Do you believe in intelligent life elswhere in the Universe?

    True, but that sounds kind of boring.

    at what rate do you believe intelligent life occurs on planets?

    before we knew about other planets, we knew about our planet, and we knew there is intelligent life. so the ratio of intelligent life to planets was 1/1.

    then we learned about the rest of our solar system, but none of the others appear to have intelligent life, the ratio is now 1 intelligent planet per every 8 or 9 planets or whatever.

    how many planets do we know about now? 100 or so? now we are at 1/100?

    we know there may be virtually infinite planets out there right? so how do you know that the ratio of intelligent planets to planets that exist will not just continue to rise to 1 in infinite? since we started discovering other planets, not one has bothered to have intelligent life. what evidence do you have that one will be intelligent? how can you know exactly how rare we are? all we know is that the more planets we find, the more rare we appear.

    why dont you explain the statistics/probabilities i apparently dont understand? teach me how the sample size of 1 is sufficient to draw a conclusion.

    if you have an infinitely large bag of m & m's, and you reach in and pull out a plaid m & m, then pull out 500 straight brown ones, at what point do you think you are due for another plaid one, if ever? the answer is that you have no idea.

    Again, Douglas Adams put it very well:

    When I was about 14 or so, we were paddling pirogues through the marsh ehing my house right around dawn (in route to duck blinds). The sky lit up (quick as lightning, just filled p the whole sky) a bright blue, and me and my 2 buddies heard a rather loud "snap" sound. All I saw was a trail of smoke that dissipated into nothing. Scared the chit outta me to say the least. That evening, I heard on the radio that it was some sort of space debris that entered the atmosphere, but I was never sold on that one. For some reason, it just seemed like more than that. Probably just because I was paranoid as hell for about a month after.

    Martin, for someone who says this thread is a waste of time to talk about,you sure have made a lot of posts.In my opinion, there are only three ways to explain life on this planet.The first is a Creator,second would be evolution,and third would be aliens planting us here.,so I do believe it is at least interesting to discuss .I happen to fall into the Creator camp.From reading your posts it appears you fall into the evolution camp.The Miller Urey experiment at Johns Hopkins in 1953 is supposed to prove that Evolution is correct because they were able to create amino acids which bond together to form protiens ,which are the building blocks of life.They took the gasses thought to be in earths atmosphere and put an electric spark to them to simulate lightning and did in fact create amino acids.What they don't tell you about this experiment is amino acids come in 2 forms left handed and right handed.Life is made up exclusively of left handed amino acids .Right handed and left handed together bond,thus no life.Right handed alone,no life.They created sludge,that is it.Now I suppose you can say that over the course of billions of years that eventually the lightning will produce only left handed amino acids.This is the famed a million monkeys typeing on a million typewriters for millions of years and eventually one of them is going to crank out" War and Peace".I would say that believing that shows a pretty good deal of faith.My opinion is a bucket filled with pennies .Everytime you reach in the bucket and get a penny tails up,that is a left handed amino acid ,heads up is right handed .Could life have happened this way .Sure ,with an intelligent being reaching into the bucket and picking out tails only.In fact ,I would put Evolution far back in position three barely making the list.

    Obviously ,I am a believer in a Creator,but aliens or ufo's would not change my beliefs if they do exist.A few ufo incidences and my thoughts on them .1895 crash of ufo in dallas texas=hoax.1947 ufo crash in Roswell New Mexico= project mogul spy balloon. The ufo incidences that I think have at least a small degree of credibility are the Rendelshem Forest ufo case in England ,the 2000 Illinois ufo police chase and the Travis Walton case because they all passed polygragh exams.I suppose I give military people at Rendleshem and police in Illinois more credibility than the average joe on the street,especially since there are audio recordings.A few other stories that are hard to believe but interesting are Jackie Gleason and Richard Nixon visiting alien bodies at homestead air force base http://www.rense.com/general70/gleason.htm and one other involving a young math whiz rocket builder.I will see if I can find a link to it and add it.

    The chirality problem has been studied many times since 1953. It is important to understand that only synthetic organic chemicals contain left-and-right molecules while naturally occuring life contains only L-amino acids. Just like science has created elements that do not occur in nature, such is the case with the synthetic organic chemicals.

    Reza Ghardiri has suggested that primitive precursor molecules capable of self-replication may have amplified the production of their own kind. His experiments indicate that, once formed, the homochiral molecules (left-handed) acted as templates, accelerating their own replication. The heterochiral (paired) molecules, in contrast, did not use this ploy to compete.

    I can't see how these experiments suggest Creation over Evolution to you. The whole process is extremely evolutionary. The peptide system has life-like characteristics: it can induce self-replication, select for molecules of the same handedness, and avoid the accumulation of errors. This suggests that self-replicating peptides could have played a crucial role in the emergence of life on Earth. Of course, why life chose to put all bets on L-amino acids is still a mystery.

    i never said this thread is a waste of time. use quotes if you want address what i say.



    that is a totally different question.


    it isnt "millions" of years. it is "infinite" years. that is the whole point, to explain infinity. also that is totally irrelevant.


    don't sell yourself short.

    I believe that there's probably intelligent life someone else in the universe. They may not be as evolved as us, or they may be more evolved - or both.

    As for martin, he hates to speculate on things that cannot be backed up by science. I don't know why. It seems to me that through history most science has started off as guesses without any proof.

    i dont mind speculating on things without proof. i love doing that. but there is a difference between no proof, and no evidence of any kind whatsoever. drunk lunatics and photos of frisbees do not count.

    maybe, but not guesses without any evidence. and saying "i believe there is intelligent life" is not a hypothesis, it is a conclusion.

    i think there is a lot of why and how that needs to be asked before we draw conclusions.
