For the last few weeks, the imminent release of a U.S. intelligence report on unidentified flying objects (UFOs) had stirred excitement across the United States. So it's not surprising to find that most Americans believe in intelligent life inhabiting other worlds, according to a survey conducted before the report was made public on June 25.

Approximately 65% of Americans concur that extraterrestrials exist, and about 51% say that UFO sightings reported by members of the U.S. military represent visits from intelligent aliens, according to a survey conducted by the Pew Research Center, a nonpartisan think tank in Washington, D.C.

Pew released their survey results prior to World UFO Day, an informal holiday celebrated on July 2 by UFO enthusiasts. The date is a nod to the purported 1947 UFO crash on a ranch at Roswell, New Mexico, according to the World UFO Day website. While the exact date of the alleged Roswell crash is unknown, the U.S. Army issued a press release on July 8, 1947, describing the recovery of a crashed flying disk from the ranch, launching an enduring fascination in the U.S. with extraterrestrials and UFOs (army representatives later identified the mysterious object as an errant weather balloon).

For the survey, Pew representatives questioned 10,417 American adults about aliens and UFOs. They found that about 76% of people between 18 and 29 years of age were likely to believe in intelligent aliens, compared with 69% of people ages 30 to 49 and only 58% of people ages 50 to 64. Regardless of age, most people who were surveyed — 87% — rejected the notion that UFOs posed a threat to national security — although the question didn't break down whether that's because they believe UFOs are ordinary objects or because they believe the aliens flying these UFOs are friendly.

The long-awaited government report on UFOs was promised to the U.S. Senate Intelligence Committee six months ago. The committee requested an investigation into unidentified aerial phenomena (UAPs), to be delivered by the the director of national intelligence and the secretary of defense, at a time no more than 180 days from Dec. 21, 2020 — the date when the Intelligence Authorization Act for the Fiscal Year 2021 was enacted.

While Pentagon officials released most of the new report, part of it remains classified and is not available to the public, Live Science previously reported. However, the report did reveal that military aviators recorded 144 UAP sightings between 2004 and 2021, of which only one could be definitively identified — as a weather balloon, the report said.

The report did not describe any UAPs as extraterrestrial in origin, instead saying "there are probably multiple types of UAP requiring different explanations based on the range of appearances and behaviors described in the available reporting."
