Aliens have popped up in human history since ancient times. “Thousands of years ago, extraterrestrials landed on Earth, where they were hailed as gods and helped shape human civilization,” said Erich von Däniken, a controversial author whose most famous work explores the influence of aliens on human culture. Some people say places like Peru’s Nazca Desert, the giant human figures of Easter Island and the giant carvings of Puma Punku in the Bolivian highlands are evidence of this inhabitation. Others point to the Book of Ezekiel and Sanskrit epics for evidence of flying vessels.
In more modern times, alien encounters are believed to occur most frequently on desolate spots away from civilization. One of the most famous cases of alleged abduction took place in New Hampshire on Sept. 16, 1961. In “Mysteries of Alien Visitors and Abductions” by Kathryn Walker, Betty and Barney Hill claimed they were abducted on a lonely road in the White Mountains. Under hypnosis, they revealed that aliens had conducted medical tests for two hours, only to erase their memories of this experience.
