Dutchman Stefan Denaerde talks about his alien encounter after his boat hit a USO/UFO
In 1969, Stefan Denaerde came across an encounter with eight extraterrestrials after accidentally stumbling across a UFO. His book about this incident became an instant bestseller (Amazon link).
Based on the author’s encounter with the aliens, Alien Civilization was released in 1969. Through his encounter with the aliens, the author was able to see their environment through their computers and film images. According to Denaerde, he was surprised by how advanced and high-level technical knowledge is used to determine life on a planet that has a population of 5000 people per square kilometer.
