It was a hoax, sorry.  Also, it was called "Alien Autopsy" and was very popular on the internet a few years back.  The X-Files even did 2 shows about it.  \n\nPictures\nhttp://images.search.yahoo.com/search/images?p=alien%20autopsy%20video&fr=yfp-t-501&toggle=1&ei=UTF-8&fr2=tab-web\n\nVideo's\nhttp://www.trudang.com/autopsy.html\n\n(download small video file - play on RealPlayer)\nhttp://www.legerdemains.com/ac07002.html \n\nhttp://en.wikipedia.org/wiki/Alien_autopsy\n\nYou can also probably look this up under Yahoo! and eBay under the search word, "Alien Autopsy."\n\nRealPlayers (to download to play the Video)\nhttp://www.real.com/

taking into consideration the size of the universe, i believe earth is just a tiny speck on the universe. to think that we are alone would be an ignorant statement, i dont believe in aliens in flying saucers, but other life forms and organisms living their lives as we are, maybe not the same lifestyle but still living

The question is twofold and most responders missed that. To my knowledge there is no scientific evidence of aliens visiting earth space.\n\nBut there is plenty of independent scientific evidence of UFOs. The UFO phenonena has been studied at great length and there is evidence that something comes and goes and that that something operates intellegently.  But we do not know what they are.  \n\nMy personal opinion is that there is likely life somewhere in the vastness of the cosmos.  But I can not believe that life visits earth regularly each and every day all over the globe. So the UFOs may or may not be alien.  But highly unlikely.

We don't know yet, however, I pretty much believe that there are aliens out there.\n\nThere are at least 7*10^22 or 70000000000000000000000 stars out there and it wouldn't make sense that only one of them provide a hostile planet.\n\nThere have been some evidence:\n\n1. Unexplained UFOs\n2. UFOs sightings on the Moon\n3. Pyramids and faces of humans on Mars.\n\nThis not only tell us that there are most likely aliens, but that they're not only visiting Earth, but the Moon and Mars too have been visited by aliens.  My guess is that they receive our signal and is much more advance than we are, so they visit our Solar System and found that the signal came near the inner planet section, and then they came across the Moon and the Earth.  They studied about humans and went on Mars to try to find Martians as well as to tell the Martian that there's people on Earth.  However, they didn't find any aliens on Mars.\n\nAlso it is calculated to be 1 billion planets with life on them in this universe.

The short answer is: \n- - - - - - - - - - - \n\nYes I think it is fairly likely that there is life someplace outside our solar system. I have written a short historical survey, and then summarized some of the reasons behind my answer. They boil down to 2 points:\n\n1. The universe is a big place\n2. Life seems to be pretty common here on earth and start pretty easily. \n\nThe Long answer:\n- - - - - - - - - - - \n\nA. History\n- - - - - - - \n\nThis is a question that people have asked for a long time. The Greek philospher Epicurius (341–270 B.C) speculated that there were an infinite number of other planets like earth, with life on them, in the universe:\n\n“There are infinite worlds both like and unlike this world of ours...We must believe that in all worlds there are living creatures and planets and other things we see in this world.” Epicurius (c. 300 B.C)\n\nThe Dominican Monk and philospher Giodarno Bruno conjected in his 1584 work, "On the Infinite Universe and Worlds", that there were an infinite number of other worlds with intelligent life on them. He refused to recant this and other controversial beliefs, and was burned at the stake during the Inquisition for this. \n\nThe famous physicist Enrico Fermi formulated the Fermi Paradox (sometimes known as the Fermi Principle by skeptics), which states that if advanced intelligent life was widespread in the universe, we would have evidence of it already. Since we do not have good evidence, where are they? \n\nThis was later addressed by Frank Drake with his Drake equation (aka the Sagan equation or the Green Bank equation) for trying to estimate the probability of using coming in contact with an advanced extraterrestrial civilization. \n\nBoth a modification of the Drake Equation and the analyses associated with the Fermi Paradox can be used to try to estimate the likelihood of there being life beyond our solar system (the interested reader is directed to the references). Basically, depending on what is assumed for a number of parameters, it appears either quite likely that there is life outside the solar system, or quite unlikely. However, at least one has a better handle on what the quantitative factors are that go into estimating this probability by this kind of investigation. \n\n\nB. Reasoning Behind my Opinion\n- - - - - - - - - - - - - - - - - - - - -\n\n\nMy own opinion, after having read this material and some of the links contained, is that it is quite possible that life exists beyond our solar system, or even possibly does or has in other places in our solar system than earth. \n\nFirst, consider the very large number of stars even in our own galaxy (200-400 billion) and the large number of visible galaxies. This leads to about 7x10^22 stars in the visible universe (according to  Dr Simon Driver of ANU). This is more than 10 times the number of grains of sand on earth. This is 100 billion times more than the number of letters in the 14 million books in the Library of Congress. If this is coupled with the seeming presence of a large number of exoplanets around these stars (170 found as of the end of 2005, and we have barely started looking), then this translates into a HUGE number of planets. With this extremely large number of potential planets, there are bound to be some like earth. \n\nLife seems to thrive readily, since life started soon after the earth cooled and existing in environments that we can barely imagine, like miles underground, or near deep ocean vents, or under the Antarctic ice. It has been well known for years that there are amino acids, the building blocks of life on meteors in space. Scientists have also created amino acids in environments similar to deep space environments (see reference). The Miller-Urey experiments in the 1950s were also able to readily create amino acids in environments meant to duplicate a primordial earth environment (reference below). \n\nWith the evidence that there are probably many planets with eart

I agree whole heartedly, but I don't agree that there aren't aliens in our galaxy. You have to be STUPID to believe we are the only thing alive in this universe.

These are good questions, and about the only way to answer them is by example.\n\nImagine you live in Australia and someone in England tosses a bottle with a message into the ocean.  Now -- assume that bottle never gets washed up anywhere or caught in seaweed, but just keeps on floating around and around, what are the chances of you finding that bottle if you go down to the beach and watch for it EVERY DAY.\n\nNow multiply that by a billion and you have a general idea of how big space is and how unlikely we'll detect radio signals from intelligent extraterrestrial life.  But it's worth listening anyway.\n\nAnother assumption that you didn't consider -- Humans have only been using "radio" waves for a little over 100 years.  SETI's assumption is that we're either going to catch an alien civilization at the time when they are using radio to communicate, or that aliens broadcast in radio in a conscious attempt to communicate with other lifeforms.  That's a pretty big "if".

Spontaneous combustion is real although it's causes are not understood.  I wouldn't spend too much time / effort worrying about suddenly bursting into flames though, it is extremely rare.  Aliens might exist although undeniable proof of their existence has eluded us up to this point.  It is likely that somewhere on one of the hundreds of billions of planets in our universe life could be and is supported.  I'm guessing we will never encounter them during our lifetimes, and probably not for thousands of years to come, but if we keep looking who knows what we will find, or what might find us.

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

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......

I have never seen UFOs or aliens, but I think it was a sufi man who observed the following...he said: If you build a 7-story building, it does not make sense to occupy the ground floor and leave the rest unoccupied. He was referring to all the zillions of stars and planets in space that God created...meaning it does not make sense thag God would create all that and have life on earth alone. Having said that, I can not say with certainty that there IS life on other planets, but I can not say with certainty that there is No life on other planets either...but I have to admit; that sufi man's remark makes sense...don't you think? :)

Id like to go to Mars because i really want to know if there are aliens or not.  Nobody knows if Aliens exist or not and id like to find out.  A bit freaky, ain't it?

Lets look at the maths. If every star in this galaxy was a grain of sand ( approx. 100 billion ) you would have enough sand to fill an Olympic size swimming pool. how many habitable planets around each star ? Between 0 and 5 maybe. \n  There are approx 100 billion galaxies. Again if each star was a grain of sand  there would be more sand than on every beach on earth. The chances are there is life elsewhere and in all probability the seeds of life on earth came from somewhere else  as explained by the panspermia hypothesis.\n   And the alien abductions? ,,,we're just studying  8)

When we have answered the question "Do aliens exist?" we certainly would be able to answer them too ;-)

I haven't seen an actual alien but I did one time see something pretty strange.  It was a fourth of July and we were at my uncles house.  All of us were outside in the back yard watching the firework show that was going on in the city.  My uncle looked up at the stars and saw what looked like three stars that formed a triangle.  They were unusually bright.  He pointed it out to everyone and we were all looking at them when suddenly they zipped off in opposite directions.  It was the strangest thing.  All of us just kinda looked at each other and said, "Okay" and never spoke of it again.
