There are large beliefs that we were visited by alien beings thousands of years ago. Possibly teaching use how to farm, and where to go. Then even probably made it possible for us to hold tools. This is one of the greatest mysteries of Humanity. It even manipulated large religions like Christianity, and other cultures like China.
Some amazing stuff:(Probably not true)
Dr. Tsum Um Nui , in 1962, painstakingly transcribed the characters from the disk to paper. The writing was so small he had to use a magnifying glass to see it clearly. But the stones were old - perhaps 12,000 years old, it was estimated - and much of the hieroglyphics were difficult to make out or had been worn away by time and the elements. As he worked, many questions nagged the professor. How did these primitive people fashion these precise stones? How did they manage the almost microscopic writing? Who were they and what was the purpose of these hundreds of stones? Once the characters were transcribed, Dr. Tsum Um Nui began the arduous task of trying to decode its message. Eventually, he began to make progress. A word emerged. Then another. A phrase became understandable, then an entire sentence. He had broken the code. He discerned that the messages on the stones were written by a people who called themselves the Dropa. But what they were saying to him 12,000 years later made no sense. What the Dropa had written must have been one of their cultural myths, or was part of some prehistoric religious ceremony.
Or was it? When he had completed the translation the professor wrote up a paper on his findings and presented it to the university for publication. Their reaction was swift and emphatic: the paper would not be published. The Academy of Prehistory expressly forbade him to publish or even speak of his findings. The world, the academy decided, should not know about the Dropa and their fateful journey to Earth.The Dropa disks tell the story of a space probe from a distant planet that crash-landed in the Baian-Kara-Ula mountains of the Himalayas. The occupants of the spacecraft - the Dropa - found refuge in the caves of the mountains.The stones go on to say how the Dropa were unable to repair their disabled spacecraft and could not return to their home planet, and so were stranded on Earth. If that's true, have their descendents survived? Source:

Ancient sightings:
Speeding disks in ancient timesJanuary 2, 1749
Three globes "like the moon" appeared over Japan. People were so frightened that riots broke out. To try and calm things down, the government ordered anybody rioting "because of the globes" to be executed. Later "three moons" appeared. Days after that, "two suns" appeared. 
Luminous Globe emerges from waterIn another incident that same year, a luminous globe appeared at night and projected beams of light out of it. 21 These seemingly minor incidents are quite remarkable because there was nothing in the skies in 1766 that could project a beam of light, except sunbeams coming through clouds.
There was another picture, but I can't find it. It had a Mongolian or Chinese art style, and it showed large golden skyships with
large propellers coming out of the clouds.
