Do you think that Extra-Terrestrials (aliens) exist? And do you think they have ever visited our planet?

Question

I certainly think that they're out there in one form or another.

Many people say they have visited Earth. And so many alien landing stories also rely on having us believe that our governments would want to hide such a thing from the general public. Personally, I think if aliens had ever visited Earth it would be common knowledge by now. It would be in all our school history textbooks.

What do you think?

Answer 1

No, that stuff lies in the realm of pseudoscience.

Aliens, UFOs, and similar claims are largely the work of kooks.

Now get groovy with some real evidence yeah baby yeah.

Answer 2

As that guy from Monty Python once said "I have to believe there is intelligent life out there somewhere, 'cause there sure isn't a h**l of a lot of it on Earth!"

I do believe they're out there, the universe is gigantic, and for us to think that we are the only beings with higher intelligence, is arrogant. No I don't believe they have visited.  If there really is remanance of a space-shuttle and an 'alien' in Roswell, well I would have to see it with my own eyes, even then I wouldn't believe it, I would have to conduct tests on the 'alien' with my own two hands to determine whether it is a fake or not.

Answer 3

There is no evidence one way or the other about whether life exists on other planets. It seems likely, but that is only speculation. We may never know. I am certain that IF any exist, they have not been here. All we have are misidentified normal items, crude hoaxes and delusion of mentally ill people.  

Answer 4

Yes and no.  They probably exist.  They haven't visited Earth.

Governments might hide such a thing in the interests of national security.  But that might happen if perhaps some weapons could be made out of alien technology.

However, the alternate explanations of the millions of UFO and alien abduction reports is more plausible.  Mass hallucination.

Answer 5

im sure there are aliens somewhere because there is an almost infinite number of planets in the universe so there has to be right conditions on one of them. and im not sure if they have visited earth but im kindof convinced by that dude who set up a video camera in colorado in one of the second story windows thinking there was a peeping tom spying on his daughter and that in the video a white round head with big black eyes kept popping in and out they havent released the video yet to the public but peole who have looked at it so far haven't been able to find any way of it being photoshopped or edited

Answer 6

Well, I know a lot about astronomy, because I am "studying" it as a hobby since I was a child.

And, just as you, I am absolutely sure, that there is more life out there. And I'm absolutely sure as well, that it NEVER has visited us and it probably never will either. People who claim that, may have a very "wild" phantasy, but only a very bad understanding of mathematics and astronomical proportions.

First, why there has to be more life:

We live in a solar system that consists 9 planets in total. On EACH of those other 8 planets (except the earth) could be some life - theoretically. But as we know, the living conditions aren't very nice there, and life therefore doesn't exist. So, let's just go some further "out".

Our Sun is a star. One only star out of hundreds of billions of stars. Each of those billions of stars is - at the same time - the sun of a solar system. Most of this systems contain planets. Some less than our one does, some more. All these billions of stars and planets together are one galaxy: the milky way, our galaxy.

But there ain't only one galaxy, there are billions of billions of galaxies out there. And EACH of these galaxies contain billions of solar systems (with planets)!! And we, human beings, only know an extremely small part of all that stuff, that's out there.

It's sorta like this: Picture yourself walking along a very large beach. And as you dig your hand into the sand besides your feet, the grains of sand in your hand represent the galaxies, the solar systems and stars and planets we know. But let's lift our head again and face the rest of the beach. What is it? It's hundreds of tons of sand, hundreds of yards of plain sand. This is the astronomical proportion. The size of the part of our universe, which we DON'T know.

With other words:

The mathematical chance, that there isn't any other life out there is like winning 10 times in a row the lotto-jackpot. Does this sound probable?

Now, the seond thing is, if this life has ever visited us.

Here we go:

Just as above, here we have to deal with the unbelievable size of our universe as well. And with it's distances. Some people say, that this Aliens don't have problems, to come to us, because they are more developed and intelligent than we are. Well, that might be! It really could be possible. BUT it doesn't matter! Because even IF these aliens are way more intelligent, they STILL have to accept and live with the mathematical rules of our universe! They aren't god either, so they can't just change these rules! As we know, if we only want to travel to the next star (the closest one to our sun), we need 5 years. IF we travel with the speed of light. But it isn't possible for any form of life to do this. There is NO way to survive this (you basically would get torn into thousands of little pieces). So, we have to surmise, that this journey would take even MUCH longer! Maybe it would take hundreds or thousands of years! And even if we get there, you have to see, that with the proportions in our universe, travelling to our next star is absolutely nothing. It's like the distance a bacterium walks at a day compared with the distance between the U.S. and India for example.

The distances and proportions in our universe are just TOO big, for that Aliens could visit us or we could visit them. I know, it's kinda sad, but that's how it works.

People who believe different are dreamers.

Answer 7

I think you need some form of proof.

If you are going to rely on 'stories' as proof, then the topic belongs under paranormal phenomena which probably is the category that this question should have been posted under - paranormal phenomena relies on the person hearing the story to believe or not believe based upon whether he thinks the story teller is telling the truth. There is no other proof to go on. We find this in ghosts, bigfoot, the Loch Ness monster, Atlantis, the Bermuda Triangle and other subjects like UFOs and aliens. You can find this category under Science and Mathematics-Alternative.

Answer 8

Of course they are real, and of course they have been to earth.

I'm sitting right next to one right now, smokin a blunt and kickin back a 40...

oh, yeah!  And Elivis isn't dead either!  And there really were weapons of mass destruction!....

What a putz!!
