Aliens exists.

No ifs or buts about it.

Because the universe is so large; even life exits in our own galaxy.

Life can be any thing that uses an energy source and actively reproduces itself, to make more.

The skeptics may be not be aware that, humans are a dangerous species.

Just look at the health of the planet, we are always at war and we consume and destroy anything that we think is useful to us. .

For this reason advanced alien societies have concealed them selves from the human race. One day we will find these societies, at a time we will least expect, in the near future(100-500years).

Aliens today are just observing and investigating the potential of our species, just you wait.
In the near future, we will be intergrated into one of these alien's society.

You can not dismiss this, "think out side the box".

First of all, correct the thread title : Alians, they exist? lol

I read somewhere that aliens have been visiting the earth because we are disturbing something something spacetime continuum with our atomic bombs. Yes yes very confusing. Anyway, too bad none of us are going to be here in 100-500 years right?

You know by then people will also exist in electric cities, where their boy has died but their mind still exist, but on a computer as an HI (Human Intelligance).

I believe Aliens do not Exist.

However, UFO's exists, but are created by humans.

Yes, other life forms do exist, can I show you prof, No. Mathimaticaly i can show you anything.

As far as believing,well yup i do. As far as saying i have eviedience,nope.

But that just opens a whole can of worms, I find it better to sit back and watch.

Only time will tell, and the freedom of information act, well thats a load of bull.

You may think i'm talkin out my ass, but hehe wait.

I find it hard to believe that there isn't another form of Alien life out there when there are millions of galaxies in the universe. It could be very possible that we are the only life in our galaxy, but to automatically rule out existence in the rest of the universe is ignorant.

Whether or not there are aliens that are smart enough to travel to Earth in UFO's is another thing. I DO believe that there are other entities in the universe smarter than humans just because in all of these years no one has been able to land a man on Mars.

But hey what do I know. It's just what I believe so skeptics you can say whatever you want.

I know this is off topic, but Calgary Flames and Jerome Iginla suck.

Its all fun to imagine aliens and what they look like. But until the day i see one, or travel to space myself, all opinions and theories are just that, theories.

I wouldnt rule it out... but its implausiable for my spiritual self to concieve.

heh.

Even if there are aliens, whose to say theyve visited earth?

I mean, just to say there arnt aliens because they havnt come here would be as egotistical as saying there arnt any at all.

Think about it this way: suddenly a great advance in science makes faster than light travel possible (the hyperspace engine, perhaps?). Where do we even begin? If youve ever been in a very dark area, one without a lot of light around, such as maine, or other areas far away from cities, and even suburbs, and you look up at the sky, you know how many stars there are. These are only stars you can see. In our own milky way galaxy for the most part. Think, these are all stars, as our sun is only one star. Now, do you really think that out of all those stars out there, that ours is the only one with a little planet earth out there? I really doubt it.

No one knows. Well some people may know, but we will never know the truth. Not anytime soon anyways.

As this thread ia about "Extraterrestrial Life & The UFO Phenomenon", I'm moving it to the Extraterrestrial Life & The UFO Phenomenon forum.

Eeeeeeek! This looks like alot Ghost in the Shell!

lets say, you see a huge house, just because it's so huge and it COULD, the keyword is COULD have alot of people in it, it don't mean there's people in it, now does it?

Thanks

No one on Earth knows the prerequisites of live, therefore it's impossible to determine if there is alien life using probability alone.

Life probably exists...The question is, are they intelligent? It is much, MUCH more likely for simple life to exist.

that's your opinion... can you prove it?

Right, but where there is any form of life, it will evolve; unless of course it can't reproduce.

Evolution takes Hundreds of Millions of years

Considering the age of the universe, I'd say the odds are still that intelligent life exists...
To even think that earth has the first and most intelligent life is absurd... We are merely humans... To base the whole of existance on us is pretty crazy IMO...

You have a point here,we still cant say what real aliens are like, of course, but science can provide some useful insights. After all, if there is any biology out there it will exist in a landscape of finite resources. Darwinian competition will be their lot, as well as ours. So you can expect that there will be predators. Predation is an economic device: carnivores leave it to plants or plant eaters to slowly build up energy-rich molecules from sunlight or some other source. They then harvest this crop of useful compounds quickly, a tactic that can power an active life style.


I agree with MF on this, but untill there is undisputed evidence this is pure speculation.

DELETE ME

there is only evidence for HUMANS... anything else is merely speculation...

Don't be too sure...

And assuming that the average estimated age of the Universe today is correct, any life that has existed/does exist, has had hundreds of millions of years to evolve.

exactly

We don’t know much about the average lifetime of technological societies, other than the fact that ours has, so far, managed to survive for a century. We also don’t know at what rate sentient societies spring up in the Galaxy. But we do know that this rate is surely tied to the frequency with which stars are born. Clearly, a greater flux of new stars will ultimately produce a larger number of planets with thinking beings.

What is the star formation rate? Well, there are roughly 200 billion stars in the Milky Way, and that means that the average rate over the last 13 billion years has been about 15 new stars per year. In fact, however, this average rate is two tads misleading. Anyone who’s used a radio telescope to study galaxies knows that when you examine a big spiral like the Milky Way, you find that the total amount of interstellar gas is typically a few percent of the mass of all the stars. Since interstellar gas is the stuff from which stars are built, it’s obvious that there’s little material around today for constructing new ones.

Sure, stars explode as they die, spewing some of their contents back into space. Even the Sun will blow off some steam as it heads for the stellar bone yard. But the great majority of what’s inside the Sun will stay there forever, locked in by gravitation. The ingredients for new stars are sparse, and most of the stars that our Galaxy will ever make… have been made.

Mary Barsony, a Research Scientist with the Space Science Institute, notes "these days, the stellar birth rate in the Milky Way is only about one solar mass per year. The Galaxy’s not nearly as fertile as it once was. It seems that there was a real burst of star formation more than 10 billion years ago, though. Those early years were when the stellar population boomed."

In other words, our Sol is a real sunny-come-lately.

Clearly, this must affect the roster for our club of intelligent beings. But how? There are two obvious possibilities. One is that intelligence is such a useful attribute that technological societies last a really long time – billions of years. Heck, trilobites lasted a half-billion years, and they weren’t even smart (by any reasonable standard). So maybe the thinking-beings club is home to really, really old societies, and we’re like preschoolers surrounded by grad students.

The other possibility is that, no, technology doesn’t survive for such long time spans. And while the Galaxy may have spawned great civilizations in the deep and distant past, they are mostly gone now. In this scenario, other club members are not quite so ancient, but they’re in short supply.

We know of only one world with life, Earth and so all we can do is speculate, with little evidence, but here goes.

The Earth is believed to be about 4.55 billion years old. We know that life started on Earth very early on. In fact it seems to have started almost as soon as the "'late heavy bombardment" period of meteorite activity finished some 3.8 - 3.9 billion years ago. So life got going almost at the earliest possible moment. From this we can speculate that where the conditions are correct life forms easily.

It took until about 1.8 billion years ago for the first cells with nuclei (Eukaryotic cells) to appear. The first multi-cellular life did not appear until about 544 million years ago. This means that multi-cellular life has been in existence for only around 15% of the time that life on Earth has existed. From this we can speculate that although life forms easily, multicellular life if far more difficult. It is quite possible (even probable) that most planets where life forms it will never progress beyond simple bacteria .

However once multi-cellular life had evolved evolution accelerated. The Paleozoic Era, between 540 - 245 million years ago, starts with simple animals but ends with complex fish, amphibians and reptiles. From this we can speculate that if multi-cellular life forms the chances are very good that complex life will follow.

So where does that leave us for intelligence? We need some definition of intelligence here. For this case we can define it as being able to produce technology (a narrow definition maybe, but if they don't meet this criteria we are unlikely to be able to communicate with them).

Complex life has existed on earth for more than 200 million years. In that time the most advanced phylum, chordata, has produced countless thousands, maybe millions of species. And yet only one, man, has ever evolved the kind of intelligence necessary for technology and that has happened only in the last million years. That is 0.5% of the time that complex life has existed and 0.000000025% of the time that life has existed on earth.

So our suppositions can be summed up thus:

• Life forms easily.
• Complex life does not form easily.
• If complex life does form then evolution will become rapid leading to a wide variety of life forms.
• Even with the huge variety of life that is possible, intelligence is rare.

Fortunately the universe is big. Even if intelligence is rare there is a fairly good chance that it has evolved somewhere out there. Whether that is close enough to us that we will be able to communicate, who knows?

Of course all my conclusions are based on just one case study, earth. The reality is that the universe my be teaming with intelligence or we may be unique. I find either option equally amazing.

very good post!!!

and can u also prove it that life doesnt exist somewhere out there?... ..

The fallacy of appealing to lack of proof of the negative is a type of logical fallacy of the following form:

"This exists because there is no proof that it does not exist."

Non-fallacious ways to prove something include the use of logical syllogisms and/or the incorporation of empirical observations.

Negative proof

Thank you, Pax Unum, good link. Here's another good one, dealing with burden of proof.

If we are to assume that something exists, simply because one can't prove it doesn't exist, imagine what we could come up with... I have an invisible purple pooka living in my garage. This must be true because noone can prove that I don't have an invisible purple pooka living in my garage!

weak analogy, for real

I think they exist, and it's sooo stupid to think they don't.. If we're here in this HUGE HUGE universe and I really mean HUGE!! it would be really a great mystery if life only spawned here on Earth ONLY, not to mention that considering how big the universe is it wouldn't make any sense.

I dont know for sure if they do or dont, not ever having met one ---- but i do remember about 8 years ago watching a documentary. An American physicist had done a calculus of some sort. I cant remember the exact details but im sure someone does in this forum so please do correct my figures. it went something like this:
if only 1% of stars in the universe have planets around them, and only 1% of those planets have some sort of life form, it would mean millions of worlds would have life of some sort. That formula is considered today to be rather conservative. So what now? what sort of life forms? very basic or very advanced? a bit of each i reckon, But lets be honest --- if we observed a planet where the most intelligent beings systematically wiped out lesser life forms like say, do do's, whales etc --- and systematically walked around blowing up other life forms with explosive strapped to their bodies, and wiped out whole cities with huge bombs, and destroyed their own planet for the sake of making a buck, and for their own lust, violently took the feminine life form by force, and abused the small young life forms etc etc etc would you want to contact them? Hell, i would be out of there like a Long dog.

If aliens don't exist who's going to prove that my statement ant the start is incorrect.
Just for reference how big is space, how big is our galaxy, infact there are more stars than there are grains of sand in our galaxy. So to say life doesn't exist is absurd. Intelligent life doesn't need to be in the space age with UFO, they could be like what we were in the copper age or the stone age, thats still intelligent life.

good point. this is a world filled with terribly aggressive and violent creatures. just as we view the dinosaurs, aggresive and dangerous, and not too bright lol perhaps there are others that view us the way we view the ol' dinosaurs.

Correct we are quite dangerous and humans are only still very young. We need more time to develop into non destructive species, but thats only if we don't kill our selves before this

well i personally think it is pretty selfish to think that even after scientific knowledge of of the earth being far many years older then the bible, that we are still the only Intelligent race in existence. I mean come on........be realistic it wouldn't kill you to question the bible every now and then. Apparentlt many believe that the bible was not inteded to be read word for word in order to follow, but rather study its meaning and then follow.

What i mean by this is in the first chapters in the old testament it speaks of a Noah and a civilization that apparently forget the belief and respect for God. As most of you know who study religion, the entire civilization was destroyed except Noah. However, what makes you believe this was the only occasion something like this happened throughout the history of mankind? The Bible is said to be a guide for your faith, not the history of every single account that happened on earth. Cuz where the hell are dinosaurs then? It doesn't exist in the bible cuz it has nothing to do with faith.

Check out this link, but be skeptical about it: Religous abductee documentation

Geez, I was going to bash this post good. Reading it again, I am not sure I understand it.

The dinosaurs were wiped out by a meteor? Why bring religion into this? What is your connection to the thread supposed to be? How does this relate to Aliens existing?

In short - what is your point???

note i do NOT believe this but its just abstact thinking(what i do when i bored)


i have no doubts in my mind alien life forms exist, of course i cant prove it...but i thin they do.


now some people think the governments know that aliens have been visiting us for awhile, we found that sun thats almost a twin of our sun....think NASA could be setting the world up for a major/shocking announcement?


ps. as i stated above this is just out of the box thinking on my part like Pax Unum sig says

just because theres no proof dosent mean it dosent exist(i know believers have the burden of proof) and just because people say chances are low for intelligent life to exist, but just think..theres billions of stars and twice as many planets....as long as theres a chance no matter how low theres always possibility

Life intelligent and not must exist on other planets. There are just far too many places for it to originate. To say it definitly does not is illogical and arrogant, and (dare I say it) close minded.
Knowing the age of earth in relation to the Universe would give us a rough idea on calculating how much life theoretically might exist. Not sure if we will ever see it, Man might not make it around the next corner, we will have to see.

Yes, I agree with you. Our universe is just too vast to say there is only ONE planet with sustained life... it just doesn't make any sense. Uhh but one correction, no one really knows if any alien races visited Earth. That is still a mystery. But for sure, I do know that many planets in the universe probably sustains life, like Earth.

Sky---Yes, aliens do exist and most people are unaware that the Air Force has already acknowledged the existence of exterrestrial beings in our neighborhood.

The Air Force acknowledgement was contained in its 1948, EOTS report, ATIC, Wright-Patterson AFB, OH. In that report it said, that some "flying saucers" were "interplanetary spaceships, and that was in the Air Force's own words. In 1952, the Air Force reaffirmed ET reality in its Intelligence Report on UFO maneuvers.

And, most people are unaware of the U.S. Army's "Interplanetary Phenomenon Unit," which the U.S. Army has acknowledged and the mission of that unit was for the recovery of downed UFOs. Project Moon Dust and Operation Blue Fly were used to facilitate the Interplanetary Phenomenon Unit's mission. Eventually, that unit's mission was turned over to the U.S. Air Force.

This reply actually has nothing to do with if I beleive in aliens or not.
I just like the topic title AlIANS, they exist
makes me feel warm and fuzzy knowing us beleivers (in anything) can mess up once and a while and show ourselves where we actually all stand. Belief! not Fact! trust me that's a beleif.

A good explanation was in the movie mothman i know its only fiction but he asks why they dont show them selfs and the reply is that we would not understand it would be like a human trying to explain itself to a beetle..
also my theory is similar, if you were walking down the street and a couple of rabid dogs were fighting would you go over and try stop them and show them how to be civilised

hey nirwana in your pic is the pope making some kinda sign with his hands or just a snap photo

first of all, I've only read the first post, and I will only reply to that...
I don't know if the convo have taken another turn or whatever...

yes, aliens do exist, however, I do not believe it's in the form of little grey men probing our asses, but as you put it yourself, the universe is so vast, that it would be stupid and unlogical to think that aliens didn't exist..

You and I are free to believe anything we want of course, but the bottom line is this, there still is no proof of life anywere. As far as scientific evidence is concerned we could be the only planet in the universe that has biology. A dead universe! That is almost as mindblowing as the thought of a universe full of life.

Alians, they exist

Because the universe is so large; even life exits in our own galaxy.
