I think we would be very naive to believe we are the only life form in the universe.As vast and diverse as it is,I believe there has to be a reason for the formation of these planets to sustain life.That said,who knows when the life was present on these planets?And who knows what life forms are out there as we speak?Perhaps Mars and Pluto had life trillions of years ago but there are no remnants now for us to find.It's a fascinating topic.If you think about the possibilities,it's incredible.

greetings....\n\ni actually believe that we are not alone...i have my own encounters... the universe is big....so big we cannot even start to comprehend how big it is... chances are, life could actually be abundant in the universe, but the degree of intelligence could vary widely, maybe life exist only in microbial form, or with intelligence much superior than ours... but for now only earth is known to harbor life... aren't we lucky we are here?

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.

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 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.

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

I think so.  Given the probable number of other planets (nearly infinite), it defies logic to think that Earth is the *only* place in the universe that life developed.\n\nI have not had any contact with extraterrestrials myself, however, so I am not speaking from personal experience.\n\nEdit 3/16\nAfter posting my answer, I watched a show on the History Channel about Meteors.  One of the things the show presented was a meteorite that is believed to have come from Mars and *may* have signs of fossils embedded in the rock, fossils of living organisms -- bacteria.  The meteor is called ALH 84001.  Here is a website about it:\n\nhttp://www.lpi.usra.edu/lpi/meteorites/life.html

I believe in "BIGFOOT". No I dont have proof,but theres no proof he isnt real! I know people who know what they saw and I believe them. The scientific community does not have all the answers.There may be lots of things on Earth that have yet to be discovered.The paranormal cannot be explained,yet something is going on. I have been witness to unexplained phenomena many times. I know what I saw and heard and I was a skeptic once.

Sounds like you already know the answer to your own question...:)  Bottom line:  there is considerable evidence that there was once at least simple life on Mars.  There is some evidence that there may be simple life there now.  There isn't conclusive evidence of either of those things...so if we want to know, we need to keep exploring!

of course. As long there is a living thing outside space, they r aliens. The possibility is low but the no. of planet is almost infinity so the possibility increases.

This is a highly debated question.\n\nFrom a religious aspect, many Christians believe human life is unique.  Hindu scriptures tell of many planets with many different life forms.  I am not familiar enough with other scriptures to hazard a guess.\n\nThe only scientific arguments I am aware of follow a probabilistic argument.  Unfortunately these fall into the same two camps.  "If there were life we would know by now."  Or the argument estimating that in a universe of our size, there would probably be x number of earth-like planets, with a certain percent evolving into civilizations capable of interstellar communication, and it is only a matter of time, before we hear from one.  SETI is one project I know of  searching for Extraterrestrial Intelligence.\n\nPersonally, I think that if such life exists, it may be so alien that we would not recognize it as all.  I also hope we get our act together, before we suffer intergalactic embarrassment.  Let's learn to get along with one another first, before embracing our alien brethren.

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.

Alien? What's that?\n\nI think there is a huge statistical probability that LIFE exists somewhere else. And that may be as simple as uncicell forms of life. It may also be another form of life we've never seen on earth.\n\nBut "aliens" as we see in movies, sure not!!!

An alien, literally, is someone who travels (and possibly lives) in a region or country he/she/it does not really belong in (due to polits, culture, etc).  So, I believe in aliens from other countries ... there are enough of them all over North America :P\n\nBut then aliens from other planets is a little too much to digest. \n\nWell, then again ... it's hard to believe that with the size of the universe, we're the only form of life in the ENTIRE place.  So, there is other life, or at least I'd like to think so.  \n\nBut it's scary to think that this other life has actually travelled God knows how many light years to get to our planet.  The only form of life that there is in our galaxy that we know of is the bacteria that is found on Mars.  So whoever these beings are, they'd have to travel from some other galaxy out there somewhere ... And if they actually did, it shows that they have way more technology than we do.  \n\nSo I'm better off believing that there are no aliens ... in the sense that we have yet to receive visitors from outer space.

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!

At the present time, we just don't know.  If you saw pictures of aliens, what you saw were fake.  Nobody on earth has yet to produce a verifiable image, photographic, electronic or hand-drawn, of a living creature that originated elsewhere in the universe than from our home planet.  Nobody.\n\nAlso, at the present time, we suspect that there is no other planet in any nearby solar system that's host to a sentient race of beings like us.  That does not mean that some form of what we call "life" is impossible, but just think: out of the billions of living critters that now inhabit, or did in the past, our home planet, only one of those life forms evolved to the point where it (us) can even begin to think about such questions.  That by itself will tell ya we're sorta unique! ;-)\n\nIt sure would be interesting, wouldn't it?  But imagine if you will what it might be like if those alien creatures we fantasize about were an advanced race of carnivores that look upon us as another breed of cattle, fit only for eating!  Yow!  Or, how about if they were friendly, warm and fuzzy folks who just love to make nice with us - but they carry an infectious disease that there's no cure for.  Oh boy.  Or maybe, like Darth Vader, they just consider us a nusiance worthy of one blast from a super-mega cannon that blows Earth into dust?  Whoa!  Hey dude: you SURE you wanna meet aliens?  \n\nAll this is just idle speculation.  The hard fact is, even if there were creatures just like us somewhere in the universe, we are not gonna know about it, because the distances between them and us are just too great to permit interstellar travel, the hazards of such a trip are insurmountable, and no means of communication can travel fast enough for us to hear from them and be able to answer back.  Kind of a bummer, isn't it?

I believe in the possibility of aliens. My theory is, why not? why would we be the only living beings in the entire universe?
