In the 1980s I was a regular contributor to the esoteric magazinePlanet, by publisher Três. They published entire issues with a single theme. I volunteered to write about events in the past that could indicate the presence of aliens in the formation of human civilization. I have always believed in this possibility, influenced by the Swiss writer Erich Von Daniken, the author of the best sellerThey were the Astronaut Gods?. I also studied with São Paulo professor Rollim de Moura, one of the greatest Brazilian experts in this field. To write the editPlanet, I delved into dozens of books, including theOld Testament, aEpic of Gilgameshit's theTibetan Book of the Dead. In 2019 I revised the text, added new information and illustrations and created the Kindle Amazon digital version.
