Ancient Astronauts

Since the galaxy is billions of years old, Life may be just starting to evolve on some planets, There may be worlds at the state like our cave man days and some like our stone age days. There might be worlds which are just starting to explore science. Some are at the stage as we are now, where beings are developing technology quickly, starting to understand the planets, stars and basic physics. They might be using fossil fuels and radio waves and starting to play with dangerous technologies. These civilizations will look out into the cosmos and wonder if other life exists like we do. They might just started exploring their nearby planetary bodies like we do. This is a very crucial stage where a civilization is capable of destroying itself and its world. Beyond these, there are civilizations who are more advanced than us, some are million and even some are billions of years beyond us. They could have found a better way to cross this enamorous void and climbed every the star system in sight and should have visited earth long ago. If they might have reached earth in our primitive days then our ancestors might have mistaken their technologies as divine entities and called them as Gods from outer space.

The Ancient Astronaut theories or Paleocontact are various proposals that intelligent extraterrestrial beings (called Ancient Astronauts or Ancient Aliens) have visited Earth and that this contact is linked to the origins or development of human cultures, religions and technologies across the world. These theories have been popularized, particularly in the latter half of the 20th century, by writers like Erich von Däniken and Zecharia Sitchin. This theory have not received support within the scientific community. But ancient astronaut theories have been widely used in science fictions.

This theory suggests that, the ancient aliens visited earth long back and they created modern mankind by improving the genetics of the sub-humans. The purpose of mankind was to serve the Ancient Astronauts, principally by providing food and mining and construction labor. The Ancient Astronauts did not allow humans to view them or go near them. Except priests who had cleansed and covered themselves and spread a germicide, suggesting their susceptibility to earthly diseases. They apparently moved above the Earth in spacecraft using chemical fuel, and only landed on mountaintops or other rocky outcroppings; this reduced the dust and provided physical protection from humans, and disease control. They taught humans agriculture, astronomy, engineering, and provided the first laws. They then departed from the face of Mankind.
