Because they want to eat our brains! just kidding!! Actually there have been citings but they havent seen any landing space ships, unless they did and didnt tell the news. And i dont know the real reason why and if they are on earth but you can nvr know.
There is no reason to think so. So far, there is no actual hard evidence that aliens actually exist.
I would hope we would try to greet them as friends until proven otherwise. The fact is that if aliens have the technology to come to earth, I don't think we would have much hope of winning a war with them.
There is no solid proof aliens even exist much less have visited Earth.
No. Do you really think God would let aliens come here when we have our hands full with ourselves!
No, there are no aliens coming to the Earth or anybody's home.
probably
NO
If you got to Neptune and survived you would find aliens. The aliens would make you their slave and make you tell them the Earths military secrets. then they would come destroy the earth.
"Close Encounters of the Third Kind" is a movie from 1978. In real life, there is no reason to think there are any aliens, let alone aliens that come to Earth for any reason.
No evidence says so.
Aliens will come to earth one day. i know it. in the bible, Qur'an and other holy books all say that when the end of the world is near then aliens from basically all over space will come to earth and they will keep our earth going but us humans would go extinct from the aliens and they will be the things living on earth instead of humans. Its just like the dinasours, we took over and they went extinct. The same thing will happen to us.
No. What makes you think that aliens need doors?
