我们在宇宙中并不孤单——甚至可能在地球上也不孤单。至少公众是这么认为的。
大多数美国人认为其他行星上存在智慧生命，五分之一的人认为外星生命已经与我们取得了联系。
对于那些认为尚未发生接触的人来说，许多人预计未来某个时候会实现接触。
如果此类面对面的相遇真的在地球上演，美国人表示，他们会以更多的好奇而非恐惧来迎接外星访客，同时也会带着些许不安。
美国政府近期披露的UFO文件，让一些美国人认为我们早已被外星生命造访过。看过UFO文件中视频的人尤其持这种看法。
人们还怀疑还有更多真相有待揭露。十分之八的人认为政府掌握的UFO信息比它所披露的要多。
近年来，认为其他行星存在智慧生命的人群比例进一步扩大。仅回溯到2010年，相信这一点的美国人还不到一半。自那以后，更多男性、女性以及各个年龄段、不同教育水平的人群都开始相信智慧生命的存在。
人们表示，如果外星人来到地球，他们会对相遇一事感到更多好奇而非恐惧。但此类接触也会引发一些焦虑——感到紧张的人会多于保持平静的人。
你见过不明飞行物吗？
关于UFO是否造访过地球的争论仍在继续。
17%的美国人表示曾亲眼见过自己认为是UFO的物体。这与盖洛普民调近年的结果相似，但比该机构1970年代的调查结果要高。
称自己见过UFO的男性比例高于女性。
那些表示见过自认为是UFO物体的人，绝大多数都相信智慧生命的存在，且多数人在遇到此类生命时会感到好奇，同时许多人也表示会对这种可能性感到紧张和兴奋。
那么，它们到底是什么？
美国人在UFO报告的成因上存在分歧：一部分人认为有时是外星飞船造访地球，另一部分人则认为所有报告都源于地球人类活动或自然现象。
相信外星智慧生命存在的人，绝大多数认为UFO报告至少有时是外星飞船造访所致。但不相信外星智慧生命存在的人则认为，更合理的解释是人类活动或自然现象。
绝大多数美国人都听说或阅读过至少一些关于联邦政府披露的与不明异常现象（UAP，即俗称的不明飞行物UFO）相关的文件和视频，其中十分之四的人表示观看过披露的视频。
十分之三的人表示，这些材料让他们更相信外星人曾造访过地球，在看过视频的人群中，这一比例升至十分之四。
美国人仍认为美国政府有所隐瞒
绝大多数人认为政府没有公开其掌握的所有UFO相关信息。这一观点在相信外星生命存在的人群和不相信的人群中都占据主流。两党在这一问题上也达成了共识：大多数民主党人、共和党人和无党派人士都不认为政府向公众公开了其掌握的全部信息。
本次哥伦比亚广播公司/YouGov民调于2026年6月2日至4日期间进行，受访样本为具有全国代表性的2023名美国成年人。样本根据性别、年龄、种族、教育水平，参照美国人口普查局美国社区调查和当前人口调查数据，以及2024年总统选举投票结果进行了加权处理。本次民调的误差范围为±2.8个百分点。本文引用的哥伦比亚广播公司1997年、2010年、2017年和2021年的民调均通过电话进行。
CBS News poll finds most Americans believe extraterrestrial life exists – and some think it’s already here

We are not alone in space – and maybe not even on Earth. At least that’s what the public believes.
Most Americans believe intelligent life exists on other planets, and one in five think they’ve already made contact with us.
For those who don’t think that’s happened yet, many expect contact at some point in the future.
If such face-to-face encounters were to take place on Earth, Americans say they would greet the alien visitors with more fascination than fear, along with some unease.
The government’s recent release of UFO files has some Americans saying we’ve already been visited by extraterrestrial life. This is especially the case among those who have watched the videos in the UFO files.
And people suspect there’s still more to come. Eight in 10 think the government knows more about UFOs than it is telling.
The percentage who believe intelligent life exists on other planets has become more widespread in recent years. Looking back just to 2010, fewer than half of Americans believed that. Since that time, higher numbers of men, women and people across age groups and education levels now believe in the existence of intelligent life.
People say they would be more curious than scared about the prospect of meeting extraterrestrials should they come to Earth. But such contact also generates some anxiety — more would be nervous than calm.
Ever seen a UFO?
The debate about whether UFOs have visited Earth continues.
Seventeen percent of Americans report having personally seen something they thought was a UFO. This is similar to what Gallup polling has shown in recent years, but a higher percentage than what their polling found in the 1970s.
More men than women report having seen a UFO.
People who say they have seen what they believe was a UFO overwhelmingly think intelligent life exists, and most would be curious upon meeting such beings, with many also saying they would feel nervous and excited about the prospect.
So, what are they?
Americans are split on whether reports of UFOs might sometimes be caused by alien spacecrafts visiting Earth, or are always the result of human or natural activity that comes from Earth.
Those who believe intelligent life exists out there overwhelmingly think reports of UFOs are at least sometimes the result of alien spacecraft visiting. But those who don’t believe in intelligent life think the more likely explanation is human or natural activity.
Most Americans have heard or read at least something about the federal government’s release of files and videos related to Unidentified Anomalous Phenomena, or UAP, also known as Unidentified Flying Objects, and four in 10 report watching videos that were released.
Three in 10 say this material has made them more likely to believe that aliens visited Earth, a figure that rises to four in 10 among those who have watched videos.
Americans still think the U.S. government knows more.
A big majority says the government is not telling all it knows about UFOs. It’s the predominant opinion among those who believe in extraterrestrial life, as well as those who do not. And there is agreement across party lines on this: Most Democrats, Republicans and independents don’t think the government is telling the public all it knows.
