    I'm not "tempted" to believe either way.

    Does such an evaluation actually hold up, in light of scientists discovering a black hole that was supposedly too large to exist within the physical confines of the milky way?

    If event 2 happens it will tell us there are 'only' two planets in the Universe with life forms as we know them. IMO stuff is growing and evolving all over the place but to capture empirical evidence remains the issue...

    Well, a discovery like that would draw into question the line of logic that seemed to support the argument.

    That's unlikely to invalidate much of anything else.

    I don't believe there is any other intelligent life anywhere else in the universe.

    I might agree.

    However, we really haven't even started to look yet.

    It's been a short time since we actually identified a planet that isn't in our own solar system. And, those exoplanets we have identified are so far away that we can't tell much about them - including whether they have life.

    My theory has always been "they came, they saw, and they rolled their eyes and left." I'm recently retired from teaching, and after reading what you said, I think you're absolutely correct.

    And then again, we tend to think of aliens that in some way relate to us in size, shape, intellect, and all that stuff. That might seriously limit what we're looking for when we look for aliens.

    There are well over a hundred billion billion galaxies and each one contains about a hundred billion stars. Most of these stars have planets. It is statistically impossible that only one of them had conditions permitting intelligent to form

    I think they know we're here. I think they're here now and probably have been forever. They have something like a Prime Directive but I think it only applies to letting us know they're here. They have no compunction about guiding us and often do so for their good and ours. They won't let us know of their existence and this is not only for our own good but because we are far more useful to them if we come to that knowledge on our own.

    If there are spacefaring civilizations, (and if spacefaring itself is possible they are a statistical certainty), then it stands to reason that most of them must be many years older than us since the Universe is billions of years old and there has been plenty of time for them to come about compared to our own relatively brief existence as an intelligent species. (This leads to the intriguing possibility of civilizations billions of years old, as far beyond us as we are beyond insects or even amoeba, yet still able to communicate with us, this may be where God comes from but that is just speculation)

    Probabilities are not evidence. Even if many planets (say 10,000) had the conditions permitting intelligent life to form that does not mean intelligent life would actually come into existence there. I suspect that the majority of planets where life can exist have nothing more complex on them than moss and sea weeds.

    Considering some humans and their behavior, moss and sea weeds would arguably count as more intelligent forms of life. Humans are the only species immolating themselves in the name of online challenges, or who are consuming laundry detergent for the same reason.

    It's not 10,000, it's 10 billion and actually 10 billion TIMES that again. Space is vast beyond our comprehension and past a certain point, the probability is indeed certainty. Once you have moss and seaweeds you will have intelligence given several billion years it is inevitable and unavoidable.

    Given the "Probability" that life developed in multiple locations just within our solar system, I believe your estimations to be quite flawed.

    I know there are billions of planets but a vastly lower number are likely able to have life develop for various reasons (hence my 10,000 number).
    And there is likely nothing "inevitable" about the development of intelligent life.

    And where is the evidence of that?

    Evidence of probability?

    "Indicators" are found in the many organics found off world and the understandings of requirements for combination/activation.

    The presence of "organics" in no way indicates that life actually evolved there. Much less intelligent life.

    1) Organic molecules are required for protein development.
    2) Proteins are required for RNA/DNA.
    3) RNA/DNA are required for life.
    4) Life in required for intelligence.

    It would seem the indicators exist.....in probability.

    Everyone has speculations about the 'development of intelligent life' away from Earth...and they are simply speculations. Therefore, it carries equal weight to speculate that the 'development of intelligent life' away from Earth exists throughout the Universe. We will never know until we actually know...

    On what do you base that claim?

    You have no way to know that. What is fantastically unlikely - mathematically zero in practical terms - are the odds that we are alone. This because there is nothing special about the planet, the solar system, or our local star. The building blocks of life are found everywhere. With the ongoing discovery of exoplanets, we are finding that planets are common to almost all stars. And there are trillions and trillions and trillions of them.

    Do you know how big a trillion is? Can you name ANYTHING else that is true, with odds of trillions to one against? No, you will not come up with one example.

    There is no good argument that can be made that we should be unique.

    I submit that anything with odds of trillions to one against, will NEVER happen. Show me one example where I'm wrong.

    The image of god could mean the particular quality of consciousness. We can create using consciousness. Andcreate marvelous things.

    I dont know where they hail from but some kind of superior intelligence have been navigating our skies since at least the 40s . Govt documents and thousands of military sightings and interactions prove it.

    If they have introduced themselvrs to our govt it has been kept hidden from the public.

    Highly unlikely as they would be nanotechnology and not be seen

    That's a far better guess given what we know today.

    There is so much going on here and our vision is so imprecise that choosing some other star system as the likely source just doesn't make sense.

    Intelligent ET's with technology we haven't even dreamed about yet, it's possible. Have they visited Earth in the past or even the president, possible again. These ET's may be so far advanced, they may look on us as we would a colony of ants. Why introduce themselves?
