originally posted by: neutronfluxThere could be intelligent life 100’s to 1000’s of light years away broadcasting for the first time this very second. If their transmissions were even powerful enough to be detected on earth, it would still take 100’s to 1000’s of years before we would receive the transmissions.
If the race was telepathic, they may never develop a detectable form of communication to us.
Since instant space travel is not a reality. How else would we possible detect intelligent life 1000’s of light years away than by transmission.
I agree we have found no evidence of extraterrestrial life. But there is no evidence life doesn’t exist in other places in this galaxy. Or the numerous other galaxies. And we may never know one way or another.

And don't refer me to the magnitude of the problem. I'm a 62 year old Math teacher that teaches Physics (sometimes) on the side
Nice false authority. I’ve seen bar flies piss away more intelligence and creativity than you will ever have.

What are you rambling about.

If only a quarter of the known galaxies produced one intelligent species each, that is still 25 billion intelligent races......
There is no evidence that (fill in the blank) doesn't exist in other places."
Think about the above sentence. Ponder it. Discover the meaning of what it tells you.
And don't refer me to the magnitude of the problem. I'm a 62 year old Math teacher that teaches Physics (sometimes) on the side.
I told you you have to assume the coincidental existence of alien life during the same epoch of the universe we are in now. The very magnitudes you're talking about make the existence - during the same time period
And that doesn't even include the very real fact that, although several (a tiny minority of) known exoplanets are in "the Goldilocks zone," life can't actually exist on the vast majority even of those.
How Many Habitable Planets are Out There?

Planet Candidates
While data analysis is still underway, results from the Kepler mission have revealed thousands of planet candidates. More than three thousand have been confirmed as planets, and some of them are orbiting their host star in the so-called "habitable zone". That's a region around the star where liquid water could exist on the surface of a rocky planet.
The numbers are encouraging, but they only reflect a small part of the sky. That is because Kepler did not survey the entire galaxy, but rather only one four-hundredth of the sky. And even then, its data only indicate a small fraction of the planets that could possibly exist throughout the galaxy.
Can you now see my point? Nothing I've said here would change even if we had instantaneous space travel.
And beyond all that, exactly what is the difference between there being no intelligent aliens and there being no intelligent aliens we will ever know about?

What question is that? For a “math” teacher, you sure do ramble on pointlessly?

Again. Why would I care you are a math teacher?

What logic is that. Either something exists or doesn’t. Because you cannot perceive something doesn’t make it wink out of existence. Are you sure your not a flat earther.
It doesn't work like that. You can't assert the existence of something with no evidence whatsoever.
.
You can only talk about the likelihood.
So, it seems that you can't answer the question, and you don't understand my other point:
"There is no evidence that (fill in the blank) doesn't exist in other places."
For weak-minded buffoons, that means that we can substitute any term - such as "pogo stick riding ducks" for "intelligent aliens" and not lose one whit of logic.
And beyond all that, exactly what is the difference between there being no intelligent aliens and there being no intelligent aliens we will ever know about?
There is ZERO evidence of life on any evidence laney other than Earth.
That’s how science works, you build a hypothesis based on the current available evidence.
