    im with martin. i dont see how you can come up with a probability since we only know of life forming once.

    you can say that since we know there are near infinite planets with similar elements that its more likely, but i dont see how you get anything more than that.

    it seems perfectly possible to me that we are alone. and lord knows, i am not a creationist.

    and when i say "possible", i mean like anything is possible. maybe there are millions of planets with awesome creatures on them. or maybe just us. i feel like we are really stretching it when we make claims about how likely any of these things are.

    the fermi paradox is of course the idea that if there were intelligence, then why has it contacted us? and given that there are places in the universe older than earth, they might have had more time to evolve and create their contacting machines. but they havent.

    i know red is mostly quoting carl sagan's theories, but those are not necessarily accepted by the rest of the scientific community.

    I don't have a problem with people believing in evolution or creation. I can understand why both are believable and why both create doubt.

    My question is for those who DON'T believe in a higher power or an afterlife. If there's nothing after this...what's the purpose of living now? I've never been able to comprehend why people would tolerate life's struggles or waste time with insignificant efforts if we're simply pond scum.

    Once again I believe people are entitled to their opinion but I have a hard time trying to understand why living a ethical, moral, productive life would mean anything. I also can't see the value in how living a wild life would matter either.

    Either way, when you take your last breath it would be over...forever. If that's truly the case, what does living one more day, hour, or minute matter?

    That's only because we haven't traveled very far. It's not like we know that there is one live earth and billions of dead ones.

    Ok, your logic is moving, just keep it moving. You are already past the black and white martonian concept that says we either know everything or we know nothing. You recognize that we can often perceive a greater likelyhood between two possibilites. Carry that one step further. Perhaps we know a great deal . . . enough that we know that there is an exceedingly high likelyhood. The laws of probability suggest this.

    Just because there is no evidence of a thing doesn't mean that there cannot exist evidence of a thing. Evidence certainly cannot be found if we can't get anywhere to see it.

    However, this does not mean that we cannot investigate the probabilities of events outside of our observation. We know that life requires oxygen, hydrogen, carbon, etc. and have many observations of these elements existing elsewhere. We know that life requires liquid water and we have observed that planets orbiting a certain distance from a star have the right temperature to permit this. There are many parallel observations than enable us to make valid statistical deductions regarding the probability of life elsewhere based on the extent of the habitats and materials of life.

    We have no evidence of which I am aware for magical genesis of life or of any supernatural processes at work.

    So . . . if we accept that life is a natural process, then these processes are subject to the natural laws of probability and there is a very high likelyhood of life existing on other worlds. Else we are saying that life was "created" only on earth.

    The universe is unfathomably vast, obviously. The oldest parts are the furthest away while moving away further and picking up speed. An intelligent civilization may have emerged a billion years after the big bang and prospered for a billion years and it would still take 11 billion years for their signals to reach us.

    Plus you miss the point that is a major difference between intelligence and life. If we find life on other planets the overwhelming probability is that it is going to be microbiologic life.

    I have neither quoted a Carl Sagan theory, nor do I subscribe to any single scientific concept. You have no idea what you are talking about. What a shock.

    Why not, it is the small time that we are allotted here. If there is some supernatural destiny beyond death, I shall deal with that in its allotted time.

    I regret if you struggle with life in pond scum. I am jubilant and prosper with a life that is full and fulfilling. Sorry if I don't feel particularly suicidal.

    Why does a happy life have to mean "something" or "matter" to anybody but ones own self? I've never understood the quest for the "meaning of life". Life is what you make it. I make my life to be conducive to what makes me happy and content. Why would we do otherwise?

    I don't get it. If this life is all you get, why would you want it to end any sooner than necessary? What does "matter" matter?

    Life is a race. You run till its over, enjoying the entire experience, and being fulfilled at the achievement. I suppose you could just quit for lack of "meaning" and then I guess you certainly would not matter. But it makes little sense to me.

    I respect your opinion and I'm glad there aren't more people committing suicide or living for the day at the expense of others. I just have a hard time getting my head around why achievement makes sense if there's nothing else. To each his own. :thumb:

    Because what you leave behind matters, as well. I'm not talking about one's legacy or status or perceived importance. I'm talking about the impact you've had on others, your family, your friends, and in some cases, people you've never met.

    i approve of the word "martonian" and accept that it means when things are improperly defined as too black and white. i further propose that reddian analysis is when too many shades of grey are detected and presumed to be of value, merely for their greyness

    of course. nobody is saying aliens do not exist. we are saying that is pretty difficult for us to make statements about how likely it is. we dont know. thats what the martonian analyis shows.

    well, i dont even really buy that life requires those things. perhaps there is life somewhere else that is based on titanium or something instead of carbon, and there are aliens that breathe molten cesium.


    false dichotomy. we can acknowledge that life exists on earth while also acknowledging our ignorance of how common of an occurrence it is.



    i will certainly concede that simple life is more likely than intelligent life, although i have no idea if either exists on other planets.
