do extraterrestrial beings exist out there in space? are  some of us aliens?

Life exists almost everywhere on earth, and it has many forms.  Some of which are almost impossible to detect and it's debated whether they're actually "life" (like virii).\n\nIf it could be proven either way, I would bet my worldly posessions and my right arm that there is some sort of life beyond Earth.  They might not be carbon-based or water-based, but I am certain that there are objects out there that consume things, grow, reproduce, and possibly defend themselves or even have rational consciousness.\n\nAs for some alien being looking just like a human and living among us, that's a different story.  I can't see two independent strains of life coming out so similar, especially considering the variety right here on our little planet.  Either we'd all be from alien roots, or the "aliens" would have originated from earthly roots.

No.\n\nSo far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.\n\nWhy haven't we heard from them?\n\nPerhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.\n\nPerhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that flew by may be a surveillance craft.\n\nPerhaps they are so far away they will never notice us and vice versa.\n\nPerhaps they existed a million years ago and died out.\n\nPerhaps they will exist a million years from now.\n\nIt is really impossible to know for sure.\n\nThe Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

Like they said in the movie Contact, I don't know, but if not that's an awful waste of space.\n\nYes, I believe that life exists in some form out there. I'm not sure if I believe they are "among us" but I do believe we have a lot of unanswered questions regarding UFOs. \n\nThe government hiding things from us? Awwww. You don't think they would really do that, do you? You'd be amazed at how much our government keeps from us. I worked in military intelligence at one time. There is something called "a need to know." And who do you think decides who needs to know?

Great philosophical question.  I believe there are other living things somewhere in space.  Even if you believe we are a random happening, there are so many millions of planets out there that there would have to be a second occurrence like what happened to us.  And if there is a god, then I am sure other civilizations were created as well.  So either way, there is a good chance there are other life's somewhere in space.

Well..not speaking for anyone but myself...Yes UFOs are real..I have seen them all my life..I dont mean lights in the sky but true objects that have incredible speed that would make the latest military rockets seem like horse and buggy, speed that is instant....manuvers we cannot do..I have seen these objects day time and night..more frequently now then ever before in my life. I have never seen an alien..nor do I want to. The stories told abductees, does not seem very pleasant.\nWe ...are very young.. and very UNintelligent..we dont even know what the universe is made up of..We have a long way to go before we can claim we are the intelligent beings we say we truly are. \nYes they are real...and not from here.

Are Humanoid aliens real?  Are Silicon-based aliens real? Are Methane-based aliens real?\n\nIn science fiction, anything is possible.  In real life, we have not encountered these beings yet.\n\nReptillian aliens are possible, but I would assume that alien beings evolved in different ways that life on earth, so there might or might not be any remote similarities......

there hasn't been any found yet.... but... the possibility of life on other planets is very  high....  :)

Aliens can exist. We know very little about the universe, but aliens in Area 51... I don't think so.

The problem is, that's all most people think aliens are; little green men who ride in weird-looking UFOs. Aliens, in the true sense, would be any form of life anywhere outside Earth. Now, in a universe filled with millions of galaxies, each galaxy with trillions of stars, and each star with at least 3 planets, what do you suppose are the chances that only ONE planet had the right conditions for life? Now, as for why they haven't come to Earth, ask why we haven't gone to them. We're always under the impression that aliens would be super-advanced and omnipotent, but why would they be if we're not? For all we know, we could be the OLDEST form of sentient life in the universe. And if not, and there are alines looking for life and listening for radio signals, if we sent a radio message to the nearest (possible) habitable star system, it would be hundreds of years before it got there. And who's to say they'd even be looking in our direction? To dispute the existence of alien life just because it hasn't made contact would be like saying cells don't exist because you can't see them without a microscope.

Of course I think life exists!  Infact, I beleive there is life in the solar system.  How do we know if there isnt life floating in the clouds of a gas giant, or icy crystal like things on pluito?  We havent searched hard enough for these yet!  Duh!\n\nLife outside of the solar system might be a little hard, considering that there are only "hold jupiturs," and "frozen earths."  Both are to hot or cold to support life, and they are massive and have insane gravity.  However certain single celled organisms, say bacteria or such, might reside on the planet.  I always thought that might be.\n\nIn addition, Europa, a moon of Jupitur, has ice flows on it that scientists think liquid water might reside under!  It might be interesting to see what could live there.  From the means of life there, I came up with a skating green creature who could move around on the ice, absorb the moisutre of the water, and undergo photosynthesis to obtain energy.  \n\nEnjoy!\n\nNote: I do beleive in aliens, but dont beleive in UFOs.  Considering how many hot jupiturs there are, I dont think we will even see any life as smart as we were as cavemen until alot later in time...

Out of 10,000 Billion Galaxies out there. No Doubt there is something out there.\n\nEarth will contact something...but not in our lifetimes.\nI even believe there is another planet like ours out there somewhere.\n\nWe would be very naive to think we are the only intelligent planet in the entire Universe.

Absolutely! The odds that they exist are overwhelming when you think of how GALAXIES are scattered like specks of dust!\nNow... even though aliens exist, what are the odds that they are on another planet in our galaxy right NOW? Think about it... It took 50 million years for humans to appear on Earth. How long will we be here?... only 50 to 100 thousand years (hopefully)? How many other planets will bring forth intelligent life - not a whole heck of a lot. And of them, when will that life be around? Just a tiny amount of relative time.\n...What I am saying is that EVEN IF other civilizations were, are, or will be... the timeline of the universe is too insanely long for any of us to be co-existing. The reality may very well be that we are currently very alone here in our time and place. I hope this gives you a new, more realistic way of seeing things. Sorry it's such a downer, though!

I feel some clarification is in order. ANYTHING that you see in the sky that you are unable to identify is by definition a U.F.O. Calling something a UFO doesn't automatically make it an extraterrestrial spacecraft full of little green men. I have seen plenty of things in the night sky which I could not identify, so yes I have seen many UFOs but I don't think I've ever seen evidence of extraterrestrials.

i do because there are many galaxies are there. but you just wait because in the next 20 years we'll  be able to detect alien life forms other than our planet because if there are those aliens are trying to contact with us by waves (like we use on our planets for example, radio waves.) there is evidence that life used to exist on mars. not like life like us (like mircoscopic things). there are many stories that aliens have come to visit our planet. can be true because as they are as they are described in the movies all these phonomenons are happening buts its not possible for us yet to go visit another galaxy. not eveough human years. but in the next upcoming years we'l have ships that will be able to jump into time. as we are doing right now for example, when a space shuttle stays in orbit for atleast a year, they jump into time by 3.8 seconds. its hard to believe but its true . in star trek when they jump into time there using those worm holes. they exist but there so damn small that we have to enlarge them. there smaller than an atom. as phsyics desribres its not possible to go as fast as the speed of light it'll be possible in the next upcoming years. (i dont no when though) but if we go any faaster than the speed of light we'll be crushed by the gravity so that is why we'll be using worm holes and that is one way that we'll be able to visit other galaxies. i hope i stay alive doing that time lol

Aliens from outer space.

Yes, I fully believe there is life on other planets.  What it took to create life on Earth was not favored to happen.  The odds that Earth would hold any life at all are too small to comprehend.  But we do not know how large the universe is.  We do know that there are trillions of planets, trillions of galaxies, trillions of stars.  The odds that there is not a speck of life on any of those planets is also extremely small.\n\nI must admit that I have seen a UFO, which occurred last year.  I was driving my friends home from a party and I happen to look in the sky to see a bright white diamond-shaped object.  There were four individual diamond lights that made up the overall shape.  I was astounded, and I knew it was not anything that the United States had admitted to having.  I could name every military jet, helicopter, blimp, and passanger aircraft that I see, but I could not for the life of me figure out what it was.  I immediately turned around and drove to follow it.  Within five-ten seconds, the craft had flown so fast that the lights had disappeared (I watched it the entire time).  I'm not saying it was extra-terrestrial, but it was a UFO.  I live in Cleveland, by the way.

If you are referring to other planets that are habitable, I believe that mathematically there has to be intelligent life in other parts of the universe. Here is why.\n\n1. The Hubble Telescope estimates that there are 125 billion galaxies.\n2. Each galaxy has roughly 100 billon stars.\n3. If even 1% of those have planets and only 1% of those are habitable and only 1% of those have life, the odds are high.\n\nThe odds are extremely favorable for there to be extraterrestrial life. \n\nOne can use Drake's equation to calculate the chance of life in our galaxy. Multiply that result times the number of galaxies. See the second link below.\n\nA totally different question would be whether or not we would actually interact with extraterrestrials...\n\nI will leave that one to another Y! Answers Question
