There is a popular belief that aliens walked the Earth in ancient times, and these theories have created quite a stir in the scientific community. Ancient alien theorists, such as Erich von Daniken and Zecharia Sitchin, believe that extraterrestrials came to earth thousands of years ago. Some speculate that ancient aliens are responsible for ancient technological marvels and helped shape human civilization. Furthermore, there is a widespread belief that the ancient gods were actually aliens, misinterpreted as gods by the ancients. As it turns out, there's quite a bit of evidence to support some of these ancient alien theories. However, everything is subject to interpretation, as it has not been validated. The evidence used to support the ancient alien theory can be found around the world in ancient geoglyphs, art, sculptures, architecture, and texts. A fascinating subject that has captivated millions of people, Ancient Aliens revives the possibility that we are not alone in the cosmos and gives us a new perspective on the life that exists beyond our planet by looking at our past history and civilizations. Erich Von Daniken, one of the main figures responsible for popularizing the hypotheses of ancient astronauts, wrote twenty-six books referring to his theories about ancient aliens. Von Daniken's examination of ancient texts, archaeology, works of art, and other wonders are the basis of his theories of extraterrestrial intervention in human history. Von Daniken argues that myths, arts, science, astronomy, architecture, etc. ancient cultures were introduced by astronauts from another world. It also suggests that some deities from our ancient history, such as Rama of India and Ra of ancient Egypt, were alien astronauts who... middle of paper... searched for radioactive elements to find levels at least 50 times higher than that would be considered natural radioactivity. Could this be evidence of an ancient nuclear war in Mohenjo-Daro? Ancient astronaut theorists believe it is. Works Cited Cox, Billy. "Interview with Erich Von Daniken." Florida today. 1996.
