is there any extraterrestrial life out there in the space?

if theres not i would be extreme surprised.  the universe is so huge that it would be ridiculos to assume or think there isnt.  even though we have only explored probably less then 1% of the universe we have still found planets that we think would be able to suport human life (remember not all life would have to be carbon based like us either) so even if there isnt a planet that we could live on some other type of creature might think its paradise.  the answer to your question is yes there is most likely life other then ours out there somewhere. although it would depend on what you mean by "life" if you mean intelligent life i still think yes there probably is although they have found fossils of bacteria on mars so technically that means there was at one point there was life in our solar system other then earth.

All sorts, it is almost invetable that the universe MUST be teeming with life.\nBillions of planets, millions with life.  Possibly billions with life

The probability of life on other planets (or moons) is certainly given. Just the other day a spacecraft found liquid water and volcanic activity on Saturn's moon Enceladus. So it's quite possible there could be life, in a primitive form at least, as near as Saturn's environment.\nAs to other galaxies, we'll never know. It's too far away - we're talking millions and billions of light-years. So even if there was life in other galaxies, the information to reach us would take millions and billions of years.\nGoing there is out of the question. Mass can't even reach the speed of light, meaning that to go to the nearest star, Alpha Centauri (four light-years away), would take very long. With a Space Shuttle, you can go at 28000 kph (17,500 mph). Light travels at 300000 kilometres per second (186,000 miles per second)! This equals 1080000000 kph (675,000,000 mph).\nSo given today's technology it would take slightly more than  150,000 years only to reach Alpha Centauri.\nBetter make sure to have a good book on board with you.

I'm not after the points as much as I'm want to give my views on the matter.\nAliens... I believe there must be life somewhere in the Universe other than Earth, given that it is so big. However I don't believe for a moment we are going to have visitors from other planets. The green men thing is all bullsh*t to me. If there is some other form of life somewhere in the Universe (very far, I expect), I expect it must be microbiotic or something of that sort. And I don't believe the "end of the world" will come from the space either, that's plain stupidity. \nThere you go.\n\nET phone home!

Nobody can prove it. And nobody can disprove it.\n\nAnybody who says there definitely is life in space is a fool. So is anybody who says there is definitely NOT life in space. \n\nWe just do not know.

1.) The chances are about 100%, plus-minus 0%. Primitive forms of life (i.e. cells) have been discovered on Mars and on some asteroids, the question is, whether there is intelligent extra-terrestrial life. And I find it hard to believe that there wouldn't be, given the infinite size of the universe and the laws of probability. \n\n2.) No, I don't believe in mermaids. Leprechauns, now that's another story...

Using mathematics to determine the chances of life elsewhere in the universe, one estimate determines that there are approximately 10^75 advanced societies.  If true, then it is very likely that there is life beyond earth – even advanced life forms.

I doubt that there is life there or elsewhere in the universe. Yes there is ice in outer space and probably on portions of planets which means there probably was water out there at one time. However there are too many variables missing for there to be life as we know it. Believing that there are physical life forms other than as we have here on Earth is just speculation. The more space is explored, the more we know that Earth is uniquely made. If you get a chance see the dvd, "The Privileged Planet".

I don't believe that there is any tangible proof that there are aliens, but I have always believed that there are. Just considering the amazing size of the universe, it seems unlikely to presume that there isn't other life out there somewhere, perhaps even "intelligent" life.

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

There are many schools of thought on this. \n\n1. There is no other intelligent life in the universe.\n\n2. There is other intelligent life but it is too far away to contact us and vice versa.\n\n3. Other intelligent life has existed in the past but died out before humans evolved.\n\n4. Other intelligent life has contacted us but we are unable to comprehend their communications. Their calls have been unnoticed. \n\n5. Intelligent life has contacted us. \n\n6. There is other intelligent life but we cannot detect them because they no longer use high power radio/electromagnetic communications (our society is moving toward this situation.)

Of course there is.  You would have to be crazy to think we're the only ones in the universe and the parallel universes, and so on.  They found rust on Mars, which means there was water - therefore leading to the conclusion of life on Mars.  If there was life on Mars, you better believe there's some kind of lifeform billions and trillions of light years away.  No life was discovered yet because we haven't built rockets that are capable of taking us to the destinations of where we haven't discovered yet.

I wouldnt say there isnt any life outsdide our solar system. there can be a very high possibility that there is inteligent life out there.

It is more likely than not that there are many planets in the universe with life and many of those may have "intelligent" life.\n\nWe have just only obtained the ability to detect planets in other solar systems and we can only detect very large ones. We do not have the ability to detect Earth like planets.\n\nWithin our own solar system, we have yet to find undisputable evidence of life on any of the planets we have activley searched for it. Many scientists are optimistic about finding microbial life forms within our solar system though. There are still pleanty of places on Mars, for example, that we simply haven't looked, and there are many moons in our solar system with the potential for supporting microbial, and even more complex life forms. Jupiter's moon Europa is a good candidate because it is covered by a sheet of ice and thought to have liquid water oceans underneath. Due to Jupiter's gravity constantly tugging on the planet, it is likely geologically active and thermal vents may exist in it's under ice oceans. Here on Earth, underwater thermal vents are teeming with life, even though no sun light reaches them.

No one has yet shown that there is any life beyond that on Earth. \n\nAs far as life in general is concerned I am reasonably sure that there is life on other worlds and there are currently a couple of space missions in development that may find earth-like planets and even find signs of life on those planets in the next few decades.\n\nWhether there is intelligent life out there is more debatable.\n\nConsider that in 4.5 Billion years the Earth has only produced one technological intelligent species. This species has only really been able to consider possibly contacting or being contacted by intelligent beings from another world for the past 50 years. In that time we have just about managed to avoid nuclear annihilation, so far, and are currently well on the way to destroying the Earths eco-system.\n\nIf intelligent life is anything like Homo Sapiens then it will probably not last more than a few hundred years at a level where it is technically able to contact others.\n\nGiven that, it is extremely unlikely that two intelligent species will evolve close enough together to contact each other in the short time frame that they are able to do so.\n\nSo while there may be intelligent life elsewher in the universe I doubt we will ever find it.

hehe...I dunno...how do you spell intelligent?  ok, that was mean, sorry...I think there has to be intelligent life out there somewhere...it's not very plausible that this one tiny little planet is the only one that can sustain life in the entire universe...
