Yes, we have had plenty of threads of which have been titled to the lines of 'Do Aliens Exist', or 'Do UFO's Exist', or 'Do You Believe In Aliens', this one however, I hope to be slightly different. Usually, when people refer to 'Aliens' they mean little Green men, from another planet, who have landed a Cigar / Saucer shaped ship somewhere.. Why we never see anything to the like of Star Destroyers, or Galaxy Class Starships I'll never know. Anyway... What I would like to talk about goes beyond that. Was having a 'debate' with a fellow colleague at work the other day, a debate of which got really frustrating, for the simple fact that he wouldn't keep his mind open to possibilities. Anyway, anyone who has the slightest knowledge of Space, will know that the Universe is huge, and that Earth, and all the other planets within the Universe have been around for billions of years. I say this with the assumption that the average forum user isn't on the same belief level as Jeff & Eddie. Anyway, lets start off with our Solar System. A total of eight planets (they've discounted Pluto), all orbiting our Sun. From there, we know that our Sun is orbiting a supposed mass, at the centre of our Galaxy. Note, Galaxy and Universe are not the same thing. Along with out Sun, there are many more that also orbit the centre of our Galaxy. It would be a reasonable assumption, that many of these other Suns, also have planets orbiting them, just as ours does. Then you'd compress our Galaxy, and all its belongings. You would then look at things on a larger scale. Out Galaxy is one of billions, orbiting, or floating (whatever you'd like to believe) the Universe. This ultimately gives up billions, upon billions, upon billions of planets, throughout a vast area. Obviously we have no idea how big the Universe is, but we know it is BIG. Now, to think that Earth, is the only planet in the entire universe, to actually have life on it, to me, is mad. However got here, be it define intervention from a being of great power, or some alien race planting our seed, or by some cosmic event that happened to our planet, after it was hit by an asteroid or something, the fact is, somehow, we've managed to get this far. To think we're alone, to me, just doesn't make sense. When we think of all the other planets and possibilities that are out there, to even think that one planet alone, is the only one that is essentially different to all the others (because it has life on it) would make me wonder what is next for us, when we do reach the stars. I wouldn't really go into whether Aliens have visited Earth or not yet.. I really don't know. Plenty of people have said they've seen Aliens, yet there is no proof of them. The thing is though, is that if there was life on other planets, considering how vast space is, would they even know about us? Would they even know about Earth, or would they be so wound up in their own lives, that Earth would be 'just another planet' to them?

I see no reason for it to be impossible. After all only a few planets have been studied to be fair I would have to see them all, and know a fair amount about each planet and every existing life forms. Life forms may already exist as we do not know it, understand. Perhaps even right under our noses. To ponder if there is life on other planets is a bit pre-mature . To say that there is no life on other planets without knowing a specific alien life form, and its specific needs for life on another planet, as well as resources that we are clueless to is basically silly. We do not know the planets , most of them, as well as alien life at all. So who can say what alien life is , what it needs , and how it exists. All these things are beyond atleast the common man , but perhaps not the scientist .

Alien life does exist, but not as we know it. Bio orgasms was found in water on I think it is mars . So alien life has been found by scientist even under publication that has been own. Simply people did not realize it , because they are thinking of big green men or something or rather.

We have cliches in our mind of what aliens are from books, tv, movies. Then again alot of science is alien to you all. Life is of science . Some life forms not even alien, you are clueless about, as well as where they live, need to live because you know nothing about them.

So it is possible, I see no reason why its impossible because so much has yet been unexplored for such a hasty generalization for it not to be possible.

We know too little to assume.

Alien is someone who gets on my property...no that is trespasser sorry.

Now what you say is seemingly correct. There is no other way that in place this big humans are the only living organisms. To add something to the topic I am not sure where I heared about organisms in the marse's polar caps... What my opinion is that humans had a freaking luck during evolution let's say 100000000000000 of one perhaps and are as they are. The other planets organisms might not have been that lucky. There are many factors that influence the way of development so if there are another intelligent life forms in the space they must have been pretty lucky.

The other thing is my theory I made when I was 9. We say that organisms are living beings based on carbon. But what if there isn't really anything that doesn't live? For example: What if a rock is an organism not based on carbon? But it moves lot more slowly, a LOT more slowly than us and we just can't realize it? Well I made this theory when I was young so I do not put much relevance to it...

Yes, when observing another life form, it could simply be in a form that we are alien to , but that does not mean that it is alien to a life science. Our definition of a life form is earth bound, and not even a 100th of the universe.

There is alot out there . I see no reason its impossible, but given evolution as we know it , it can seem unlikely. What else is out there in the universe though, perhaps some place else "luck" is not as much needed.

What is an alien life form in whatever case, and what does it truly need to survive, live , evolve. The universe is old ...who knows what is out there.

I was reading a supermarket magazine and it said that cats on Mars had destroyed the rover there.

There's your proof.

Currently is? No. Has been? Possibly.

I believe that while humanity was still hunting with rocks, there might have been a civilization somewhere in our galaxy. Heck, they might even have visited Earth a couple of times to check out how life progresses. Over time, their planet would break down as Earth is slowly doing(That discovery channel program "100 Years Post Humanity" creeped me out...) and they either died with the planet, or they fled the galaxy. We might also just be VERY unlucky to be one of 5 bizillion galaxies to be uninhabited. Who knows? Maybe they're developing a galaxy destroyer somewhere 5 galaxies away, plotting to rule their galaxy, unknowing of our existence?

There is definitely life out there in some form. To say that we are alone in this universe, or even in this galaxy, is very narrow minded.

I do think it is very easy for life to get started (although complex life is a much more difficult achievement, if our planet is any indication). I even think that once life starts, intelligence is inevitable (it's just so damn advantageous, evolutionarily speaking). This subject is something the human brain finds very difficult to comprehend as when one question is answered, another arises. If life, or rather intelligent life, exists outside our solar system, where is it? I really doubt we are the first in the galaxy, and it is likely technological civilisations existed in the 15 billion years before us. So where are they? Perhaps, they just could not travel far beyond their star system--they could not get past the light barrier. I am aware that "absence of evidence is not evidence of absence," but still, it is not a bad supposition. The absence of space fairing civilisations is a good indication that something in that process is very unlikely. Which leaves several different scenarios; 1) We are indeed the only life capable of technology, self-awareness, etcetera in the universe (in which case, life is extremely precious). In my opinion, I believe the likelihood of this scenario being correct is next to zero. 2) We are not alone, but under some high tech "quarantine" which is preventing any communication efforts. Heh. 3) The universe has just reached the age of "intelligence evolving", that is, we are one of many other life forms who are just now branching out - we just haven't found each other yet. There are no older intelligences out there. In other words, maybe all life evolves at the same rate. 4) Intelligence capable of some "warp" travel is very rare, and so spread out that even with such travel, it's unlikely for them to find each other. 5) Maybe there's multitudes of intelligent life out there, but few who have a drive to explore, or have some built in paranoia against finding other life so not only do not look, but hide any sign of them existing. But if we don't find a way around the light barrier, like through space folding or some other "shortcut" method, and assuming we manage to survive ourselves and branch out into space to live permanently, then we'll begin a slow crawl towards the stars pushed by resource needs. Although, saying that, there are several speculative mathematical models regarding 'warp drive' - for one, the Alcubierre theory, so it is being/has been studied thoroughly. A lot of my reasoning also comes from the Fermi Paradox.

Additionally, if there is life out there, I don't believe they have to have the same traits as humans. For example, I don't believe all life is carbon-based.

Well, theres also that theory about how Humans is a new specie, and therefore is protected against the other species. Would make sense. I mean, right now, if aliens landed in times square, what would we do? Nuke New York. If a ship appeared in our atmosphere? Nuke the atmosphere. If it appeared in the water? Nuke the water! We would destroy it because we're a bunch of agressive apes :D

There would be a sense of world panic. I don't honestly think we'd be prepared for an event of that kind - we wouldn't really know what to do.
