It is ridiculous to think we are the only life in this universe. It is equally ridiculous to think that other life out there is 1. As advanced or greater than we are AND 2. Figured out we were here AND 3. Flew here from WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY out there just to stick probes in our butts over and over for decades just to see what we had for dinner last night. Seriously, how many human beings have to be abducted and probed until these "superior" beings figure out our physiology? Also… who are these retarded aliens who crash-landed in Roswell after flying here from WHO KNOWS how far away? (Hint: most likely AT LEAST 4 light years away.) REMEMBER to figure in the "ANDs".

I believe there is no such thing as extraterrestrials. And all UFO sightings are simply drug smugglers who have federal assistance by not acknowledging sighting reports.

It's pretty obvious once you compare UFO sightings and known drug smuggling operations during the 70s and 80s.

Of course aliens exist….of someone thinks WE are the ONLY living beings in the UNIVERSE then they are fucking idiots

AL May 10, 2018 - 4:03 PM

Complete stupidity! This is why we are no more just another species that know nothing. Proofs of aliens are way much more than what this guy says.

NOTROSS May 13, 2018 - 6:11 AM

The only reason a ufo is made, people made a creature, and it was why they made aliens. They dress up, and get people randomly, for projects.

Doofensquid May 19, 2018 - 7:03 AM

the people who arent intelligent are who dont believe in aliens. for real for me its 2018 and aliens are pronounced not a legend but a real specie

Is fake fake fake like nasa big lies in world

Robert Kelly May 26, 2018 - 9:26 PM

UFO could mean anything top secret US man made craft that are unidentifiable.

Arizona Sunflowers June 15, 2018 - 2:06 PM

Yup. They do!

Gerrard Jones June 23, 2018 - 1:38 AM

Aliens do exist but they just don't want to bother with us because where stupid and if we don't do something soon were going to destroy our selves somehow

Maybe nuclear war

We will destroy this planet with pollution and deforestation but we won't have made advanced space technology to escape because we just aren't focused on it were focused on our are little life and our little routine

Maybe a disease will wipe us out

Or maybe aliens themselves

What do u think ?

No Name June 26, 2018 - 4:29 PM

I'm not impressed with this boring ass universe that is essentially a dust bunny.

And we the only dust mites before a vacuum sucks us all.

Trust No one July 31, 2018 - 2:09 AM

We don’t know the odds, it’s like asking a person two thousand years ago what are the odds there are other kinds of bears in an unknown place

Lynn D. August 1, 2018 - 11:03 AM

They only exist in your mind.

R hurn August 1, 2018 - 7:39 PM

Is this a question, so dumb, of course aliens exist, we just haven't been able to pin point exactly where they are, and how could we? The universe is vast, we've explored like 0.0000000000000000001% probably not even that infact. The universe is like way more than 15 billion years old and according to some scientists, there's probably more than one universe. Either way, whether it's infinite or whether there's say an infinite amount of universes, there's definitely aliens out there and some of them most likely look like us, I believe

Ysrail Laks August 4, 2018 - 7:41 PM

aliens are coward and crying baby..always hiding..if i see one how i wish to crush and kick one…

Dave McKay September 19, 2018 - 10:17 AM

so what?

Jack Gephart September 27, 2018 - 3:15 AM

If any of you would pick up a Bible you would know already. Genesis 1:26 God said," Let us make "MAN" in our image." So yes they had made other humanoid creatures that were not in their image. But if this is not enough for you, watch UNACKNOWLEDGED and quit trying to be funny about it. This is a real important subject and getting little pimple face kids to talk about it is an insult to the whole subject.

Peter Osborne December 18, 2018 - 4:00 AM

Wooo hold the phone stop for a second and THINK…. the mathmatical probability that given all the suns,universes in the known solar system that we know about is there life(intelligent or not) as we comprehend it to be …. most likely—-. Well yes , Have we been visited ourselves that we can positively identify as true. NO there is no such evidents, so grow up people get a life.

Weight and Balance and Music December 26, 2018 - 4:47 AM

Yes…probably have life in somewhere in the universe…but..spacecrafts? Aliens visiting us? With big heads, naked, travelling thru space time wormholes? Only to see us? And NEVER,,,,NEVER been photographed ? Or captured? Or contacted? This is ridiculous……life in universe must be very common, but super advaced ,
Probably not…at least nothing in a hundreds of light years around us….probably nothing in milky way…..we was never visited by Aliens…..why not? Because there is no evidences of this….NOTHING…..any single evidence….so….lets gonna keep studing the origens of life and try understand how life began in our planet….then we will be capable to understand in others worlds

Abhay js nair January 14, 2019 - 10:09 AM

I saw a alien today

Chris Moore February 1, 2019 - 5:41 AM

Terry Bessey February 19, 2019 - 6:05 AM

Nathan Croft 97 April 5, 2019 - 1:35 AM

I dont belive in them at all

Dick Longmire April 11, 2019 - 9:03 AM

UFO's or as MUFON and others wants to imply, alien space craft is a load of crap and has been for decades. They don't exist! All sightings are either anomalies or military test air craft. Let’s look at the facts. Not including digital cameras since the early 2000's, smart phones with cameras have been in almost everybody's pocket or purse for years now and yet we have no good conclusive footage or proof. These people get salaries for what they do so they have financial skin in the game. The other funny though that always gets me is they supposedly have advanced technology that allows them to come across the universe from far reaching planets without hitting one asteroid yet as soon as the come to earth, they crash? What? Do they crack open the campaign as soon as they hit our atmosphere so they are FUI by the time they arrive and then slam into a farm field? UFO believers are just plain delusional grassy knoll nuts.

not you August 31, 2019 - 1:22 PM


vio2112 December 16, 2019 - 11:59 PM

Well if they do exist, one thing I know for sure is we are not going to get the answer in a 3 minute YouTube video..

Felicity Halsey May 3, 2020 - 2:24 PM

There's no real evidence. If aliens do exist light speed would rip you apart. First off the elements to even create such a thing seems fictional.

Aliens and the UFO's are our modern counterpart to "Witches".
