What on Earth?!

Most Americans believe that aliens exist — and more than one in five think they’ve already paid our planet a visit, according to an out-of-this world new poll.

Some 63% of Americans said they’re convinced there’s intelligent life outside of Earth, a CBS survey of more than 2,000 people found.

Asked when they think humans will have contact with extraterrestrials, an eye-popping 21% said, “We already have,” according to the poll, taken earlier this month.

If a close encounter were to take place, most Americans said they’d greet aliens with more fascination than fear.

Roughly 67% said they’d feel “curious” about meeting extraterrestrials, while 31% said they’d be “scared.”

The alien-friendly response comes shortly after the Trump administration’s release of UFO files last month, which true believers say is proof we’ve already been contacted by alien life. 

A total of 84% respondents also said they think the federal government “knows more than it’s telling” us about UFOs, according to the poll.

Three in 10 people, meanwhile, said the UFO document dump made them more likely to believe that aliens have visited Earth.

Overall, 17% of Americans report having personally seen something they believe was a UFO, according to the poll.
