A lot has changed over the past 25 years . . . including Americans’ belief in EXTRATERRESTRIALS.

In a new poll, 57% of Americans say that aliens definitely or probably exist . . . compared to just 25% who DON’T believe in aliens.  The other 19% aren’t sure.

Back in 1996, a similar poll on UFOs found that just 20% of people believed that aliens were responsible for the supposed UFO sightings.  While a whopping 51% believed there was a natural scientific explanation.  29% weren’t sure.

7% of Americans believe we’ll “definitely” make contact with aliens within 10 years.  13% are confident it will happen within 50 years . . . and 26% say they know it will happen within 200 years, even if they’re not there to see it.

So what will the aliens be like?  44% of people say they’ll be “far more technologically advanced” than humans.  7% say they’ll be less advanced.  11% believe they’d come in peace . . . 9% believe they’d be hostile . . . and 4% say they’ll look just like they do in the movies . . . green with large heads and eyes.
