More than a third of people in the U.S. believe aliens exist – and more than 10 per cent of the population believes they have seen an alien ship in the sky.
The study from National Geographic Channel found that 80 million Americans – or 36 per cent – are certain alien spaceship exist, and of those who believe, 79 per cent are convinced the White House has kept information about other lifeforms a secret.
If an alien knocked on the door, 22 per cent would try to befriend the alien, 15 per cent would run away, 13 per cent would lock their doors, and, reassuringly, only 2 per cent would try to inflict bodily harm.
