Has anyone seen an alien?

If anyone had seen one and been able to prove it without a doubt, you wouldn't need to ask the question because it would have been all over the news.  Unless the government covered it up, that is...  I think the government is likely to cover something like that up if it found out (and could cover it up) because of the likelihood of a mass panic.\n\nHowever, beyond a doubt there are other planets in the universe.  Astronomers have worked out their existence with high-powered telescopes.  And that -was- on the news a few years ago.  So hey, ya never know.

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.

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.

considering all the illegal immigration talk lately of course i believe in aliens...ok, crappy joke aside...\n\nits rather conceited for humans to think that in the huge vastness of time and space that there is us and only us...i'm rather on the fence as to whether there are or aren't aliens in the universe, its a question that will only be explained when technology can accurately answer it and not a moment sooner...unless of course little green men suddenly start landing here asking to speak to our leaders...

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!!!

Well, no, but if you are asking if there are aliens, then NO, THERE ARE NOT!

Yes, I believe in UFOs and ALL that other stuff...lol..actually I have seen many objects throughout my life. A few include a massive rectangular object in the sky the size of a football field that would have taken your breath away. \nMore recently in mid afternoon, I saw a silver disc object in the sky right above me as I was in the boat fishing in the middle of my lake. It blew me away.. after watching it for a couple or few minutes it shot straight up into the blue sky. It was unreal the speed of the craft..and it was instant speed..speed we dont have here..\nAnother more recent was during the last summer at my lake.. around midnight... August evening.. I saw an elongated white diamond light at the edge of my lake in the west north west sky..it struck me as being very strange..Its intensity grew to the intensity of a very bright spot light over the few minutes that I watched it..I was on my boat laying there looking up at the stars when I spotted it..I was freaked right out when it became brighter..I had thought maybe something was burning up in the atmosphere..then I realized it was not moving ..I was ready to run but thats when the object dimmed and then it shot straight up into the night sky...the speed was unreal.. \nSame lake last summer my buddy and I saw  a orange glowing sphere just sitting there in the sky..the object was itself was orange. We watched it for a few minutes then I tried to get closer but eventually lost it as I was moving through the trees. \nAlso this fall I had spotted a backwards c in the sky..it was like a jet contrail white but it never changed appearance..and it travelled west. I watched it for 45 minutes as it past right by a jet airliner heading east..real close..then it eventually dissapeared out of sight in the western horizon..\n\nWe brag we are intelligent..\nWe are too young to be as smart as we claim. \nThe first step to intelligence is to realize we are not intelligent.

No..but if you are lucky enough to actually witness their technology..: UFO/disc/sphere/..etc..it certainly closes any doubt involving the questioning of the existence of extraterrestrials. I have been witness several occasions..day and night to objects in the sky..I certainly wasn't looking for them..I just happen to look up at the right times..but perhaps in the near future if we are lucky ..we can get more governments throughout the world to come clean..and fill us in..on what many believe and some even know...that we are not alone..here or the universe

There just has to be life out there. I thought I had an experience with an alien but it was my mother-in-law.

Aliens as we see in our movies, no.  But I wouldn't presume to think that we are the only living creature in our galaxy.  It's only a question of time and where.  Considering the time and distanc involved, we may never meet.

I saw a banshee when I was little. She was sat outside the doorstep of a sick neighbour of mine. Here's more info about them http://www.irelandseye.com/animation/explorer/banshee.html

If you mean aliens that have visited Earth then NO.  Sci Fi bullsh*t that deserves no airtime at all.  If you mean the existence of life on any planet anywhere in the Universe then undoubtedly it does exist.

I feel some clarification is in order. ANYTHING that you see in the sky that you are unable to identify is by definition a U.F.O. Calling something a UFO doesn't automatically make it an extraterrestrial spacecraft full of little green men. I have seen plenty of things in the night sky which I could not identify, so yes I have seen many UFOs but I don't think I've ever seen evidence of extraterrestrials.

Yes I have seen them all of my life...Just to name a few that I have been witness to ..A huge rectangle object that could take an entire football field to land. A silver disc right above me in the middle of the afternoon as I sit on the lake in my boat fishing..then it shot up and gone with instant speed..speed we do NOT have...an orange sphere...silver balls....a backwards c shape object we followed for 45 min...an elongated diamond that shone an intense spotlight on me before it shot up into the night ...then the very most recent was last month.\nIt was a windy night and not really that nice out, no rain just not nice. I decided to go to grab a bag of blankets from the RV that's parked down by the lake. I headed out from the cabin and was half way there when I looked at my watch and it was 12:01 am Sunday May 7th. I then went inside to grab my bag of blankets. I was in there for maybe 15  seconds and I then stepped outside and was facing west and there, right in front of me was a elongated diamond light sitting in the western sky. It was the size of the moon. If you imagine the moon being shaped to that description of an elongated diamond it was similar to the one I had witnessed last August here, but there was a dark circle in the middle of it. I stopped in my tracks as it took my breath away.\n\nIt was very clear, very visible and so very out of place. it was approx. 1/4 mile away and 300 - 400 meters up. I stared at it for about 4 or 5 seconds, suddenly there was a bright flash that lasted about 3 seconds. I quickly thought maybe it's a meteor or something burning up in the atmosphere, due to the intensity of the light, but I realized as it went back to it's original intensity, again that was not the case. As I already knew deep inside me and the fact the object wasn't moving. It sat there for another few seconds then it started upwards and towards the west and in an instant it was as small as a tiny star. I then followed it as it turned south for a second and shot up straight into space. Yes they are real..I have seen them all of my life
