Reviewed by Leonard Smuts for Readers' Favorite

The question of extraterrestrial visitation has been the source of intrigue for generations, and conflicting theories abound. Newly declassified documents have fueled the debate. Robert Allan brings readers up to date with The Phenomenon. This book adds research from ancient texts that go back 4,000 years, providing a broader historical context and an extended timeline. The change in terminology is interesting. Vehicles formerly called Unidentified Flying Objects (UFOs) are now referred to as Unidentified Anomalous Phenomena (UAPs). Substantial evidence is presented from reliable sources, including radar tracking and accounts by professional aviators. Many witnesses, including Air Force officials, have chosen to remain silent. The UAP situation has been distorted by populist literature, mistaken sightings, cranks, and faked photographs. Not all contacts are benign, and there have been instances of alien abduction and paranormal activity. There are also reports of UAP wreckage analysis and reverse engineering. There is also an interesting link between UAP activity and nuclear weapon facilities. This book is unique in reviewing sightings that were reported hundreds of years ago, backed by revelations from ancient scripts, and the discovery of advanced cities and civilizations. Some startling possibilities are explored, such as whether we are a zoo to be studied by alien races, and to what extent they manage our activities and assist our development.

Robert Allan has weighed the growing body of evidence to present a balanced view and plausible explanations, noting that there is still resistance from both the public and officialdom to accepting that beings from other worlds have regularly visited Earth. The ancient Sumerian texts are seen as an actual account of events, rather than mythology, and should not be discounted. They paint a stark picture of colonization by the gods dating back thousands of years, and a genetically engineered race that followed. Input from shamans and psychics who interact with other worlds is also featured. From descriptions of UAPs to eyewitness accounts of events, The Phenomenon presents a series of hypotheses concerning the UAP phenomenon. The book steers clear of conspiracy theories and relies on the evidence to speak for itself. The book is the first in a series and is the product of rigorous research. Sources of information are quoted in detail. Although it intentionally presents no definitive answers, it brings a wealth of information to the reader with unusual clarity and depth. He encourages readers to maintain an open mind. It will be of great interest to a wide audience and is highly recommended.
