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.
There is no reason to think so. So far, there is no actual hard evidence that aliens actually exist.
Aliens are not known and proven to even exist, let alone be here and harming people.
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.
Nothing. There are no aliens known to exist.
If space aliens do indeed exist, they exist for the same reasons we exist. Whatver those reasons may be.
There is no evidence that aliens exist therefore the biology of aliens, if they do, is unknown
No
I can answer that for you...Aliens don't now nor have they ever existed. God created the human race in his image, and he did not create any other race, but us. ___ Perhaps they do exist. Who's to say whether they do or not. If they don't exist, the universe will be a lot lonelier.
aliens, Might exist but their are rumours that they probe people.
its not that u are cray if u think aliens exist ,if someone says the exist and someone says they dont exist , just respect there answers
If we were there, we would be aliens. If they were here, they would be the aliens. Depends on the type of alien.
I don't think they eat anything. You have to exist to need food, and no aliens are as yet known to exist.
