Evidences in Ancient monuments
(6) The Great Pyramid of Giza in Egypt and many other colossal monuments of the ancient era are examples of engineering and construction skills which are too good to be developed or possessed by ancient man.There are many evidences which point to the fact that these megalithic monuments were constructed under the influence and guidance of extraterrestrial intelligence, which man had gained from the visiting aliens.
(7) The series of giant lines that are drawn on the deserts of Peru are an example of extraterrestrial activities on the planet. Drawing such accurately straight lines that would extend over miles was certainly not possible by the ancient man. Hence, these lines, which the world knows as the Nazca lines, are believed to be drawn by aliens while they visited the planet thousands of years ago.
Evidences in different civilizations
(8) The mentioning of Sumerian Gods in the Sumerian texts reveals that the Sumerians were being used by the Gods to harvest the land. These Gods are nothing but extraterrestrials that not only used mankind to carry out different activities but also enlightened them with the knowledge of mathematics and astronomy which the ancient Sumerians are believed to have developed about 6,000 years back.
(9) The Mayan civilization has many instances and evidences that prove the visiting of aliens to Earth. One of the most prominent evidences is the carvings on the lid of the sarcophagus of Mayan Emperor Pacal. On the carving, Pacal is seen sitting in some kind of an aircraft with his foot on a pedal looking object and his hands fiddling with some controls. This carving shows that the Mayans were certainly being enlightened with the knowledge of science and technology by the aliens who had visited the Earth thousands of years ago.
Firsthand accounts of people who have been abducted by aliens
