Because we are stupid...
There is no proof that aliens exist. I believe there is no such thing as aliens. Has anyone seen an alien ship? Has anyone seen an alien? No.
Its completely up to you to believe if aliens exist. There is no proof that they are real, but then again we don't know. hope it helped? xx
I believe aliens might exist somewhere in the universe, but I don't believe any stories about UFOs or abductions or crop circles or anything like that. -------------------------------------------- A good answer. I don't *believe* in aliens because I have seen no proof of them, and belief without proof is faith (religion) not science.
there is no definite proof but aliens are likely to exist
There is no solid proof aliens even exist much less have visited Earth.
Do they "exist"? Probably. . . I've never seen ACTUAL proof.
There have been many people who claim to have witnessed both UFOs and aliens, however there is no proof available to the general public. If proof does indeed exist, it is held as confidential information by the government.
It's fun to pretend, but there is no proof and so there is no good reason to believe this. The universe is really big but that does not prove that aliens exist. After all, someone in the universe has to be the first, and there is no solid proof it isn't us. Aliens are real because we can't be the only life in the hole of the universe and some people think there are labs holding aliens.
I look for all the (living or dead) aliens there are, lying around as proof. Then I look at all the transhuman hardware lying around. And since I never see anything, I conclude there is no evidence that aliens exist.
It is a proven fact that invisibility can be achieved through bending light around an object, acting as a cloak. So if aliens exist and have the technology to prove it, then yes they will be able to *POOF* stupid old answer - No body actually knows because there hasn't actually even been proof that aliens even exist! Depends on the alien
There is no proof that aliens exist. If they do, they may have eight arms.
If you mean aliens from another country, yes. If you mean aliens from space... not that anyone knows and has been able to prove. No proof aliens even exist, in real life. Just tall tales.
