Probably. If they can go from there planet to here.
It has not been determined. They could have had civilizations much longer than us, so it isn't easy to tell.
There are far more things to worry about in life than aliens attacking us. The chances of which are as close to zero as you can get.
So far, no scientist has been able to prove there even are any aliens, let alone intelligent ones. Someone has to be the first form of intelligent life, and it may well be us. Stephen Hawking says the Universe is so large that it would be nearly impossible for aliens not to exist. And scientist do not by any means think all aliens are intelligent. Hawking says most aliens are probably single-cell organisms. But if aliens ever manage to fly to Earth, they probably ARE pretty intelligent.
There are no aliens known to exist, in real life. Sorry. Someone has to be the first form of intelligent life in the universe, and it might well be us.
No. Since aliens do not appear to actually exist (somebody has to be the first form of intelligent life in the Universe, no reason to think it is not us), they cannot be gotten to do anything.
If by 'aliens' you mean intelligent extra-terrestrial beings, there is no plausible evidence that any have ever visited Earth. However, with billions of planets in the universe, it would be arrogant of us to believe that we are alone, as the only intelligent life forms that ever evolved. There must be 'aliens' out there.
No reason to think so. No reason to think there are aliens. Someone has to be the first form of intelligent life in the universe and it may be us.
It could become more intelligent than us....
Since aliens do not appear to actually exist, and are probably not criminals if they do exist, there is no way. Someone has to be the first form of intelligent life in the universe, and there is no reason to think it is not us.
Well assuming there are other intelligent living creatures in the universe, they would refer to other intelligent living creatures in the universe (which can be us) as a word in their language that has the same meaning as aliens. So, yes, for other intelligent living creatures in the universe. But that doesn't mean if we didn't live on a planet we wouldn't be aliens. Because we would still be other intelligent living creatures in the universe for other intelligent living creatures in the universe. And yes, I used copy/paste for other intelligent living creatures in the universe. :) By the way, you refer to humans as "them". Doesn't that make you and alien for us? :P
As many as you care to imagine. Aliens appear to be purely imaginary. Someone has to be the first form of intelligent life, it may well be us. ------------------------------------------- 51 nnnnnoooooooooooobbbbbb
There is no need to worry; in real life there is no evidence, let alone proof, that there are any aliens. Someone has to be the first form of intelligent life in the universe, and there is no reason to believe it isn't us.
if they are more advanced than us and if they exist then most likely but it is hard to know for sure.
