Aliens, do you beleive there is other life out there?

Definitely.  Even if its just some microbes out in space, just the sheer number of planets and stars etc I would think there would have to be other life out there!

I've seen an alien, they're in the form of light. and aren't reflective. They dont have bodies, and they communicate at radiowaves so high we cannot hear. they dont have faces.

Probably,\n\nI don't know if they are walking talking aliens, but I wouldn't be surprised to find out there are other forms of life that didn't start in our solar system.\n\nAfter all, there are billions and billions of solar systems. Are we so self-absorbed /self-involved that we think this could only happen to us.

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.

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.

No, there is almost certainly life within the Universe besides Earth, and there is certainly life within the Milky way besides earth.

UFOs do exist but alien abductions are bogus. I could tell you why. I could tell you lots of things, but you wouldn't believe me anyway.

There is no evidence that alien species from other worlds or other galaxies have ever visited Earth. The examples given have all been debunked by numerous scientists. We'd like to believe there is life out there, but we haven't heard from anyone yet. Because the distances are vast -- measured in hundreds of thousands of light years -- it is more likely that we would have radio or television transmission, which travels at the speed of light, than a visit in person. Maybe they're listening to our TV broadcasts and don't think we're intelligent enough to contact.

A recent scientific study estimates that there are AT LEAST 70-sextillion stars in the universe, one of which is of course are own sun. The odds AGAINST none of those other stars having planets occupied by sentient life are astronomical (pun intended). Undoubtedly of all the life forms that exist in the universe some are technologically at the same level as we are, while others are at least several thousand years ahead of us. Still others might be where we were 3-million years ago---just down from the trees. Certainly, any alien life with any intelligence at all must wonder if there are other life forms somewhere other than their own world.

aliens by the look of it

i also think aliens exist. out of all solar systems all the planets all the galaxies in the universe we can or should never argue that we are alone.

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.

it's a hard question to answer, cuz same as you can't be certain aliens don't exist, you really can't know for sure if they do !! Although I can't say they exist ... i don't really see it impossible ... they "might" exist ;)

So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.\n\nWhy haven't we heard from them?\n\nPerhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.\n\nPerhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that just flew by may be a surveillance craft.\n\nPerhaps they are so far away they will never notice us and vice versa.\n\nPerhaps they existed a million years ago and died out.\n\nPerhaps they will exist a million years from now.\n\nIt is really impossible to know for sure.\n\nThe Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

Who said most of us believe in aliens?  If by "aliens" you mean life existing outside of Earth, then I guess I would speculate that aliens exist.  If you have the impression that aliens are little green men that visit Earth in UFOs and use probes, then that is just ridiculous.  Considering the billions of stars in each of the trillions of galaxies that exist in our solar system, it seems logical to assume that at least one other planet in one other solar system has some form of life, even if it is only similar to bacteria.  There is no proof, much in the same way that you cannot "prove" that aliens *don't* exist.

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.

I DONT THINK THAT WE R  ALONE . WE HAVE SEEN A FEW SIGNS OF XTRA TERRESTRIAL LIFE AND IT  IS POSSIBLE THAT THERE ARE OTHER LIVING ORGANISMS INHABITED PLANETS
