Summary: Millions of people around the world believe we have been visited in the past by extraterrestrial beings. What if it were true? This is the question Ancient Astronaut theorists have posed since Erich von Daniken’s Chariots of the Gods was first published in 1968; examining scientific, archaeological, astronomical, and historical evidence to find the answer. In recent years, more new evidence has been revealed than ever before that suggests there was extraterrestrial intervention on Earth in the distant past. Satellite images have exposed geoglyphs resembling Nazca lines in Kazakhstan. Ground penetrating radar has detected remnants of ancient technology in Machu Picchu. And thermal scanning has uncovered hidden chambers behind King Tut’s tomb that may hold the remains of extraterrestrial beings. Could we be at the tipping point where the overwhelming evidence outweighs any last shred of doubt?
