Do aliens exist?

Answer:
There is a very simple answer to this question: "We don't know, but it's possible"

No evidence for life has yet been found on any other planet except Earth. However, this does not eliminate the possibility of extraterrestrial life existing on planets we have never been to. Opinions on the prospects for such life are shown below. The only answer that is factually correct is "Maybe". It is impossible to prove the absence of something. Until evidence proving the existence of extraterrestrials is uncovered, the answer will remain closer to "possibly" than "probably".


Additional Opinions by Contributors:
  • First, when I say "aliens" I don't mean those spacefaring civilizations in science fiction that come to Earth and abduct you. They could exist, but it's all just fantastic science fiction with no proof. What I mean is life outside of Earth in general. I think it is almost impossible for extraterrestrial life not to exist. It doesn't matter if we never encounter them, it's more a matter of probability than anything else. Just think about these numbers: There are about 300 BILLION stars in the Milky Way Galaxy alone. A fraction of these stars are expected to have planets that could support life. That's still in the billions. There are between 100 and 300 BILLION galaxies in the known Universe, each galaxy containing billions, sometimes trillions, of stars. How can you possibly believe that there is NO chance of life arising on any one planet, orbiting any one star, in any one galaxy? Even if you believe that God directly created life on Earth, it would be extremely arrogant to believe that He created this unimaginably vast Universe just for us.


  • Ultimately speaking, the answer is Yes; it is both philosophically and scientifically impossible for there not to be, given the infinite possibilities of Creation. However, "aliens" in the popular sense since World War II as being UFO people is quite another complex question. If you're earnestly interested in this, begin by reading all the works relative to the subject of UFOs by Dr. Jacques Vallee & by Dr. J. Allen Hynek.



  • It is likely that there are aliens. There are so many infinite universes and planets and solar systems that there must be other intelligent life. We don't know for sure if they exist, and vice versa. My thoughts are that they are likely superior to us. If they have UFOs and can travel millions of light years to find us, they probably have superior technology. But, being ignorant, conceited homo sapiens, most of us would think of them as inferior beings. We probably shouldn't refer to them as aliens - they would probably consider us aliens. Some of us would be smart enough to recognize them as normal, thinking, living beings. Who knows? They may look just like us. Or they may be like the green aliens many of us draw. No one knows the facts, but there is at least a strong probability that other lifeforms exist in the universe.



  • The usual argument for the non-existence of alien life is that none have openly contacted us here on Earth. Advanced civilizations might have good reasons for not doing so, or, as could happen with us, they may have reached a point where they gave up on space exploration. If so, they would have ceased to exist once their parent star went through its evolutionary cycle (The Main Sequence for most stars) and died; depending on their initial mass they either turn into a white dwarfs, red giants, or supernova.


  • UFO's and eyewitness testimony notwithstanding, there is no positive evidence that the Earth is being visited, or has been visited, by intelligent extra-terrestrial aliens. This is a commonly used theme for science fiction because life elsewhere in the universe is strongly probable.

  • Most likely there are other living creatures in the universe. There are something on the order of 200 million galaxies out there. So the probability exists that we are not unique and not alone.
  • One important thing to consider is the vast distances between the stars. Even if there were an intelligent technical culture of organisms in our own Milky Way galaxy, it would take other technologically advanced creatures many years traveling at the speed of light to get to us. By the time they arrived here their own home planet would have aged so much that they would not have any relatives they could remember when they returned.
  • About the only way we could be visited by extra-terrestrial beings is if they had the ability to manipulate both time and space. And the way to do that is with quantum physics. Then, maybe, our three dimensional world could be found among the million and traversed by going through the other dimensions. The current Superstring Theory suggests that there needs to be 10 dimensions plus time - the eleventh dimension.
  • If you mean to ask "Are aliens real?" There may have been evidence of aliens ranging from as small as 2 inches to 20 feet. However, many also believe that this evidence may be false in a way. Thinking of how big this galaxy, all the other galaxies known to mankind, and others out there to discover we possibly can not believe that we are the only form of live overall. Although, this my opinion and for now my answer would be no.

  • They would have to be because of all the other planets out there.

  • If you're speaking of extra-terrestrials, only in theory. None have been discovered, communicated with, etc. at this present time. There are plenty of universe and there are great possibilities that aliens live one of the galaxies like Sagittarius dwarf galaxy.



  • There are no aliens known to exist, just a bunch of anecdotes, and no matter how high you stack anecdotes, they never become evidence. We hope there is other life out there, and we consider it likely. But someone has to be the first form of intelligent life in the universe, and there is no evidence that it isn't us.

    While Hollywood has made a number of nifty films about aliens, no such movie constitutes scientific proof, even if it is claimed that it is "based on a true story."
