This is a topic that we have long wondered about – do aliens exist and if so have they communicated with us or attempted to? Everyone has a strong opinion on this topic so I expect you will all be very vocal. It would be great if you can give examples from your own life about the moment you started to believe, or stopped believing.
When answering this question, be sure to give us your reasons for your answer – it gives us a chance to debate!
Do aliens exist and have they visited earth?
My answer is no – I think that if aliens existed and had the knowledge to travel to earth in UFO’s – they would not be trying to hide from us – they would communicate. Also, if logic says they must exist, surely logic would then also say that there must be somewhere a race so advanced that they could communicate and would have. Having said that – I think it would be very cool if they did exist!





















Mathmatically, they must, and for the same reason, they haven't been here…yet. THe place is just too big!
You missed some variables in your probability equation. Must be a cause of shallow observation before you wrote it with the constants, operations, functions …
Ditto. Although I find it rather self-centred and hard to believe they resemble us in any way.
no.
If aliens do exist, I personally think we’re screwed. It won’t be a matter of them being hostile or peaceful, but look at what happen to America’s Natives when everyone was colonizing the new world. Two civilizations that had not had contact for thousands of years come together and one is ravaged by disease from the other.
It will be like war of the worlds for either us or them and one civilization will probably be wiped out by a disease that comes from our world or theirs.
I don’t think aliens have visited our planet nor do i support the idea that they sowed the seeds of life on earth, but they are certainly out there somewhere in this vast universe, may be we can find(contact) them in the fairly distant future.
I think it is a bit egotistical to think we are the one and only lifeform in the entire universe. Alien lifeforms do not have to have the same intelligence we do. They might be little wormy type things building their own form of colonies. Or maybe the aliens are so egotisitcal they don’t believe any other lifeform could exist and aren’t looking for any. And who is to say they have to be more technologically advanced than us and are able to get to Earth from wherever they are. There is much to be said about observation without detection too.
I think they probably do.
Lol.I guess I mean 6th!
I think aliens do exist. Just they are not here. They have not traveled the spans of space to pick on us and probe us and put tracking/mind control chips in us and all that crap.
Some where out there, there is another planet(s) which supports life. It may not have the exact same qualities of Earth. But just like us, the “people” who live on that planet have a complex system that makes their existance on their planet possible.
The thought that in the infinate span of the universe, we are the only planet that supports life…..
That just doesn’t make sense to me.
With the inpractical limits of the universe, they must exist. But with our limited technology, there is a incredibly tiny possibility of finding them. Thus, for all practical purposes, they do not exist.
I am sure they exist…I mean all those stars and all those planets up there…how can there NOT be some other life form, as for them having visited earth well lets just say I highly doubt it.
I wonder if there will be any listversers that turn out to be UFO nuts? lol
Oh and by the way….
Purdnasty: You read too much Steven King.
Allthough if they did exist are they more advanced then us or not? Maybe were the only ones lucky enough to have advanced so much…or maybe they exist on a different plane of existance all together…
haha not I sound like a nut
I’m not! Honest!
Aleins do exist. The if the universe is infinite then it must be a mathematical impossibility for there NOT to be another planet in the universe that holds another form of life. Just because another planet isn’t like Earth, in terms of temperature and chemical make up doesn’t mean there is not life on those planets, just different from what we have come to expect on Earth. Imagine, for example, a silicon based lifeform living on a planet similar to Mercury in our solar system. Just because we haven’t seen them doesn’t mean they don’t exist.
‘Absense of proof does not mean proof of absense.’
I’m inclined to agree with JF, but at the same time perhaps they follow a perverse “Prime Directive”. Under no circumstances shall any “primitive” civilizations be disturbed. But at the same time we think they’re out there. Which lends credence to the law that states, “By observing an object you change it.” From a religious stand point, I don’t think they exist. From a personal standpoint, it’d be wicked awesome if they did. Until I get to a logical standpoint, They’re more than likely, hostile, poisonous, or otherwise damaging to us. So all in all, I hope and pray that they don’t. But it’s a nice thing to think about.
They do.
I don’t know if they exist. Perhaps they are mere bacteria at this point awaiting evolution. Maybe they mirror our evolution and like us, wondering if we exist. All I can say is that if they do exist, I hope that they are nothing like us due to the members of our society who feel the need to destroy each other, be it from simple murder, to full scale warfare. I think that for that reason there, it is better to not find them at all. We are just too evil.
Maybe the better question to ask in this would be ‘do intelligent aliens (with the ability to explore the galaxy(?))exist?’
somebody who is pro-alien and anti-God chime in and let me know how you can dismiss the latter for “lack of evidence” and champion the former when less evidence exists.
MiamiCane are you a politician?
Of Course they do! I wouldn’t be here if they didn’t. Nor would you! Always have been, and always will! Alien Civilizations Exist! Try UFO Files on History.com, or UFO Association.
If aliens exist, why are they bent on abducting Joe Schmoe from the middle of Nowhere? Why would they take them aboard the ship, experiment, and go through the trouble of covering their tracks while giving the victims life-long problems? They could just as easily break into one of the millions of libraries/bookstores throughout the world and take a books of anatomy. Or physiology. Or psychology. Anything! After all, we’ve been studying ourselves from day one. Who knows more about the workings of the human body and mind than us humans.
Personlly, the thought of aliens has always been ridiculous. They seem to use methods that are not on par with their supposed advancement.
And if they really are abducting people, why are the taking semi to very credible people who will come back and tell the world? Why wouldn’t they take a bum or difter whom no one will miss? They wouldn’t even have to bring them back! I know that sounds terrible (which it is) but it would be much more practical.
Have aliens visited Earth? Very likely not. Do aliens exist? Without a doubt. Why haven’t they tried to contact us? Maybe they have, and we just don’t have the technology to receive their messages. Remember, a signal sent across space needs sending technology and reciprocal receiving technology. Maybe they’ve been trying to contact us for thousands of years, and we just can’t hear them. In any case, there is undoubtedly other life in the universe. There is also undoubtedly at least one other planet in the universe with intelligent life on it, and perhaps many others. Hopefully the human race will survive itself long enough to find out.
With apologies to Dennis Miller:
If any of you aliens out there are reading this, first of all, thanks for visiting the List Universe. Now I want you to listen up, Keldar from Ramula 5. If you do come here and land in a rural area, please stay out of our asses. There’s nothing in our ass that will help you save your dying planet. Life is tough enough out in grow country without you proctonauts dowing a case of Zima and getting your moonrocks off by checking Jethro’s oil.
That depends on how you see the universe. If the universe (or Cosmos if you prefer) is infinite in space and time, then sooner or later there will be life on another planet. Although thats not to say that there is life somewhere else right now. Life may exist on a planet billions of years before or after the earth exists.
Now if you believe that the universe is NOT infinite (at least in regards to time) then I’d say the odds against life existing in the first place are so astronomical that there is no way life could exist somewhere else.
I agree with jf they most certainly do not exist.
Again, Dennis Miller:
Some say an alien craft crash landed outside of Roswell New Mexico. Yeah, because they can travel millions of light years dodging comets and asteroids but those New Mexico telephone wires are a real *****!
bucslim: heh nice point
nope
they most likely exists but we wouldn’t know about it because they would have to be able to travel at light speed, or they would have a telescope that is way stronger then ours on earth, or they are just not as smart as us yet. ethier way, earthlings will never know unless they want us too or we find them first.
There are life on other planets, thats a fact, though its only bacteria that have been found (please note that, DiscHuker, thats already more evidence than there ever was for god). If by aliens you mean life more intelligent than ourselves, that’s a different story, even though it might be possible. I think we could be the most advanced civilization and there are others out there who are developing.
i think people look at this wrong. i do not believe aliens have ever visited earth….or if they have, it happened in the 99.9% of earth’s history in which humans werent running the show.
but somewhere in the seemingly infinite amount of stars in the universe (i once heard that there could be about a billion stars per every grain of sand on earth) there is most likely a good number of planets in which life exists.
even if you did all the math to find out just how unlikely life forming on earth was, lets say it was 1 in 100 trillion, well, theres probably more stars than that, and odds are, more than a few happen to have an earthlike planet around them.
so to reiterate, i do not believe intelligent life has ever visited earth while humans have been in charge, but somewhere out there, even if its a few colonies of bacteria under some rocks, there is life.
to try and deny that, as hank hill would say, “is completely asinine.”
I agree that mathematically speaking there has to be other life out there in the universe. To apply similar logic, they’re probably just as far a long as we are technologically.
to ginger lee:
or further. think about the advances weve made in just teh past decade. now imagine a planet that follows a similar path to earth but developed 1000 years sooner….or a million. what could humanity do with another million years of advancement? (assuming we don’t destroy ourselves along the way)
yes, in order to transcend into the heavens, we must leave worldly posessions behind,… long ago, this was recorded by man, still believed by some, and gives some hope for the future to escape this hell
we are aliens
Just wanted to point out the universe is not infinite.
Scientists have discovered that the universe has a distinct “soccer ball” type shape as a boundary and this boundary is expanding.
Another way to prove space is not infinite is the amount of stars in the sky. If the universe was infinite then the amount of stars would be infinite and the entire night sky would be lit up. Think about a forest that has an infinite number of trees. You could not pick a point and see empty space or see through the forest, you would just see trees. Similarly, if the universe was infinite, you couldn’t see “empty” space or blackness, you would just see stars.
Oh, and aliens do exist.
SlickWilly:
What about the Wow! signal? It was mentioned on a list on here recently…
since i tried starting this debate a few times, i am on the side that aliens do excist
whether they have been here or have the ability to get here i not know nor care :p
I find it very hard to believe that we are the only intelligent species located in the Universe. And who knows if they have visited because if they can make it to earth they sure as hell can keep hidden away from us
Also, if aliens have visited Earth, why hasn’t a government come forth and said so? There are conspiracies that the U.S. government is concealing the truth about extra-terrestrials and UFO’s but our government is just one among hundreds. Surely if the aliens have made contact, they have done so outside the borders of America too. I would imagine at least one government would come forward and say they definitively acknowledge that aliens have been to Earth. It’s tough to think that all the governments in the world are concealing the truth.
I think aliens exist but just haven’t gotten to us yet.
I believe that Earth cannot be the only planet in the Universe able to sustane life. There simply must be other forms of life in the universe, remember that the universe is a VERY big place. The chances are that we are far appart and if there is inteligent life like us, who is to say that they are more or less technologicaly advanced than us, or that they care about other life. Another possibility is that there is life, but it could well just be small strands of bacteria, or insects, or mabe even complex organisms like dogs and cats.
fishing4monkeys: It is much more logical and simple to understand that the Wow signal is most likely not of extraterrestrial origin. There are other theories that have been put forth that explain with a greater degree of efficiency the nature of the Wow signal, other than those that believe it is a legitimate extraterrestrial signal. As for me, I’m a skeptic. Why haven’t we picked this signal up again, in almost 30 years since it was registered? I believe it’s more likely the signal was mistaken identity of a terrestrial-based signal. BUT, I am not an expert on the Wow signal, or the technology associated with the field, so I won’t say there is *no* possibility that it is an extraterrestrial signal, just that it is more likely that it is not.
Tommo: I agree with you. Just because there is life does not nescessarily mean that they have to come to earth. If they are inteligent and could travel to earth, in all honesty, what would there realy be to gain for them? If they have the technology to get here then that means that they are more advanced than us anyway, and there are probably other planets for them to go if they need resources that are not populated by inteligent life.
i hate the stereotype that all aliens are really advanced and fly around in spaceships.for all we know we could be developing faster then other races out there and then we could be the ones coming into contact with them and sharing our technologies
Who are any of us to say? I think all supposed alien encounters we hear about on tv are hoaxes for sure though. I think saying “oh yes aliens definitely exist” or “no way I know for a fact they don’t” is pretty silly. Until someone gives me some extremeley competent proof I’m not going to believe either side of the fence.
Mathematically yes, some sort of life other than ours has to exist, but that does not necessarily mean it’s what we might deem ‘intelligent’, if it was we’d have had so-called contact.
And yes, I agree with the disease theory. All biologically rather risky. In short, yes, but not the kind of alien life most people think of I would say. I’m thinking single celled organisms or some sort of un-intellectual life somewhere… but personally chances of that I think are slim… but the idea is cool.
Its obvious that aliens exist.. mathematically.
But i read that the chances that two life forms from different planets ever meet in their lifetime is extreemly thin… practically impossible.
Humanity has never and will never meet a life form from another planet.
Yes they exist and no they haven’t visited because they don’t care. Waste of time.
This is straight from a Calvin and Hobbes strip. There are two possibilities: either aliens don’t exist and therefore we have made no contact, or aliens do exist, and because they are intelligent and have advanced technology, they know not to interact with humans.
Another thought- if aliens do exist, why exactly do they have to have flying saucers and more advanced technology than ours? What if one day humans have the technologies that we believe aliens to have and we in fact become the “little green man” to a species on another planet?
I believe aliens exist, but also that we will most probably not come into contact with them, at least not in the lifetime of anyone posting on this board. But the existence of aliens would be awesome!
P.S.: Jfrater, I love the way you poke at Scientology. Especially on the boards where you come out and say that Scientology is a blatant lie. It’s always funny, but also very informative. Thanks for keeping this site great!
yes!
tommo – even if there was an infinite number of stars the light of most would not reach us because they are too far away.
all you math nerds – explain how aliens exist mathmatically???
seriously, just because the there is only a one in a trillion chance….hello! earth = one. we win. we are it.
I think it is highly likely that aliens exist. I also think (hope) theyre smart enough to stay the hell away (someone here already mentioned how disease destroyed a civilization, but think of what one of us (probably “we”) would do on purpose!).
Should we have a UFO cult (read: “Scientology”)? No. And we shouldn’t go looking for them, either. The consequences are such that we cannot afford.
Either they’re malevolent, or we’re going to do something stupid.
if there are aliens out there, they are probable in some other galaxy and we will never know. so its a moot point to argue this stupid question. Please, new list jfrater, something we can logical debate and back our arguments with real evidence.
I think they really could exist, though why would they be smater, for all means isn’t an alien not just a living organism on an other planet. who says there even big enough to see with our eyes, or that they have a somewhat same social structure.
in they question would there be aliens just like in movies and such no, but otherwise, I do think there other living organisms on other planets adapted to that special environment.
I was pretty excited to write a response to this…and then I read the first few and realized that someone wrote down exactly what I was thinking, especially the egotistical bit (except it was worded much better!)
I agree with you whole-heartedly JwJw!!
I have no doubts aliens exist. Whether or not there are aliens that can reach, or are capable of reaching, us yet is another matter.
The universe is (for the sake of this argument) almost infinite. I refuse to believe that there aren’t planet with the right conditions for life.
