Here I have documented some books for your interest and further reading into Reptilians.
Carl Sagan
The great cosmologist Carl who developed the legendary Cosmos book and TV series had written the following book about the evolutionary development of man, along with mammalian and reptilian brain connection and its overlays.
We have both reptilian and mammalian brains. The latter overlays the reptilian brain which is known as the R-complex.
This reptilian brain is where we get the flight or fight response, survivalist instinct, and strong uncontrollable emotions. It does not reason or try to work things out it just reacts to situations and events. The mammalian brain overlaying this R-complex tries to control these emotions with logic and reason, along with imagination and creativity to solve problems.
The Dragons of Eden shows how the human brain works and why it has evolved to operate the way it does today. It helps us understand the emotional problems in our lives and how we interact with people and the outside world.
R. A. Boulay
A researcher who wrote the following book that will make you question your current views of humanity’s past.
Flying Serpents and Dragons are about Mankind’s Reptilian Past, written by someone who used to work in the NSA as a cryptographer. Was Adam and Eve human? Who actually created them and for what purpose? An interesting book going into ancient history.
Betsey Lewis
Betsey is a researcher and psychic and has written many books.
Ancient Serpent Gods reach further than other material about our ancient reptilian past. It provides information and insights that dinosaurs survived the extinction. It put forward the argument that the dinosaurs evolved into reptilian races and went underground into the Earth.
I think this was concluded by scientists even back in the 1990s that if the dinosaurs had survived the mass extinction then an intelligent humanoid reptilian form would have evolved out of the dinosaurs.
However, did all the dinosaurs go extinct? Birds it seems are direct descendants of dinosaurs. There are many people who have witnessed flying pterodactyls all over the world.
