    Could there have been a civillization before us that was just as advanced, or more? If there are other planets out there that have civillizations like ours, and there is a lifetime is it possible that no civillizations lives long enough to reach the pont of contact with other civillizations from other planets (IE, they die out before they have the technology to reach out)?

    I have moved this to general discussion.

    There is the possibility but so far no evidence.

    Lets talk about the evidence. With the materials we use today, can we create a model timeline of how long after the fall of a civilization like ours that the evidence would remain?

    just as advanced as us? then wed see rests of them in orbit and such. it would indicate if any civilization had existed before us it werent space faring in anyway.

    for today its thought a advanced civilization have a lifetime of 100 tousand years. i think its more like a million minimum but thats my own thought. and we have seen to fossiles of any biengs capable of using tools except us and that. so far evidence says no we are the first civilization on this planet. but we most likly wont be the last if we die out

    I think it was Isaaz Asimov who wrote a story about an advanced civilisation that just 'dissappeared' - it turned out that many millenia ago they had conquered all 'ills' [genetically] so there were no more health issues. Over the course of time all knowledge of medicine was lost, since nobody ever got 'ill', nobody bothered to keep the information, it was discarded finally when nobody understood it!. Then along came a small meteorite with a 'bug' on it.....

    There is also proof through DNA that there was a population bottleneck 70 thousand years ago in the human race. The Toba catastrophe theory suggests that the population was reduced to a few thousand people.

    And for the post above about things orbiting the earth. Satellites generally last only 7 to 13 years. So then the questions is what happens to the material (evidence) after it falls to earth?

    That's odd, the moon is a satellite of the earth, and it's moving away!

    As we know we get many pieces of space junk each day and the contenats will have changed maybe the ancient city of 'atlantis' could just be the remenance of an ancient civilisation hundreds of miles down in the ocean.
    I don't believe any of this myself but people believe that the ancient eqyptians had alien help building the pyramids if we are talking about people before us maybe these aliens could have lived here and returned. However as we have no evidence this could be as true as harry potter. :wink:

    This is true, but man made satallites fail to function, after that I dont know what they do with them. Plus, maybe their version of china back then made a satallite missle and took them out!

    If you reckon before us there was an intelligent race on earth that could throw things into space forget it. They would have prodded about on the moon, and we would have found it. The lunar surface in places is almost as old as the moon itself, there is no erosion so anything left would still be there!

    We are getting off track.. Even if there is only a one time civilization on planets like ours.. The lifetime of such a civilization would not allow us the ability to reach a point where we would be able to communicate, or visit other civilizations.
    You figure it takes all the right conditions to support life, then the conditions would be similar in other systems. If they are similar, then there could be a common catastrophe timeline with those other planets. With that said, even if there is life out there, we may never know as we will never be advanced enough to get there.

    There is almost certainly life out there, there may be intelligence as well [god knows there's little enough on earth], there is the possibility also that we are the first [higher form of] life. Remember for 90% of the earth's life it was only 'inhabited' by single cell organisms, if it were a pure fluke that this changed, it is possible there is NO form of life anywhere else other than 'single cell' forms.

    Now your talking! But, I do find it hard to believe that the "fluke" could only happen once in the universe considering how many systems are out there. Im sure its possible though.

    well it did not happen here for 4 billion years after the first life, that suggests it is a rare occurance, if it typically happens after 15 bn years then would not happen in the life of most stars capable of supporting life.

    Could be another point. Within a 15bn year lifetime, its not possible to abtain the technology to travle at light speed within the time frame. For us its 11bn years of existence. For other systems it could be more or less. If we use time as our basis, then you could say that no one has the ability in that time frame or we would have seen other beings visit us.

    Who knows? - my own feeling is that intelligent life is probably rarer, much much rarer than people bandy about. I hops it is anyway, contact with another civilisation is not one of my personal wishes.

    What do you really think would happen if we were to meet another race?

    Firstly the Amreican President would mis-trust them as he would have no intelligence about them, then he would try and 'spirit one away' for testing, then he would seek to have developed a human tolerant alien killing virus which, he would sparay around like agent orange in the Vietnam war.

    His adversary upon realising this would retreat to the moon point his 'zapper' at our little planet press and hold the 'fire' button and send the pictures back home.

    Then they would creat the UP (United planets), this would be a cover up for Galactic Economy, or Galacization, or new Galaxy order as it would be called at first.

    And then all the call centres would move even further away, so maybe blasting them is the right thing after all...

    Places like Mars would have no envirnmental laws, so they could build large manufacturing plants there and outsouce to the marsions

    the word "intelligent" is subjective to us...

    we may be primitive to other life forms, even to degrees we feel most animals are to us. my thoughts are life exist or has in most places where planets orbit a star. if time grants this life to evolve, then intelligence can evolve and to degrees un-imaginable by us. what triggers intelligence. the key being what causes this. if man had evolved or been 100 million years ago, or even the known 3 million years ago, the trigger to reason happening then our civilization could have been much further advanced.

    Hey, for 4.0 billion years there were only single cell life forms. Of the hundreds of millions of species of multicellular life only one has ever developed the ability to to explore space, what more proof do you need that these things are rare, very very rare.

    But even if there are more “intelligent” beings, I still think there is a small window (relative to the life of their planet) in which these beings have to develop to where they have the ability to travel the stars.
