Alien Ancestors: The Gods Of Man

Are aliens from our past returning? 

Aliens in our ancient past are practically common knowledge. They came millennia ago, fought a great war between themselves and left behind a history of their occupation, vestiges of a long lost culture from another planet and a sudden departure – but why?

After eons, these beings have now returned and are engaged in a battle with humanity itself and some researchers believe they have returned to manipulate and use mankind to a sinister end.
