if you believe aliens exist, give me LOGICAL reasons why?

Hehhe.  If you really knew what they believed, you'd never look at Tom Cruise the same way!\n\nYou really should just go read the Wikipedia page on it, as its simply too much lunacy for me to post without busting my gut laughing.\n\nEssentially, they believe in aliens.  But they believe some things about these aliens that make the simple belief in aliens seem rational.  :)

Alternative. ie; I think I saw a UFO, can someone tell me who to report it to please? or -  I believe in UFO's, who else does? or -Why are aliens so weird looking? or Can aliens exist in my brain cells? or......

I do believe in aliens.  I've seen Tom Cruises' child.

Yes, I believe in intelligence outside of our own shallow planet. As for UFOs I can say they are real..I have seen many objects both day and night, for all my life. I believe.

Like they said in the movie Contact, I don't know, but if not that's an awful waste of space.\n\nYes, I believe that life exists in some form out there. I'm not sure if I believe they are "among us" but I do believe we have a lot of unanswered questions regarding UFOs. \n\nThe government hiding things from us? Awwww. You don't think they would really do that, do you? You'd be amazed at how much our government keeps from us. I worked in military intelligence at one time. There is something called "a need to know." And who do you think decides who needs to know?

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 scientific proof for Santa Claus (except for NORAD, maybe), contested or otherwise. A large body of contested data proving aliens' and God's existence, and some evidence claiming that God is an alien!\n\n"Believing" there must be a planet out there that can support alien life is not evidence, folks. It's blind faith. Not saying there isn't one, just that no one can say there is yet. And you people pick on religious believers for not having any proof...

Aliens seeded us on this planet, but they'er not extraterrestrial beings. They are subterrestrial, living deep within the bowels of the earth. They have been here for a very long time. In the bible it says God had walked up to Abraham with two others, supposedly they were angels. I believe all three were "aliens". \n   God, on the other hand, does exist. But what is God? What form? Nobody knows. This God created everything: us, the aliens, the universe.

I think aliens exist, but I don't think they live among us. Think of Earth and all of the cosmic and environmental factors that are required to sustain and promote life.  I think it would be unusual for similar conditions to exist in other galaxies that will produce intelligent beings that look exactly like humans.

I don't think a credible claim for seeing aliens exists.  Plenty of stories - zero real evidence.  \nDo they exist?  Well, I think the answer is probably.  There are so many zillions of planets in the universe, I would bet that there are others with life.  However, unless the time scale on which that life lives in FAR longer than ours, the laws of physics do not allow them to live nearly long enough to visit us.  It would take many millions of years to go out and visit these other planets - improve rocket technology even 1000x and it would still be thousands of years.  \nHowever - the possibility of us picking up some sort of radio signal from an alien world seems to be real.  No real hits yet - but it may happen.  We have conducted transmissions that have been sent to star clusters (containing millions of planets) which, if any have the same level of technology as us, should be able to pick it up.  Who knows.

If aliens exist, it proves that there is no God, least the god we know. \nThat or there are more than 1 god to make beings in thier image (or not in there image, whatever the case may be)

Lets assume five things:\n1) Aliens are extremely advanced.\n2) These aliens have the technology to travel through space.\n3) These same aliens wish to study us.\n4) These aliens have catch and release laws / ethics.\n5) Finally, these aliens do not want to be detected.\n\nIf I need subjects to study and I cannot just dispose of them, I want to pick subjects whose report of me is going to be discounted as 1) a dream, 2) a hallucination due to drink / drugs or 3) someone who is just plain dumb.  Or even better some combination of the three.\n\nThis way I get to study silly earthlings, and as my subjects report me and the tests I run, you all laugh and joke about him / her being a dumb hick.  Meanwhile I have hundreds of years of data accumulated.\n\nJust my thoughts.

no one has been abducted by aliens\n\n\nthose who claim that they have been are very, very bored

I don't believe that there is any tangible proof that there are aliens, but I have always believed that there are. Just considering the amazing size of the universe, it seems unlikely to presume that there isn't other life out there somewhere, perhaps even "intelligent" life.

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.

If aliens do indeed exist ( and, given the vastness of the universe, it seems likely ) we cannot know their state of scientific knowledge.  Given an advanced culture, one would assume that elements would be placed in some sort of table based on the behaviour of said elements, and would almost certainly be identical to ours in structure.\n\nIf you're asking about different elements beyond the ones we know, well that too is a virtual certainty; we make new ones all the time...I don't doubt that there are many more than we know about.\n\nWell done for thinking about these things.\n\nEDIT :  Existence is existence, whether an atom of an element exists for a microsecond or a million years.  Furthermore, although many elements are unstable - in order to BE unstable, an element must first exist.  Moreover, well...let's just say islands of stability and the show ain't over 'til the fat lady sings....
