Thanks Lex. You and Lee need to read more and talk less. Other civilizations have been documented in the book HUMANS ARE NOT FROM EARTH. The author was in the USAF for 35 years. They have proven over 60 species are not in Space they are here on Earth and the run the world. Just look at the EARTH. It is mostly Evil. We are a Prison planet . Over 100 million humans were murdered in the 1900's alone in the wars orchestrated by Earth Aliens. Thanks
