Throughout history, some people have claimed experiences that are the supposed results of alien visitation. While some of the factors of extraterrestrial visits range in variety, the basic structure stays the same, motivating further research into the topic.
Alien visitation refers to an intentional encounter between an extraterrestrial being to a human. For alien visitation to be considered a real issue among researchers, extraterrestrials must be proven to have a valid motivation for visiting, and the encounter must be scientifically possible and probable. As of now, theories have been put forth by various researchers regarding the validity of alien visitation.
The proposed motives for extraterrestrial visitations can be classified into three subsections: 1) attempt to influence the future of humanity, 2) attempt to warn or enlighten, and 3) experimental use.
According to ancient astronaut hypothesis, extraterrestrials had been active in the affairs of early man. Furthermore, Erich Von Däniken, a notable ancient astronaut believer, considers that the deities of ancient cultures were attempts at explaining alien visitation. Because Von Däniken’s hypothesis is considered purely speculative, the ancient astronaut hypothesis has no support within the scientific community. According to ancient astronaut devotees, proof of alien visitations in antiquity are found prevalently in patterns of art, technology, and engineering. To them, the Moai statues on Easter Island, the Pyramids of Egypt, and Stonehenge can all be easily explained through the ancient astronaut hypothesis. They also argue that the technological advances in antiquity are the result of alien visitation, citing unaccounted for invention and abnormal historical surges in technology as proof for their claims. The ancient astronaut hypothesis suggests that the motive for alien visitation is to influence the future of mankind. In fact, some ancient astronaut proponents even mention the cause of World War II and the atomic bomb as effects of alien visitation and activity. Although mainstream science and historians dismiss these claims as make believe, they do provide ample motive for a supposed alien visitation.
