I’m surprised that many claim to know everything about aliens and UFOs but have never heard of the Blue Planet Project document!
It is one of the most influential documents about alien biological entities and space technology in our history.
Many of your favorite authors have used these documents to build their theories, and you would be surprised by how many of them are debunked or reinforced by the information in the Blue Planet Project Book. http://www.blue-planet-project.com/
