Aliens exist and they live in our midst disguised as humans -- at least, that's what 20 percent of people polled in a global survey believe.

外星人不仅存在，而且假扮成人类生活在我们中间——至少有20%的人这么认为。

Wearing a hat shaped like a alien space craft, a man video tapes the arcade outside of the international UFO convention in Roswell, July 3.

The Reuters Ipsos poll of 23,000 adults in 22 countries showed that more than 40 percent of people from India and China believe that aliens walk among us disguised as（装扮成） humans, while those least likely to believe in this are from Belgium, Sweden and the Netherlands (8 percent each).

However, the majority of people polled, or 80 percent, don't believe aliens in our midst.

"It would appear that that there's a modest correlation²（相关，关联） between the most populated countries and those more likely to indicate there may be aliens disguised amongst them compared with those countries with the smaller populations," said John Wright, Senior Vice³ President of market research firm Ipsos.

"Maybe it's a simple case that in a less populated country you are more likely to know your next door neighbor better," he said.

More men than women -- 22 percent vs 17 percent -- believe that alien beings are on earth.

Most of those believers are under the age of 35, and across all income classes, the survey showed. Of those who do not believe, most are women.
