They have found methane,that means there is some kind of organic life

yes, they -or it- exists as u can see nasa found germs,bacteria,exstinct polar ice caps, and even a fossil of a "human" type face on mars! so yes the exist!

Well Scientists have long speculated about the possibility of life on Mars due to that planet's proximity and similarity to Earth. It remains an open question whether life exists on Mars now, or existed there in the past.\nIt has long been speculated that there may be life on Mars, due to the many similarities the planet has with Earth. Mars' polar ice-caps were observed as early as the mid-17th century, and they were first proven to grow and shrink alternately, in the summer and winter of each hemisphere, by William Herschel in the latter part of the 18th century. By the mid-19th century, astronomers knew that Mars had certain other similarities to Earth, for example that the length of a day on Mars was almost the same as a day on Earth. They also knew that its axial tilt was similar to Earth's, which meant it experienced seasons just as Earth does - but of nearly double the length owing to its much longer year. These observations led to the increase in speculation that the darker albedo features were water, and brighter ones were land. It was therefore natural to suppose that Mars may be inhabited by some form of life.\n\nSpeculation about life on Mars exploded in the late 19th century, following telescopic observation of apparent canals — which were later found to be optical illusions. In 1854 William Whewell, a fellow of Trinity College, Cambridge, who popularized the word scientist, theorized that Mars had seas, land and possibly life forms. In 1895, American astronomer Percival Lowell published his book Mars, followed by Mars and its Canals in 1906, proposing that the canals were the work of a long-gone civilization. This idea led British writer H. G. Wells to write The War of the Worlds in 1897, telling of an invasion by aliens from Mars who were fleeing the planet’s desiccation.\n\nBetter telescope imagery, and especially the photos taken by the Mariner 4 probe in 1965 showed an arid Mars without rivers, oceans or any signs of life. Intense UV radiation made the planet extremely hostile to life as we know it. Officially the Viking lander's tests for microbes in 1976 were inconclusive, but most scientists hold that their findings can be explained on the basis of chemical reactions alone. Observations made in the late 1990's by the Mars Global Surveyor confirmed the suspicion that Mars, unlike Earth, no longer possessed a substantial global magnetic field, thus allowing potentially life-threatening cosmic radiation to reach the planet's surface. Scientists also speculate that the lack of shielding due to Mars' diminished global magnetic field helped the solar wind blow away much of Mars' atmosphere over the course of several billion years.\n\n\n\n \nThe electron microscope revealed bacteria-like structures in meteorite fragment ALH84001 \nA series of artist's conceptions of hypothetical past water coverage on Mars.In recent years speculation has grown again, however – prodded by a study of the ALH84001 meteorite which concluded that it contained fossilized microbes. Other scientists have subsequently sought to explain these findings on the basis of chemical processes. Both remain highly controversial within the scientific community.\n\nAnother glimmer of hope for past and present life on Mars has been revealed with the ongoing research into extremophiles on Earth which survive under the harshest conditions. Some scientists have proposed a biological origin for the annual appearance and disappearance of dark dune spots near the polar regions of Mars.\n\n\n\nNo Mars probe since Viking has tested the Martian soil directly for signs of life. NASA's recent missions have focused on another question: whether Mars held lakes or oceans of liquid water on its surface in the ancient past. Many scientists have long held this to be almost self-evident based on various geological landforms on the planet, but others have proposed different explanations - wind erosion, carbon dioxide oceans,

This is a little hard to answer.\n\nFirst, we haven't found any.  So there's no positive evidence, so it's hard to be really sure. \n\nBut on the other hand, there are billions and billions of planets like ours, and it would be really weird if ours was the only one to have life on it.\n\nSo most astronomers think there's probably life out there somewhere.  I hope we find it.

That is currently a hot question in debate which has yet to be answered.  Despite five rovers being sent to Mars there has been no evidence of life, even in the form of bacteria or simpler organisms.  Some scientists believe there exists (or existed) life on Mars and that the first organisms on Earth arrived here from Mars via a meteor.

No I believe there is other life out there somewhere. The universe is huge so how could we be the only planet to have life?

No, aliens are not living on Mars at the present time because the current conditions there could not support life. There is a possibility that life once existed there, based on evidence of previous existence of water. The "face" and "pyramids" that you're talking about on Mars are just glitches in the photography that have been proven to be incorrect.

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.

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.

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.

having life only exist on earth is like picking up a single grain of sand and saying that that grain was the most perfect grain in the entire world...it would be impossible to know this unless every other grain was examined, and the fact the new grains are constantly being made.  there are over 200 billion galaxies in the visible universe and a couple hundred billion more out there, all containing stars and planets that maybe able to sustain life.  and by "life" that also takes into account of any micro-organisms like bacteria and viruses and any other forms of life that might exist.  So to say that there is no life on other planets would be incorrect to assume, it's just a matter of time in trying to find it, whether it exists in our solar system is still debatable as micro-organisms can live in harsher conditions that larger organisms arent able to

I am almost 100% certain that life DOES exist on other planets, and may be in completely unfathomable ways, that we could not begin tio understand.\n\nIt us very interesting that the prospects of life having once existed on Mars are become more likely, due to the significant discovery that water once was in abundance there.\n\nThe trouble with finding life in other solar systems is that the distances are just too great. Even radio waves take 4 years to reach the nearest star from the Sun, then you need 4 years for the reply. The majority of stars are MILLIONS of light years away. so EVEN if there are a Billion planets with intelligent life there is no way of being in contact.\n\nBUT I do hope I will find out that DEFINITE life has been proved to exist before I die.\n\nI find this a fascinating subject.

are you living in Mars??

Yes i have some interesting facts about mars!!!The belief that there may be life on Mars was popularized in the 19th century, mainly due to the announcement of Martian canals from the observations by Percival Lowell and Giovanni Schiaparelli. Schiaparelli called these observed features canali, meaning channels in Italian. This was popularly mistranslated as 'canals', and the myth of the Martian canals began. They were apparently artificial linear features on the surface that were asserted to be canals, and together with the seasonal changes in the brightness of some areas, they were thought to be linked with vegetation growth. This gave rise to many stories concerning Martians. The linear features are now known to be mostly non-existent or, in some cases, dry ancient watercourses. The color changes have been ascribed to dust storms. \n\n\n\n\n\n\nThere isn't any that we've yet discovered. But there's plenty of evidence that there was once water, and so possibly there was once life, although we've yet to discover any fossils or anything like that. If there was life, it was probably only microbial. But hey, it's a whole planet, who knows what we'll find. \n\n\n\nThere is no life on Mars, however their are all the signs that life was their once since their are large river like gorges covering the planet. Since then Mars' core (i think) cooled to low to support life and so everything cooled. Search for life still continues with little success. \n\n\n\nLife on mars is very possible. It would probably have lived a looooong time ago, back when mars probably had water. Most of that water is frozen in permafrost now though! A mars mission would look for fossil es as well as signs of water being on the surface.

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.

Yes i think they exist, but they are definitely not on mars as people think,their brain is on mars. It doesn't mean that if on mars everything is suitable for a human,these aliens may have other air, food.. that humans don't that we don't know.The extent of the universe is unknown, there may be many of them or even humans that are many light years from us and they cant reach us.

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.
