WASHINGTON (CIRCA) According to Space.com, there are roughly between 100 billion and 200 billion galaxies in the universe. And yet, we only have definitive proof of life on Earth.

That doesn’t stop many Americans from believing there’s life on another planet.

“Thirty-seven percent of Americans, nearly four out of 10, say it’s very likely there’s life somewhere else in the galaxy,” said polling and data expert Scott Rasmussen.

“Twenty-two percent believe it’s very likely that at some point in the past, lifeforms from other planets have visited the Earth,” he said. “And one out of nine, 11 percent, believes that some people from other planets are living on Earth today.”

Some Americans take things one step further. Beyond believing in life on another planet, some people are ready to punch a hole in the space-time continuum.

“Nine percent, one out of 11 people, believe that time travel is possible,” said Rasmussen.

“Eight percent believe it’s even possible someone from the future is living with us here today.”
