Do we need to discover life out there  ?

Do we really need to discover life in space ? What will happen when we do ? I mean , they`re not going to speak any of our languages. What happens if they are so tiny we can`t even see them or maybe they could even survive without water or oxygen .!!! What will we do if they are carnivore and could start eating us or hunting us down!

    Re: Do we need to discover life out there  ?

    I'll reply to your questions one by one.

    1) Do we really need to discover life in space ?
    No we don't. But, to pursue knowledge we do need to search. And if we don't pursue new knowledge, what is then the meaning of life? To wait for the next commercial?

    2) What will happen when we do ?

    Probably very little. Most stars (and thus most planetary systems) are very far away. To just get a reply on a simple question would take an enormous lot of time. Hundred of years - and when you get the answer, who is left to listen for it and who is to remember the question (and: whoever might live out there don't speak English [reality isn't a Hollywood movie] so they would probably not understand what it is all about). So, you might get some signals some thousand years from how, but then...

    There might however be a positive  effect here on the Earth, and we we might get another win for knowledge on behalf of the religious fanatics.

    2b) I mean , they`re not going to speak any of our languages.

    No they are not. Our "messages" is just "plain" mathemathical messages that is very unlikely to have been created by chance. We don't even ask something! We just tell them that there is somebody out here (which we can do for a short period of time before all this planets' resources have been consumed by the zombies that watch the commercials).

    3) What happens if they are so tiny we can`t even see them or maybe they could even survive without water or oxygen .!!!

    Well, they are not so tiny that we can't see them (you should read Douglas Adams and consider the massive armada that was sent out from some planet and when they finally reached the earth the whole armada were accidentally swallowed by a dog).

    When it comes to water and oxygen, I want to divide my reply in two.

    3a) Water: I doubt that there could be any form of life that could flourish without water and I also doubt that any environment completely free of water could harbour life (nothing live inside water-free minerals, for instance).

    3b) Oxygen. There are life-forms that only survive in an oxygen-free environment on earth today.
    4) What will we do if they are carnivore and could start eating us or hunting us down!

    This question is not only anthropocentric, but "tellusocentric". What does "carnivorous" mean for an alien life form? You mean that they have "meat" at home? Think before asking!

     

    And, I'm well aware of that this might have been a troll - but what if it wasn't?

      Hi Episcophagus I wasn't going to take part in this discussion but you said some things that I couldn't resist! For example:

       

      "1) Do we really need to discover life in space?

      No we don't. But, to pursue knowledge we do need to search. And if we don't pursue new knowledge, what is then the meaning of life? To wait for the next commercial?"

       

      You mean your only purpose in life is to pursue knowledge???!!!  That's a very nihilistic philosophy!  I expect it was said rather tongue-in-cheek, but our beliefs, our "philosophy of life", usually determine how we live in practice; and even how we "do science".  And that is a serious matter.

      2b) I mean , they`re not going to speak any of our languages. No they are not. Our "messages" is just "plain" mathemathical messages that is very unlikely to have been created by chance. We don't even ask something! We just tell them that there is somebody out here...

       

      Indeed, “very unlikely to have been created by chance”!

       

      I was reading an article about recent discoveries on how DNA - which could be called a kind of living “mathematical message” - works.

       

      Unlike the original simplistic understanding of “one gene makes one protein”; it is actually so unbelievably complex, with layer upon layer of “meta-information” (information about information) that even experts in the field struggle to get their heads around it.

       

      Much of the meta-information – including (if I remember rightly) the DNA code itself - is encoded onto what was originally naively called “junk” DNA.

      But even with this very clear message that there is indeed “somebody out there”, many on this forum manage to believe that all life, and the universe itself came about by chance???!!!

       

      3) What happens if they are so tiny we can`t even see them or maybe they could even survive without water or oxygen .!!!

      Well, they are not so tiny that we can't see them (you should read Douglas Adams and consider the massive armada that was sent out from some planet and when they finally reached the earth the whole armada were accidentally swallowed by a dog).

      When it comes to water and oxygen, I want to divide my reply in two.

      3a) Water: I doubt that there could be any form of life that could flourish without water and I also doubt that any environment completely free of water could harbour life (nothing live inside water-free minerals, for instance).

      3b) Oxygen. There are life-forms that only survive in an oxygen-free environment on earth today.
      4)

      In the matter of things like “aliens”, ghosts etc, even some otherwise clever scientists are so very gullible!

      Yet actually there are “aliens”, some of them very hostile and damaging to us, that require neither food, water, oxygen or anything else in the material universe.

       

      But that’s for another time maybe.

    We need to search for aliens or bacteria as it shows there is a new species rather than our own. If God made the universe he would have made other creatures as well. It is strange that we are the only planets that has life. Why is there so many planets and only one has life.

      How do you know what God would have done?  We can only go on what God says he did.  The Biblical account fits the observed facts very well - much better than Evolution - but says nothing about life on other planets.

       

      If there is life elsewhere it's an interesting thought, but probably not our business.   It could even be dangerous.  As I said: ...actually there are “aliens”, some of them very hostile and damaging to us, that require neither food, water, oxygen or anything else in the material universe."

       

      These hostile “aliens”, sometimes called “fallen angels” or demons, would be delighted to give us "alien encounters" if we are foolish enough to seek them.  They have no trouble disguising themselves as “more evolved” beings from other planets, “spirit guides”, good angels or even your dead granny!  Or anything else that “floats your boat” as they say.
