But if there were, wethey wouldn't visit this planet nor use it's primitive calculating machines for communication.

4. Sure they exist
It's a big universe and I doubt we're the only intelligent life form in it.

That said, I find it unlikely that they have visited us. The distances between worlds is far too vast.

76. That's exactly how I feel about it.
The odds that we are the only species capable of interplanetary travel are small, I think, given how large this galaxy is, let alone the universe. But unless those other species have attained faster than light travel, it's a long, long damned way from here to our nearest neighbors.

6. Yes, but ....
a) there can be life out there but it may not be highly intelligent life like us.
b) I don't think they have arrived here on earth even if they are highly evolved.

Now ask me what I think might exist on our earth plane but in different dimensions.

7. I think that we get two separate ideas mixed up.
Edited on Wed Jun-18-08 06:02 PM by Mountainman
People talk about UFOs and as proof they say that there must be life on other planets. I think there is life on other planets but that life isn't traveling here. So does belief in extraterrestrials mean belief in life on other planets and that life is visiting here? If it does I don't believe in them.
And I have asked this so many times. Where is the physical evidence that other life forms have visited us? Where can I go right now to see it and touch it. It doesn't exist. There is no proof that we have been visited by other planets. We have only what people say they saw and what they saw cannot be explained. So it is called extraterrestrials. There was a story long ago about tribe in South America that had built a statue of their god. It was in the exact shape of a Cessna 172. They could not explain what they saw so they said it was god. Very similar thing with those who say they saw UFOs. They can't explain it and surely they will not worship it so they give it a description that none of us can prove or disprove. IMHO.

115. We don't know that for sure
We have no clue what form any other beings might take... I suspect there are life forms in every stage of development. We could have been visited many times by creatures who exist in another demension... or whose molecular structure moves at a much different rate than ours. They could have ultra sophisticated telescopic devices that don't require them to get anywhere near us. We're dirty, disease infested, violent creatures. Best keep a distance:) "We" may be keeping others from letting us know they exist.

There is just too much we don't know. But there are too many billions and billions of stars and planets out there... we'd be naive to think we are completely alone in the universe.

9. How long since Western science learned of galaxies, and how large and old the Universe is?
And such things as the theory that neutron stars may be single molecule strangelets? Our understanding of the Universe has grown exponentially in the last 100 years; imagine the next 100. Man could not build a flying machine 100 years ago, right? When was that pesky Wright Brothers flight? A mere 108 years ago? Americans only recently stopped keeping human beings as slaves (unless you count Republicans and their corporations). So much has changed so recently, how much more can change?

There must be more in the cosmos than we can dream of. At least two major spiritual traditions state the existence of life elsewhere, both of positive and negative polarity. They know more than I do so I'll defer to them until proven otherwise.

Intelligent, even. And I'm sure there are some, somewhere very possibly in our own galaxy, who are wondering the same thing at this moment.

Now, have they been here? Almost certainly not, with a dash of "almost" and huge huge helping of "certainly not".

Carl Sagan said it would be presumptuous (stupid?) of us to think that in this entire universe of "billions and billions" of stars, that we are all "star dust" and it's stupid to think that we are the only ones here.

Just look at Mr. Spock! Jeez, at least we know there are Klingons. And Romulons.

103. The creation of the Earth, and the life on it, is not unique
the universe, as far as we can analyze, is basically made up of the same elements which act and interact similarly. Life on Earth, even to this point, occurred relatively quickly. I'd say it probable life exists elsewhere, what's interesting is what evolutionary timeline have they achieved?

40. Best way to view the HUDF
The full image mosaic is a 60MB download and won't display on your machine unless you have at least 110 megs of free RAM.

The Ultra Deep Field is the deepest view into the sky by humankind to date. The ten thousand galaxies that are visible represents just one thirteen-millionth of the total sky. This is comparable to a postage stamp viewed from more than twenty yards away.

http://www.aip.de/groups/galaxies/sw/udf/swudfV1.0.html

Drag the green circle to pan around the whole image.

33. The evidence is right here on earth
It isn't like we're speculating about the existence of fairies or unicorns. We have the proof of life having developed on earth when given a certain physical environment. It wasn't magic, it was biology and evolution. If you can find it here, absent the proof of a certain absolutely unique and divine intervention, you can assume you can find it elsewhere, if given the right environment. If you find a million planets in other solar systems with an environment appropriate to the development of life and don't find life there, then that becomes a very unusual scientific puzzle.

"you can assume you can find it elsewhere" ... but see that won't fly in a court of law ..... hard facts ..... evidence .... assumptions won't work as proof. But unfortunately I haven't the capability of going to another planet and kidnapping an 'alien life form' at gun point and bringing um back here like some would have us do before they open their minds to the possibility's. Yeah I can go out to my backyard .... dig up a bug .... bring him in here, scan a picture of him, even video tape him/her .... and send it over the internet ..... clothe, bathe, feed, and present the bug before a jury of my peers to prove he is real. No-can-do with an alien life form .... but I'm working on it ..... ;) .....

60. Scientists assume things all the time
It's what drives experimentation and the decision on what to investigate. Scientists assume that the same principles, such as the laws of physics and chemistry will continue from one experiment to another and from one part of the universe to another. If we already have proof that life exists somewhere, on this rock for example, we can assume that it MIGHT exist elsewhere if the same conditions exist. If we find evidence of primitive life having existed on Mars, are we then going to say, "well life has only existed in two places of the universe, but it can't possibily exist anywhere else'? And then if we find life on a planet orbiting another sun in our galaxy, are we then going to say 'well, it can't possibly exist outside of our galaxy as we haven't been there to see it'.

The question was not whether we know life exists elsewhere but whether we believe it does. The belief is based on the assumption that if it exists on Earth, it could very well exist elsewhere, too, provided we find an environment similar to those parts of the Earth where life is found, such as our deep oceans.

62. Good discussion ...... anyway don't miss the full moon tonight at it's rising !!!
Edited on Wed Jun-18-08 09:20 PM by doublethink
Seriously it's supposed to be 'HUGE' optically (illusion) speaking. :) ......... You know my problem with 'Science' as the way you described it is ... we only have our own 'existence' to scientifically judge anything from. In other words ... who's to say 'life ' can't form from anything but our own preexisting conditions here on earth? Our finite minds can only judge from what we know or learned in 'our reality' ..... (hear the twilight zone music yet?) So even if little ancient fish bones underneath the ice on Mars are discovered .. or microbes long gone, whatever .... maybe that is only relevant in our particular neighborhood of the universe ??? The farther away you get from the desert the less likely you'll find Lizards. :):):) ..... Really don't miss that full moon tonight at the horizon .. early ..... peace. :)

on edit: Of course if and when we find microbes, mini skeleton remains ..... whatever on another planet in our own solar system (Mars?) ......... well then common ..... those that say life isn't out there somewhere else ???? Oh boy.

on edit 2: just because I want you to know that yeah Science as it stands has no other possibility than to go out looking for life forms in our own understanding ...... somewhere in the universe. If I had to make the decision of that 'one square foot' to look for it when looking up into the sky .... (see post #20 to comprehend) it would be to your scientific exploratory model here.

27. I think virtually all scientists would disagree with you...
While no scientist will say conclusively that there is alien life as they have still not been able to find the evidence they need to firmly make that conclusion, given the vast size of the universe which is almost entirely unexplored by humans virtually every scientist would acknowledge a strong possibility that life does exist on other planets. They have seen planets through high powered telescopes which appear to have the conditions necessary to sustain life, they just don't know enough about those planets to know what if anything lives on them.

79. You know,
look at the images in post #20. Or better yet, watch this video... http://www.youtube.com/watch?v=fgg2tpUVbXQ which explains the images in post #20.

When we can wrap our brains around the fact that we (Earth) are no more than a speck of dust in this universe and that there are millions and millions of galaxies just like our own, each containing millions and millions of stars, each with the possibility of having planets.....well, it just starts to seem pretty silly to think that our planet, out of God knows how many that may exist in the universe, is the only one special enough to support life. Just one? Out of the entire universe??? Seems so extremely unlikely as to be ludicrous to think such a thing.

Just because we don't have EVIDENCE of it, doesn't mean it isn't still extremely likely.

82. No.
The evidence is everywhere. That there must be life. If there is here, it's out there. It would have evolved the same way. Everything we've seen points to millions of earth-like planets in the universe. And that's assuming no radically different forms of life.

As to whether they're here. Well, whatever. It's a higher than zero probability, unlike the chance that God talks to Bush.

24. I believe the sheer mathematical probability makes it literally impossible for there not be
some form of life on another planet.

To believe that this tiny ass blue marble floating around in the vast universal uterus is the only possible location for life to exist is the height of hubris.

The distances are just too vast and the possibility of any life forms finding us are just too remote for them to have ever been here.

28. It all depends on what you mean by "extraterrestrials"
Edited on Wed Jun-18-08 06:42 PM by Warpy
It's been pretty well confirmed that DNA exists "out there." Fossilized bacteria are strongly suggested in some meteorites.

However, bipedal apes that share our physiology and method of communication are much less likely.

The more the physical universe is examined, the weirder it looks. My best guess is that it's teeming with life, some of it undoubtedly intelligent according to our definition, but that the challenge for us will be to recognize it as such.

After all, we still can't communicate with the cetaceans, and we share a planetary frame of reference with them, along with much basic physiology.

34. Without a doubt.
I an not sure in what form that may be, but somewhere in this huge universe i am sure there is life. If you just do the numbers it's almost a certainty.

38. I'm sure of it, but I have no idea where they might be.
Unless we are in some kind of remarkable cosmic test tube I'd say the chances of our meeting up with them any time soon are near zero. Unfortunately, as more and more people realize this I think the end result is a turning back towards religiosity since Angels and demons can be imagined to be right next to us without all those pesky inter stellar travel and physics barriers.

44. Evolution is mindless, arbitrary, and pointless. It seems more likely than not.
The universe is a big place, and it's likely that there are more (many, many, more) universes. It's seems improbable that some sort of necessary soup to set evolution towards life only formed on this one insignificant little planet out of trillions of others.

Alas, it's also unlikely that our, not so successful, species will be around long enough to find out conclusively if there are other life forms out there before we disappear unnoticed and unmourned in an indifferent cosmos.

46. Zero times infinity
This is a situation that could be well approximated by 0*infinity.

The circumstances required for intelligent life to survive on a planet are very improbable. It takes exactly the right sized planet, with exactly the right temperature range, with the presence of liquid water, etc, not to mention how improbable the formation of life is. Moreover, even on Earth, intelligent life has existed for about 250,000 years (http://en.wikipedia.org/wiki/Human_evolution) out of the Earth's 4.5 billion years in existence. That is another factor of 1/18000. In effect, you could model the probability of a given planet having intelligent life at any given time as approximately equal to zero.

Yet, the size of the universe and the number of planets are so vast that they can be considered infinite.

To a rough approximation (assuming our answer is either going to be very near zero or very near one), you could say that the probability of intelligent life occurring on any planet at a given time is equal to zero times infinity, a quantity that is UNDEFINED.

In other words, if you just read this, I just wasted your time, because I could have summed this up by saying: "I don't know."

49. Yes.
I find it improbable, to say the least, that there is only one body in the entire cosmos that sustains life.

I also find it improbable, again to say the least, that a planet that sustains life would not be subject to evolution, and that sentient beings would not evolve.

I have no opinion one way or another about whether or not such life forms are now, or ever have been, within reach of earth.

51. Highly improbable that we are the only sentient beings
in the universe.

Whether they have really visited us here, is another question entirely. I vote No on that. Considering it took 6 billion years for us to develop on this planet, and we have not achieved interstellar travel yet... I doubt whether they have yet either.

54. Actually, I would like to belief they exist....
and when the evidence shows that life does exist outside of our Solar System, then I will take on that belief.

However, the Math is on the side of the possibility that it is very likely for them to exist. Because every star is a chance/opportunity for them to exist and there are more Stars in the Universe than there are grains of sand on every beach on Earth.

Whether they have visited or not is debatable. I have never had an alien experience of any sort but I'm certain there is other sentient life out there. On percentages alone it must be. Then again, none of us are really here anyway.

95. In all my years on this earth. I have witnessed phenomenon many times.
I have encountered ghosts and demons by the dozens. I have seen human will defy death. I've even seen a bigfoot. But I've never seen a UFO. Yet because of these other experiences with phenomenon. I can't discount the possibility of life in outer space. It only makes sense. The first thing that leaps out in my mind is the law of Micro and Macro. Anything that exists in Micro will also exist in Macro. I know ghosts to be real. It is believed that they occupy inner space. This would be the Micro aspect. Life in outer space would be the Macro aspect. So if there is life in inner space. The law of Micro and Macro dictates that there will also be life in outer space. It just seems more like common seance than the incredible. To those who say, Why haven't we found it or it found us yet? I don't think you truly comprehend the vast expanses of outer space. Traveling these vast distances is contemplated in terms of traveling at the speed of light for tens, hundreds, or even millions of years. It's called Light years. The distance light travels in one year. Outer Space is blow your mind big. So why not life on other planets? The bounds of probability are well within outer space. As for other life in Space contacting us. What if we are the most technologically advanced life in all of outer space?

I believe they exist because the universe is too damn big for them not to.

However I do believe in the speed of light and thus do NOT believe any ETs have visited this earth as the chance of intelligent and evolved life being close enough to visit is really remote.

97. The speed of Light doesnt matter
apparently now that we're pretty sure there are at least 11 dimensions, there are bound to be trillions of dimensions and alternative Realities.. So not only do "aliens" exist, but multiple copies of YOU exist doing all the things you ever wished you could do..

In an infinate Universe Everything is or will Happen, so I think it may be better for us all to Tune into that..

Since the 11th dimension occupies a space smaller than the area between you and your clothing, there's also a good possibility that the Aliens could fly right out if your Ass.. Yes, I'm smiling, but not kidding at the same time.. :)

One thing to consider, if you haven't heard, is that whatever happens to an electron next to you also happens to one A Trillion lightyears away, at virtually the same Time.. Some folks believe there's really only One Electron..

Makes sense if you think about it.. Real Fucking HARD :)
