I voted no, not because I believe that we're all alone in the universe, but because every "alien" that people have "seen" would be so incredibley improbable that they are almost definitely explainable in some other way. If there are sentient beings on other planets, the odds of any of them looking even remotely similar to any earthly creature are impossibley slim. Most likely they'd have originated from some entirely different system from us. The biggest organic element on our planet is carbon, and thus all life on earth is carbon-based. owever on another planet there may be elements that we've never even imagined. So my vote for no was not saying that I think there are no aliens out there, it was stating that any aliens that we think have come to earth, or actually, even anything we could imagine at all, would be like the aliens that really are out there.

if they exist they apparently fear me because i have never seen one and they've had plenty of chances when i'm alone in the woods at night.

i think people have dreams at night and wake up thinking its something that actually happened.

i've read the intelligent arguments on here but for me seeing is believing...

i say no. they do not exist.

Not only do I believe that alien life exists, I believe the theory that ancient civilization's "gods" were alien visitors that enlightened them in science, the arts, mathematics, and other technologies.

Take the egyptians for example. They built the pyramids, and the pyramids became one of the ancient wonders of the world, but even with modern technologies, it would take approx. 2-3 centuries to build them. In addition, the pyramids are lined up in a perfect line, which modern technology only recently has created a way that this could be done (GPS and SAT photography.)

It all may mean nothing, but I don't believe in that many things coming together without having a way to explain them.

I don't believe that for a second.

When we can make 100 story sky scrapers in a few months/years I find it extremely hard to believe that it would take 2-3 centuries to build. That can't possibly be correct.

Aliens must exist because there has to be intelligent life somewhere (because there certainly doesn't seem to be any on this planet )

It might not take 2-3 centuries but I think it would take longer to build the pyramids then the egyptians took to build them.
But in any case there's also the fact that we have construction equipment that they didn't have back then and our building materials are alot different to the huge stone slabs that the pyramids are made from.

yeah, but his assertion was that "even with modern technologies, it would take approx. 2-3 centuries to build them."

That is totally false.

You can't be serious. Do you really think that people didn't know how to make straight lines before GPS was created? First, they're not in a perfectly straight line. They're close enough to be called straight, but they're not perfect. Second, it's very easy to create an axis, you can just scrape out lines on the ground. It's not that difficult to align things like that. Look at the Romans.

I go with both. There are chances of find a planet with liquid water and has the right distance from the star it goes around. Why it is just in our minds because it would take a very long time to discover a another planet with life.

We will never know for sure.....
I'm leaning more towards it being just in our heads

I think that aliens are real. I may be a kid but, we can't be alone in this universe.

In my point of view, aliens are real.
Maybe they've visited earth in the past and tought people how to make some great monuments, such as pyramids. But when they left, the knowledge, that they gave us, was forgotten.
But that's only my opinion...
If they never show up and tell us the truth, we will never know for sure.

We can't be the only ones within the universe. That just doesn't make sense and kinda sounds selfish. Aliens gotta be real, now what they are is a mystery but there somewhere out there in the black place they call space? Space for what, theres plenty of things that fill it....

I do believe in nice aliens that can help us and make our lives better, maybe living outer our solar sytems, maybe even galaxies away.

Since the world, including the whole galaxy and solar system put togeter, there has to be maybe another human race in another planet, waiting.

I just can't force myself to believe that we're the only ones in the universe. If there's a God, then we know he's made more planets with people on them because it says that in Abraham. If there's no god, but still evolution, the chances of evolution not happening in this infinite universe anywhere but here is almost slimmer than the chances of it happening, in my mind. Maybe they aren't advanced enough to explore space, just like us, or maybe they are and they're watching us. Any civilization advanced enough to be able to travel through space and find our planet would be advanced enough to be undetectable by any of our observational devices. If they aren't advanced enough for space travel, and aren't flying around our planet, that doesn't mean that they don't exist.

Aliens like the way everyone seems to think of aliens is absurd.

First off, the only reason we have life here is because Earth is the perfect position away from the sun (a red giant) to support life. So first, we'd have to find a planet that is also the perfect distance away from a red giant to support life. And even if you do, the thought that aliens resembling humans is bogus too. Chances are, if you can find another form of life, it'd probably more look like a roach or a scorpion or something, but not human at all.

And if people honestly believe in UFO's, then let me ask you all this. How could UFO's exist on other planets if we ourselves (with all of our technological advances in even the last few years) can we even invent a working four-foot tall model or whatever? (just as an example) Why are we counting so much on "Oh, aliens are smarter than us and can invent stuff we can't" when, as I said earlier, that a human-shaped alien is absurd. Do you wanna know what invents machinery? Living, working, human fingers. Lol. NOT alien technology.

Sorry, people, but the thought of aliens like that are ridiculous...

I think the idea of aliens is primarily a bunch of made-up conspiracy theories that fed off one another. Most of the claims that have been made here in support of the existence of aliens seemed pretty invalid to me and more gut-feeling-based. I suppose that's all we can really give since we don't have many cold hard facts off which to base our beliefs, but I still believe they don't exist. I won't, however, refuse to acknowledge that they may exist.

I have learned a lot throughout my university studies, but I still have no set answer. I can only base my reasoning on facts that I've learned here and there. Let me just say that I am a firm believer in science. Now, we live on what is basically an ideal planet. If the Earth's temperature, pressure, and other properties were different, it would become uninhabitable. Even our position in the solar system, the shape of our axis, and the angle of tilt (for Earth's rotation) affect our capabilities to live on Earth. The list of ideal variables is endless, really (gravity is just right, our atmosphere is perfect, etc). In other words, I am saying that a world as fine-tuned and "perfect" as this is next to impossible to create. Does that deny that there may be another "perfect" (inhabitable) world out there? Or does that deny that there may be other intelligent lifeforms out there that exist without these ideal conditions? No. Like I said, I won't deny that they may exist. In general, however, I don't believe they do.
