    I think there is no doubt about it. For no matter how unlikely the earth and its living things may be, the size of the universe guarantees that there must surely be life elsewhere. However the very neccessity of resorting to the size of the universe (for we seem to be uncovering evidence that the earth is unlikely indeed), also guarantees that physical contact between such intellegent species is quite unlikely, especially if you accept the realities of relativity.

    BUT.. Thinkin of those billions of years the earth still is there. It is unlikely they would be at our state of development.

    No signals were detected in space yet. and what is 1000 years in 10 billion years? not a lot. anyway.. we can look at intelligent life around our own planet for like half of our milkyway. Nothing has been found.

    I bet we're the first species that uses radiotechnology. Or there is less than 1000 years between us and them.

    but that's just a theory.

    One of the side issues in Stanislaw Lem's novel "Fiasco" was the existence of a "contact window", when a alien planet was neither too primitive to be useless to contact it nor too advanced to suppose a threat in case its inhabitants were violent... this added to the travel time at relativistic speeds, so a planet's progress had to be foreseen in advance as to establish when the contact mission should depart as to arrive to the planet within the contact window...

    (spoiler warning!)












    (spoiler warning!)


    ... then, after all that care, it turns to be human in the contact expedition who are below the contact window, as they end destroying the civilization they aimed to contact... fiasco!

    It is all but impossible to contemplate these issues without indulging in some form of centrism. Thus, the opening post considers the possibility of other planets with other life forms, and huge cities.

    At the outset the poster is assuming:

    a) Life arises on planets, not in space.
    b) Life consists of individual entities, rather than a single cohesive organism
    c) Life develops a technology
    d) Therefore, by implication, life evovles intelligence
    e) Life is, on some scale, cooperative.

    Zwolver makes some of the same assumptions and additionally:
    a) Assumes a desire to communicate

    Though (s)he very astutely notes that they may be attempting to communicate by means other than radio.

    In short, when considering the character and activities of aliens we should thoroughly contemplate the meaning of the word alien for quite a long time.

    In a universe of infinite possibilities I suppose there is a chance something similar to our planet may be out there. The odds of finding it however remain incalculable.

    If there is a species out there I would be happy and worried.
    With mankind’s temperament and history I don’t think we are ready for any type of contact yet, who in their right mind would want to know us :wink: ,

    and all of this history is being broadcast into space for them too see.

    The attenuation of signal strength over distance means that unless they are very close in astronomical terms they will not be able to detect the braodcasts.
    [Even if they do, their subsequent invasion fleet will be designed to deal with entities on a par with the characters in I Love Lucy. This will leave them ill-prepared to handle a civilisation that produced Friends.]

    I do not accept your notion of "infinite" possibilities. However, let me assume that you do. In that case, if there are really "infinite" possibilities, then it is clear that the probability that there is no life in the universe other than our planet with at least the same degree of development as our planet is zero, by your the definition of "infinite".

    I think that there is life out there, which is both more primitive then us and more advanced. also think that life may have devoloped on planets that are extremely different, if silicon lifeforms are possible. I also think that it could have also grown on a mass of intergalactic dust.
