Ron offered this in a comment. I think it's something visitors here should read

Rendezvous with RAMA?

Copyright 2022, InterAmerica, Inc.

While writing my post (below this one) I was being nudged by a review of Arthur Clarke’s sci-fi work, Rendezvous with Rama, that I recently saw by a fellow I follow on YouTube.

I won’t divulge much about the book – in case some visiting here haven’t read it yet (and it’s about to be made into a movie perhaps).
 
The point I’m about to make involves that academic trouble-maker Avi Loeb who thinks that the oumuamua object that flew into our solar system from interstellar space was, maybe, a probe from an advanced civilization somewhere in the cosmos.

 
(I accept and like Loeb’s conjecture. He also posits that a thing that landed in the Pacific Ocean in 2014 may have also been an object from outer space.)
 
Why a so-called advanced species would send a probe around the Universe, one that looks like a god-turd, goes to Clarke’s book.

Extraterrestrial civilizations with a 10,000 year existence?

One of the suggestions for those super-technological UFOs spotted by the Navy pilots a few years ago (and still) is that the things may represent aircraft from an advanced alien [ET] species that has a multi-eon advantage on us (humanity); that is, the flying artifacts represent aircraft derived by extraterrestrials who are visiting here from cosmic civilizations many years in existence.
 
Some suggest a 100 or 200 year leg up on Earth’s civi- lizations, which is okay with me, and a possibility.
 
But then some go further, speculating that ETs may be coming here from civilizations thousands of years ahead of us, even, perhaps, a million years in existence.
 
(A recent video I saw offered the so-called Silurian Hypothesis –   https://en.wikipedia.org/wiki/Silurian_hypothesis -- an idea that I find amenable for a possible past existence of societal creations here on Earth and maybe Mars, even Venus).
 
However, a million year or even a 10,000 year old civilization on a planet elsewhere in the cosmos derides the entropic experience – https://en.wikipedia.org/wiki/Entropy -- of all things.
 
No civilization on Earth, no societal enterprise existed beyond a few thousand years – https://www.ancienthistorylists.com/ancient-civilizations/10-oldest-ancient-civilizations-ever-existed/.
 
Even a speculated civilization – no matter how advanced it had become – can escape the process (societal and otherwise) of entropy.
 
Living and dead things are all subject to entropy, even a so-called advanced civilization reputed to be flying UFOs overhead and in our seas for millennia. The idea is preposterous and neurotically induced by persons with problems relevant to psychiatry.
 
Yet, the idea persists.
