A look at ancient astronaut theory.
Believers of ancient astronaut theory like Erich Von Daniken, author of the popular book, Chariots of the Gods, and Zecharia Sitchin, author of many books on the subject, both maintain that historical gaps and unexplained archaeological records can't dismiss the fact that ancient civilization was far advanced in technical culture and aware of strange flying craft above their heads. These ancient people were also aware of the Gods or super-beings who that flew these air ships, descending from the heavens and sharing wisdom.
Zecharia Sitchin's book The 12th Planet claims the Sumerians (ancient inhabitants of southern Mesopotamia in 4000 BC) believed the Anunnaki visited the Earth 400,000 years ago and interfered with human evolution, with the Sumerians in fact to create royal offspring. The idea of ancient astronauts have played an incredible part in human mythology and archaeological discoveries. Clearly ancient humans believed in mysterious Gods and highly intelligent beings visiting our world.
Every known culture today like Japan, America, India, Europe, Middle East, and from the past like the Greeks, the Romans, Mesopotamians and ancient Indians; have recorded in their history encountering Gods sent to influence or instruct the chosen people with secret knowledge and ideology. Evidence shows that these gods arrived from heaven in chariots of fire or air-ships, much like what we would call UFO's today.
In Val Camonica, Italy, the ancient inhabitants who lived in the valley from the Neolithic
Period had left approximately 300,000 petroglyphs (rock carvings) of daily life dating back to 8,000 BC. Some petroglyphs illustrate strange beings floating with helmet-like gear on and this same type of rock carving can be seen all over the planet. Often legends and myth tell of strangers arriving in awesome ships of light or magical-power and resemble some of the same characteristics associated with close encounter of extraterrestrial beings.
Another interesting unexplainable clue is the Peruvian Nazca lines. From the air the lines (geoglyphs) appear like ancient runways and depicts huge figures that can only be identified in an airplane. Ancient astronaut theorist believe these God-like beings for whatever reason wanted to excel the primitive homo sapiens to a higher level of intelligence. Many ancient cultures postulate this idea that their gods created them and manipulated their race. The theorist further proclaim this fact as true, to help explain the sudden rise in human evolution over the past 200,000 years.
The most common belief is that humans are created in God's image and this concept isn't strange or new to us. This belief is ancient and connects us with God. But the ancient astronaut theory goes even further and states a much more common fear we face today: genetic manipulation.
Homo sapiens abruptly spring boarded forward on a evolutionary scale is well known in the scientific community. It is a strange fact but true nevertheless. But only today, in modern times, with our complete understanding of genetic engineering that we discover that it is possible to alter, manipulate, and control on a genetic level almost any living thing on the Earth. This could be extremely helpful in medical treatments and also highly unethical to alter nature. As a society we have just begun to fully comprehend how to manipulate DNA (Deoxyribonucleic acid), a thought unheard of a century ago and only in the pages of science fiction novels. But the mere fact that most ancient cultures who encountered direct contact with their holy-deities, already knew about the genetic intervention done to them by these supernatural beings.
