SINGAPORE (Reuters) – 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.

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 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.
