Does aliens exit

Answer 1

Scientists have found underground caves on earth that have about the same conditions as mars and have found microscopic life forms in these caves, and as humans we had to have started as (protists) one celled creatures believed to live mostly in water so my opinion is how can Earth be the only planet that sustains life forms that we know of.

But there is, as yet, no firm scientific proof. After all, someone must be the first form of intelligent life in the universe; it may well be us.

I believe there are. What's the point of having the other planets if nothing goes on on them? Everyone has their own opinions though, there had been many claims of alien sightings such as mysterious crop circles appearing at night in Europe.

The universe is a huge place.

However, this does not mean aliens are flying around making weird designs in cornfields or flying saucer shaped space vehicles, or even abducting people.

Life most likely does exist in other parts of the universe, however.

We have no evidence of intelligent beings from other planets who have visited the Earth, movies like "ET" and "Independence Day" notwithstanding.

However, "absence of evidence is not evidence of absence". The fact that we cannot prove that "aliens" exist does not mean that we can prove that "aliens" DO NOT exist. The "U" in "UFO" stands for "UNIDENTIFIED". If there's a strange light in the sky, we don't know what it is.

As much as the little kid in me would like to believe in Martians and aliens in flying saucers, the scientist in me knows that it would be extraordinarily unlikely that they have ever visited Earth.

I think there are. But nobody knows for sure. Why would we be the only living things in our universe?

Actually, scientists don't know yet if there is aliens out there. The Hubble telescope can see really far away that doesn't mean that there isn't aliens out there. I believe that there is aliens out there.

So far, aliens from another world are still a fantasy. Human imagination is a powerful tool that helps us with so many things in our real world. It can be interesting and fun to use your imagination to create, solve problems, and imagine what could be. Until there are facts to support alien life forms that are from outer space, there is nothing wrong with the fantasy as long as you know where it separates from reality.

Answer 2

there is no sure proof that they exist though i know they are out there because one time i was riding in the car with my dad and i looked out the window and there was this weird black huge UFO thing flying across the sky. i pointed at it and showed my dad and we both saw it.

Answer 3

There is absolutely no scientific proof of aliens anywhere, let alone among us.

Answer 4

Of course there are. But they are not flitting around in spaceships abducting humans.

Answer 5

If you mean 'Are there other advanced creatures out there somewhere?' the answer is probably yes. There is practically no evidence that any have visited our solar system.

Answer 6

Sure, both legal and illegal (extraterrestial alients, since they wouldn't have government permission, would also fall into this category)

Answer 7

There is currently no concrete evidence to suggest that aliens exist. However, the vastness of the universe makes it possible that there may be other forms of life beyond Earth.
