Another reason why theorists strongly believe that earth was visited by extraterrestrial visitors is the presence of certain elaborate and precise megastructures, which possibly could not have been created by man as he did not have the necessary tools in those days. For eg, the Pyramids of Egypt, Moai Stone of Easter Island, Balbek in Lebanon and Machu Pichu and Nazca Lines in Peru were so scientifically sound that theorists believe ancient astronauts visited earth and gave man the technical knowledge and special tools to build these vast structures. These monuments are large and can be best appreciated if seen from above. This further boosts their belief that perhaps these structures were like a landmark or an indicator to the alien astronauts to show where they should land their spaceship or served as a lift off pad.
In fact, there are many ancient texts like the Indian epics Ramayana and the Mahabharata, where gods, sages and kings could travel from one place to another in flying machines or “vimanas”. There is also mention of battle scenes where the descriptions are eerily similar to the use of nuclear weapons, something unthinkable in such an age.
Harold T Wilkins, Erich von Daniken and David Childress, among many others, believe these texts prove there were powerful beings that provided man with the advanced technology, and the only place they could have come from was outer space. These theorists still continue looking for answers behind the mysteries of Ancient Astronauts and how they affected the development of human civilisation.
