Question

Are there really aliens from other planets?

Answer 1

Yes, I believe so.
Quote from Carl Sagan
"If we are alone in the universe, it will be an awful waste of space."

The bigger question is, will we recognize them when we find it. Most fictional aliens are directing us (and thereby limiting our imagination) that aliens are like us with torso, head and limbs. Aliens may not even be a carbon life form.

Answer 2

There are vast numbers of stars in the universe, and some argue that this means that there must be other beings because no matter how unlikely it is for beings to arise, the sheer number of stars means that they must exist elsewhere as well as here.

However, if the numbers are such that the nearest beings are so far away that we cannot reach them to know of their existence and they cannot reach us to know of ours, then essentially they don't exist.

Also ask yourself this: If they are advanced enough to travel the enormous distances between stars, would they bother with a civilisation like ours, which has barely left it's home planet? Wouldn't they seek out others on their own level of advancement?

Considering all this I'd say effectively no, there are no aliens, at least not that we'll ever learn of until we go seeking for them ourselves.

Answer 3

Well, my first question to you would be, "Do you mean that there are aliens FROM other planets here on Earth?" or do you mean "Are there really aliens ON other planets?"

If you want to know if there are aliens from other planets here on earth, I would say it is doubtful. People always joke about how UFO sitings are usually in back-woods "hick" areas but if you think about it, if YOU were going to go on a recon mission to someplace, even if it was somewhere like Paris or London, would you really land right in downtown. No, you would land in a remote area an sneak in. That being said, I still don't think there are any here on earth right now.

Now, if you want to know if aliens exist SOMEWHERE else in the universe, I would say sure, statistically the odds are there is. Of the billions of galaxies and the billions of stars in each of those galaxies and those billions of stars having planets, what makes us (earth) SO special? Those aliens may or may not be of what we call "intelligent" but that does not mean there is not some sort of living species out there.

Answer 4

Considering the number of galaxies, the number of stars in each galaxy, and such, there have to be many other planets out there...some of which are going to support life. Many are farther out, and-if you believe in evolution-have evolved longer than us, and so are more advanced, and so life does exist on some. If you believe in creation, why would God create so many suns, worlds, etc, and then put life on only one? He wouldn't. So, there are more life forms out there somewhere. No matter how you look at it, the odds say there are other planets with intelligent life forms on them..space aliens as far as we are concerned. Most are too intelligent to come here, however.

Answer 5

Well...

Are there any aliens we know of? No.

It is unknown if they exist at all, though. Statistically, it is pretty likely that there are at least some somewhere. Even so, most systems cannot support life; the conditions necessary are extremely rare (right size sun, suitable planet the right distance from it, no nasty objects like magnetars nearby, etc). I personally think that they do exist, but we won't find them for a long time, if ever.

Answer 6

There is no evidence that there are life on space but maybe there is the universe is very big there somethings that science cant explain universe is made up of billions of small planets and stars.

Answer 7

Unknown.
There is no scientific evidence or proof of any kind to lend credence to the idea of aliens on or from other planets.
Doesn't mean they don't exist, it just means we have no proof that they exist. The videos, "eye witness accounts", stories, and myths are all hearsay and none are verified by independant scientific investigation.

Answer 8

There is absolutely no evidence of life on other planets so an outright "yes" is unjustified. I would say more unlikely than likely but its almost certain if there were that we would never know.

Answer 9

no we do not have evidence if we did we would invade there planet

Answer 10

absolutely, without question
