Whether though popular culture, or some kind of mass delusion, many people believe they have been abducted by aliens. Universe Today is a science-based website, and our position is that there is no reliable evidence to show that any kind of alien visitation or abduction has ever happened. There’s no physical evidence or proof, and until that turns up, we have to assume there’s a simpler, more logical reason to explain why people believe they have been abducted by aliens.
Alien abduction stories are similar. People remember being taken against their will by alien entities, and moved to some kind of spacecraft. In many cases they’re held prisoner, while their abductors perform medical experiments. And then they’re released, returned to their home with only their memories of the event, and no hard evidence to back up their story.
The aliens doing the abductions are similar to popular culture aliens seen in science fiction. They can appear as grey aliens with large heads (the greys), or Nordic-looking humans, reptilians, or beings of pure energy.
If the cause isn’t actual alien abduction, what’s going on here? Scientists and health professionals have many explanations: hallucinations, sleep disorders, mental disease, and sometimes they’re just making stuff up. Stories of abduction have been around for hundreds of years, but the nature of the stories have changed depending on popular culture. Long ago, it was demons, not aliens, where were abducting humans and performing experiments on them.
There are several programs looking for evidence of actual aliens. The SETI program (or Search for Extraterrestrial Intelligence) is scanning the skies, looking for evidence of alien radio signals. And powerful telescopes are now under development that may be able to detect the evidence of an alien civilization through how it pollutes its atmosphere.
In case you’re worried about getting abducted by aliens, you can actually purchase alien abduction insurance from several companies around the world. Of course, it’s up to the policy holder to actually prove they were abducted.
