For Calliban re #25
Thank you for your thoughtful post about probabilities of an alien civilization taking an interest in humans, or Earth, or even the Solar System.
I ** hope ** the early excited speculations in China were removed by sober authorities who do not want China to become associated with the occult element in the United States.
Work by serious researchers ** has ** been going on in the United States for many years.
Hopefully whatever signals were picked up by the Chinese radio telescope will receive the same attention.

With scientists finding new and bizarre exoplanets each year, searching for life as we know it might be too narrow a parameter.

Would It Be Possible To Detect Dead Aliens or even on Earth Dinosaur Lizard men who just got up one day and left for the stars, after Millions of Years passing is there anything left behind we could see that shows An Ancient Industrial Civilization?
What If Earth Hosted An Industrial Species Before Humans?
https://www.discovermagazine.com/the-sc … n-on-earth
Inspired by a Doctor Who episode, the Silurian hypothesis asks if there are traces of an industrial civilization before humans on Earth.
Are Humans the First Civilization? The Silurian Hypothesis
There are over 7 billion people living on the earth right now. Tens of millions are born and die each year. Every single one of us leaves signs of our existence in the air, water, soil -- even space.

But these signs won't last forever. Our buildings will be gone in a few hundred years.

Barnard’s Star is a small red dwarf just six light-years from Earth. Despite its proximity, it was only noticed in 1916 when E. E. Barnard found it had a particularly high proper motion.

In a recent study, mathematician Daniel Vallstrom examined how artificial intelligence might be similarly motivated to avoid spreading across the galaxy, thus explaining why we haven’t seen them either!

Today's Internet feed included a recent article on SETI by a professor from the University of Arizona
https://www.scientificamerican.com/arti … wtab-en-us
Given such seemingly long odds, one might wonder why we should bother looking. Cocconi and Morrison had an answer for this right from the start, noting in their 1959 paper that “the probability of success is difficult to estimate; but if we never search, the chance of success is zero.” Consider this: If just one of these searches were to yield positive results, that would suggest the universe is truly teeming with life. If all the results were negative, that would be the best empirical evidence yet that we are the winners of a cosmic lottery, inhabiting a profoundly precious planetary oasis in a vast galactic desert. If scientists could show we’d hit such a massive jackpot, might we take more care with our world and one another, lest we squander it? I like to think so.
