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

If they broadcast at this moment we would receive the signals eons into the future.

I think it is 4.5 billion as the evolutionists tell us, want us to believe. Where is all the space dust, the dead stars and all those humans that have been procreating for millions of years, including all the primates, plants, coccolithophores, and sugar bears? Where are they? Buried on another planet no doubt.

“.... but the odds that we are the only advanced life that exists or has ever existed in the universe is rather remote”.

I agree.

I bet there is some form of a galactic notice like a pilots NOTAMs to avoid our solar system. Too immature and stupid.

Exactly.

It’s a damn long session in the chat room when it takes the other civilization 2.6 billion years to respond to a simple question.

It’s not that advanced civilizations have not existed or will never exist, it is the improbability that they exist at this very moment and could communicate or provide any sign of their existence.

Yep. That's a key point. If you assume they are roughly equally spread out over distance and time it is more understandable that we might never be able to detect another civilization. In my book that is good. Probably nothing good would come out of alien contact. It is as if God purposefully kept civilizations separated.

“To believe in this stuff, one must eliminate God.”

No. The exact opposite in true.
If were we ever to communicate with ‘aliens’ they may also know Christ and that would prove the existence of God.


That’s an excellent point.

Any group of ETs who have the power to get here would be a formidable threat. I just prefer they stay where they are. Remember when they get here the will eat the fat ones first! I happen to be a few lb to the plus side.

In 1974, I did a scholarly study of the existing literature on SETI and exobiology. My conclusions then were that there was a mode of 800 alien intelligences in the lifetime of the Milky Way Galaxy, and a 20% chance that we are going to be the only emerging technological species, assuming we get back out there and explore, and don’t blow ourselves up or get whacked by a supernova, etc.

Note that this says nothing about non-technological life in the galaxy, and assumes that the reports of ET are incorrect to date. It also doesn’t take into account Hugh Everett III’s Ph.D. thesis - which postulates an uncountably infinite number of branches to this time line. If one adds on my addendum to Everett, that crossovers must occur, then life is abundant, and we cannot destroy all life.

But intelligent life, technological life, is a different kettle of fish.

What complete horsecrap. Who says any of these planets are “habitable” just because they have water? What about temperature, atmosphere, mineral content, concentrations of toxic material. I realize alien life could be anything right down to silica based instead of carbon based, but this article is still complete 100 percent BS. There is no evidence whatsoever that any of these planets could support life of any kind, but lets just pull something out of our ass and play make believe.

What a load of crap.

Lol.

That reminds me of the old Twilight Zone episode “To serve Humans”.

Different things make sense to different people. To me, the Universe and the existence of life is non-random. Based on that premise, it makes no sense to me to come up with a guess about the probability of other life in the Universe. That is mixing apples (my non-random premise) with oranges (probability of random events). As for me, I have no problem at all believing that the entire unimaginably vast Universe is just the background or stage for the incredibly important, almost unbelivebaly important, saga of humanity. More specifically, if God cared enough about mankind for the Incarnation etc, why would it be so hard to believe that the Universe is or may be just a background for this greatest story of all. Just my two cents.

Interesting thoughts, but not much pertinent to reality.

They are advanced and live underground.

Just kidding.

The “underlying concepts” are mathematical postulates that pretend that certain individual attributes - liquid water - are, or relative distance from a sun, or size & possession of heavier elements and carbon, are all on their own “evidence” of “possible life”, when we have no empirical evidence even in our own solar system that those attributes have produced life.

It is guessing game being done with even less fact-based-assumptions than the “global warming” models.

Given the state of human understanding of “solar biology” to date - pre-K you’d have to call it, the idea that “astrobiology” can today speak with any authority on the self-named “branch of science” it has taken, is at the height of human intellectual arrogance.

Humans will learn much more about this solar system and finally a long time afterward reach beyond this solar system with some form of exploration of other solar systems (maybe 1,000 years form now) before any humans MIGHT be able to speak with any authority on something such as “astrobiology”. Until then it is all pretense based on assumptions that pretend to know more than we know.

It would be a different world, literally.

I have read about planets in a Goldilocks zone that have a day that lasts 2.5 earth hours and a year that lasts a few earth weeks.

If there are intelligent beings that live there, do they get every thing done in that two hour and a half hour day?

When could they sleep?

Heck, I know people that spend three hours on their work commute each day?

How many civilizations are in existence “ right now”? Does “ right now” have any meaning at all when you factor in relativity?

Good point. "right now" to me means our time period - 2017. This means any detection right now pertains to a civilization that may have lived 1,000 years ago or 100,000 years ago depending on the distance. I don't think they will ever have a detection. I think the distances are simply too great and the probability of detecting one in our small window of time is just too small.

Life - seems more than probable. However, that doesn’t mean civilizations.

Google the Fermi Paradox. If advanced civilizations were that common we could literally watch stars disappear in the night sky.
