My book is informative and a collection of question asked by more and more people Concerning Aliens and Extraterrestrials. In my book I discuss and explain why there are two separate Entities - Aliens and Extraterrestrials. I also explain where Aliens come from and why ExtraterrestrialsAre on earth.
