, which are large, dense, circular masses lying twenty to forty miles beneath the centers of the Moons maria, “are broad, disk-shaped objects that could be possibly some kind of artificial construction. For huge circular disks are not likely to be beneath each huge maria, centered like bulls eyes in the middle of each, by coincidence or accident.”
8. Seismic Activity
Hundreds of “Moonquakes” are recorded each year that cannot be attributed to meteor strikes. In November, 1958, Soviet astronomer Nikolay A. Kozyrev of the Crimean Astrophysical Observatory photographed a gaseous eruption of the Moon near the crater Alphonsus. He also detected a reddish glow that lasted for about an hour.
In 1963, astronomers at the Lowell Observatory also saw reddish glows on the crests of ridges in the Aristarchus region. These observations have proved to be precisely identical and periodical, repeating themselves as the Moon moves closer to the Earth. These are probably not natural phenomena.
9. Hollow Moon
The Moons mean density is 3.34 gm/cm3 (3.34 times an equal volume of water) whereas the Earths is 5.5. What does this mean? In 1962, NASA scientist Dr. Gordon MacDonald stated, “If the astronomical data are reduced, it is found that the data require that the interior of the Moon is more like a hollow than a homogeneous sphere.”
Nobel chemist Dr. Harold Urey suggested the Moons reduced density is because of large areas inside the Moon where is “simply a cavity.”
MITs Dr. Sean C. Solomon wrote, “the Lunar Orbiter experiments vastly improved our knowledge of the Moons gravitational field ... indicating the frightening possibility that the Moon might be hollow.”
In Carl Sagan’s treatise, Intelligent Life in the Universe, the famous astronomer stated, “A natural satellite cannot be a hollow object.”
10. Moon Echoes
On November 20, 1969, the Apollo 12 crew jettisoned the lunar module ascent stage causing it to crash onto the Moon. The LMs impact (about 40 miles from the Apollo 12 landing site) created an artificial Moonquake with startling characteristics the Moon reverberated like a bell for more than an hour.
This phenomenon was repeated with Apollo 13 (intentionally commanding the third stage to impact the Moon), with even more startling results. Seismic instruments recorded that the reverberations lasted for three hours and twenty minutes and traveled to a depth of twenty-five miles, leading to the conclusion that the Moon has an unusually light or even no core.
11. Unusual Metals
The Moons crust is much harder than presumed. Remember the extreme difficulty the astronauts encountered when they tried to drill into the maria? Surprise! The maria is composed primarily illeminite, a mineral containing large amounts of titanium, the same metal used to fabricate the hulls of deep-diving submarines and the skin of the SR-71 “Blackbird”. Uranium 236 and neptunium 237 (elements not found in nature on Earth) were discovered in lunar rocks, as were rustproof iron particles.
12. Moons Origin
Before the astronauts Moon rocks conclusively disproved the theory, the Moon was believed to have originated when a chunk of Earth broke off eons ago (who knows from where?). Another theory was that the Moon was created from leftover “space dust” remaining after the Earth was created. Analysis of the composition of Moon rocks disproved this theory also. Another popular theory is that the Moon was somehow “captured” by the Earths gravitational attraction.
But no evidence exists to support this theory. Isaac Asimov, stated, “Its too big to have been captured by the Earth. The chances of such a capture having been effected and the Moon then having taken up nearly circular orbit around our Earth are too small to make such an eventuality credible.”
13. Weird Orbit
Our Moon is the only Moon in the solar system that has a stationary, near-perfect circular orbit. Stranger still, the Moons center of mass is about 6000 feet closer to the Earth than its geometric center (which should cause wobbling), but the Moons bulge is on the far side of the Moon, away from the Earth. “Something” had to put the Moon in orbit with its precise altitude, course, and speed.
14. Moon Diameter
How does one explain the “coincidence” that the Moon is just the right distance, coupled with just the right diameter, to completely cover the sun during an eclipse? Again, Isaac Asimov responds, “There is no astronomical reason why the Moon and the sun should fit so well. It is the sheerest of coincidences, and only the Earth among all the planets is blessed in this fashion.”
15. Ages of Flashes
Aristarchus, Plato, Eratosthenes, Biela, Rabbi Levi, and Posidonius all reported anomalous lights on the Moon. NASA, one year before the first lunar landing, reported 570+ lights and flashes were observed on the Moon from 1540 to 1967.
16. Operation Moon Blink
NASAs Operation Moon Blink detected 28 lunar events in a relatively short period of time.
17. Lunar Bridge
On July 29, 1953, John J. ONeill observed a 12-mile-long bridge straddling the crater Mare Crisium. In August, British astronomer Dr. H.P. Wilkens verified its presence, “It looks artificial. Its almost incredible that such a thing could have been formed in the first instance, or if it was formed, could have lasted during the ages in which the Moon has been in existence.
18. The Shard
The Shard, an obelisk-shaped object that towers 1 miles from the Ukert area of the Moons surface, was discovered by Orbiter 3 in 1968. Dr. Bruce Cornet, who studied the amazing photographs, stated, “No known natural process can explain such a structure.”
19. The Tower
One of the most curious features ever photographed on the Lunar surface (Lunar Orbiter photograph III-84M) is an amazing spire that rises more than 5 miles from the Sinus Medii region of the lunar surface.
20. The Obelisks
Lunar Orbiter II took several photographs in November 1966 that showed several obelisks, one of which was more than 150 feet tall. “... the spires were arranged in precisely the same was as the apices of the three great pyramids.”
Let’s assume space folds over on itself - that they’re really not that far away... then come up with a way to communicate based on that reality.
Any artifact found on the Moon was put there after 1959. Just sayin.
I’m with you on this. I was being facetious. A truly advanced civilization may not find us worth talking to. They may not even be organized into what we regard as a civilization.
