An advanced alien civilization visited the Earth in times long past. Proof of their presence in rock-carvings, religious artifacts, ancient myths, and, of course, megalithic monuments such as the Giza pyramids are littered all over the world. This video examines ancient ruins, lost cities, spaceports, and a myriad of hard scientific facts that point to extraterrestrial intervention in human history. Most incredible of all, however, is the theory theory that we are the descendants of these galactic pioneers—and the video reveals the archeological discoveries that prove it. Includes remarkable photos that document mankind's first contact with aliens at the dawn of civilization. Analysis of the evidence used by mainstream science anchor theology to explain the presence of artifacts, writings and other materials, coupled with his alternative explanations and proofs were not only plausible, but also down right convincing.
