can any one tell me if life is in another planet?

in our solar system i would say unlikely, but in the universe it should be. but we don't know that yet.

Not yet. Organic molecules, considered as precursors to basic life forms, have been found throughout the Universe (mostly in comets, interstellar gas and dust). Experiments show that some bacteria and archaea can survive the severity of outer space. So it's quite possible that we find living organisms in the future, most probably on other planets.

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.

There is a possibility of other living matter existing other than the humans.There are billions of stars and there may be many more earth's around them.When the conditions of existance of life prevails ,like for earth -water,atmosphere,essential gases and many more exist.Ofcouse there may be different conditions in other galaxies but there is a possibility that life exists.Them being friendly or visious depends upon the way we try to communicate with them.If the way we communicate is wrong they may prove to be more visious than friendly.

Still no life is mars,\nLet mars be the beautiful. if life comes there also then it will be earth.

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.

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".

1.  On Mars, yes.  It's only microscopic life though.  Sedna, I have no clue.\n\n2.  Go here.  It'll provide a great answer to your question.  http://www.pbs.org/wgbh/nova/sciencenow/3210/01.html

Chances are, yes.\n\n90% of all solar systems are not in a circle so they can not support life.  Of the 10% that are left what are the odds that another planet is moving around a sun where it's not to hot or too cold. Even in our own little solar system there is only one.\n\nSo, if there is life elsewhere, we will never meet them.

if ur asking if we, as humans, can be sure the no one else exists on the other planets? then no..no one can be so sure, but the facts gathered about the other planets, such as chemicals in the air, etc... can tell something about the planets..

There could be another planet ... but it will be so far away from the Sun that it may be even more difficult to find than Xena (the 10th planet).\n\nAs to the solar system existing in another planet?  Hmmm .... seriously mate ... no.  Not a chance.

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.

not in our solar system. \nBut you also have to remember that even if there is life on other planets, we are assuming that they are as advance as we are or more. Could it be that maybe they are in a pre-industrial era and have no means of space exploration?

People have always wondered\nwhether or not life exists \nelsewhere in our solar system. \nSomewhere besides the Earth. \nWe humans have never accepted the idea that it is only on the Earth that life has occurred. From earliest times when we peopled the heavens with gods, goddesses and supernatural beings, through our space exploration activities of the 20th Century, we are driven to decide the question:\nIs there Life on Other Planets?\nThe question of UFO's and intelligent life on other planets has become very popular. Many fashionable scientists speculate about the possibilities, insisting that we cannot be alone in the universe. Alien life is the subject of hit television shows and movies, and is also a common belief of many New Age religions. Many people have asked what the Bible has to say about this subject.

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.

Thinking that in an "infinete universe" we are the only planet with life is selfish and stupid...\nImagine: We are in an insignificant planet, at the corner of an small galaxy...\nI think is very probable that exists other intelligent life form out there... \nThe question is: How far away? Can we ever met them? \nI think they are far enough, so we won't have some kind of encounter with them...

I think so!\nIf life exists on the top of the large mountain where there is only snow and no oxygen in the air, then life should exist on other planets!\n\nDo you know that, life exists in deep sea where there is no sunlight! If life sunlight to live, how do you explain?\n\nLife also exist in caves very down in earth where no light is present. They are bacteria! They absorbe heat from boiling water, thats how they obtain their energy!\n\nThat may be quite enough to explain how life may exist in extreme conditions and thus beyond planet earth
