Technically, everyone should believe in UFOs for the simple following reason: Anything that flies and is unidentified by an onlooker, is by definition a UFO. This might range from an exotic breed of bird to a weather balloon, a Wi-Fi controlled quad-copter or a plastic bag pushed by winds. Basically it simply needs to comply to the following two rules:
-Does it fly? <-Yes
-Do You know what it is? <-No
It’s a UFO.
About 1/3 Americans believe aliens exist, which they obviously do, just not here on Earth. The poll shows something mind blowing though: If aliens invaded the Earth, 21% of Americans would call the Hulk in to defend, 12% would call Batman, and 8% would call Spider-Man.
I don’t know exactly how they plan on calling superheroes. Their numbers are notoriously unlisted.
Still to those people I have but one message: Do not worry about an alien invasion, they are not going to invade as long as we have Chuck Norris. Aliens do not invade Chuck Norris, Chuck Norris invades them.
