There have probably been trillions of alien civilizations, and yet we may still never see one

Why would advanced civilizations use primitive communications? If they’re advanced enough to travel FTL they’re probably advanced enough to communicate FTL.

For example:

There’s plenty of current discussion of wormhole-type propulsion systems to traverse vast distances at FTL-relative speeds. Why wouldn’t similar technology be used for FTL radio via a wormhole repeater? The wormhole would only need to be large enough to get a radio signal through to a repeater on the other side. Therefore much greater distances could be spanned by the wormhole for the energy used since the wormhole only needs to be large enough to carry a radio signal. The radio signals would only need to be strong enough to reach their audiences at the wormhole repeaters’ source and destinations.

We already know the impracticality of using standard radio waves for inter-stellar communication so why would more advanced civilizations use it? If they did use radio waves they would, by necessity, incorporate advanced technologies to make it practical. Advanced communications would thereby not conform to the current, impractical use of standard radio waves -which SETI is pointlessly searching for.

Years ago Carl Sagan told us that when SETI opened they would aim their radio telescopes at difference sectors of the sky and we would hear the cacophony of the universe - voices of millions of other civilizations...

It didn't happen.

Years went by and slowly excuses started trickling out... then those stopped as the realization sunk in that we might be alone...

I’m familiar with SETI.....I have a family member that was all about UFO’S and all that goes with those who follow it. We went toe to toe many times.....

Of course there are Unidentified Flying Objects that people can’t rightly identify....and the UFO folks are always on them like hot potatoes only to discover later it’s been identified.

After several years ‘spent’ chasing UFO stuff our family member finally wrapped it up when the light dawned he was feeding a business where a lot of people make a lot of money pushing this stuff...and ‘Nothing’ proves what they try so hard to prove and fail to do.

Rubbish. This is like saying there are thousands of exact original Mona Lisa paintings in the universe. It is much more likely that we are the only intelligent life to have ever developed in the cosmos. The chain of fortunate events leading to our existence is far too long to have been replicated elsewhere.

10 SETI Messages That We May Not Want to Receive An exploration of alternative SETI messages that may not say hello. | Published on Nov 6, 2017 | John Michael Godier | from his Patreon page -- "I am passionate about all science fiction, however with my own writing I want to create hard science fiction stories that blow people's minds but stay within the confines of the scientifically possible. Plus, I just want to spin a good old fashioned entertaining yarn in the process. In addition, I am an aspiring documentary filmmaker and maintain a science and technology based YouTube channel showcasing interesting and unusual subjects from the realm of hard science and futurism."

"But I am not really willing to accept your premise, because it may well be that the means of communications they have are of a kind that we do not know how to receive, and that they would not have the means of communicating with sufficiently powerful radio or optical signals. That is something which, technologically, is too difficult for them but they would have some other means we would not recognize." -- Thomas J. Gold, 'Communication with Extraterrestial Intelligence' (Sagan, ed)

"To consider the Earth as the only populated world in infinite space is as absurd as to assert that in an entire field of millet, only one grain will grow." -- Metrodorus, 4th c BC Greek philosopher

"Heaven and earth are large, yet in the whole of space they are but as a small grain of rice. How unreasonable it would be to suppose that, besides the heaven and earth which we can see, there are no other heavens and no other earths." -- Teng Mu, 13th c AD Chinese philosopher
