Well, there are real things that appear to be flying that couldn't be identified; that's why they're called UFOs (Unidentified Flying Objects). Some are later identified. There has never yet been actual proof that UFOs come from anywhere but earth.
UFOs are by their nature, impossible to prove. If they were proven, they would be identified and would cease to be UFOs.
No.
yes duhh
No, since UFOs have never been proven to exist, no highway is needed for landing.
They are myths. Theoretically it *is* possible but they are completely unconfirmed or proven.
Roswell Yes and Ufo's No
There is no confirmed evidence in favour of this.

everyone would panic!
Yes, they could be time machines because we haven't proven them to be anything definite yet.
Ufologist. Please note that "UFO" is not an acronym for "alien spacecraft". No UFO ever, has been proven to be an alien spacecraft. In fact, at this time the existence of aliens is not proven. They seem likely, but some race in the universe has to be the first, and we don't know that we aren't it.
President Obama has mostly deceived himself and the people who worship him, and he's strange enough without needing to involve UFOs.
