Book cover of UFO Sightings: The Evidence

Marvin Harding Author Of UFOs and Aliens, A Glimpse Into The Lives Of Aliens Exploring Our World

From my list on exploring UFOs and alien topics.

Why am I passionate about this?

I am an experiencer who has had a lot of experiences with otherworldly beings for the last several years now, and I am also an inventor in my own right with one patent. I feel I have the ability to pay attention to detail, and I'm very analytical when it comes to making sense of things I can read, see, and hear. In my book, I give detailed explanations of my experiences from my encounters, and I am a very practical person, where I have the tendency to analyze mostly everything I do.

Marvin's book list on exploring UFOs and alien topics

Marvin Harding Why Marvin loves this book

I highly recommend this book because it offers one of the most balanced and skeptical examinations of the UFO phenomenon available.

Unlike many books that lean heavily into sensational claims, Sheaffer applies the scientific method and critical thinking to famous cases, exposing how misidentifications, cultural myths, and selective reporting often fuel the UFO narrative.

His work provides readers with a broad overview of major sightings and trends in ufology, while also highlighting the importance of questioning extraordinary claims and demanding credible evidence.

2 authors picked UFO Sightings as one of their favorite books, and they share why you should read it.

What is this book about?

Engaging and entertaining, UFO Sightings: The Evidence is the most up-to-date overview of the UFO phenomenon, a controversy that gains strength with each new report of strange happenings in the sky. Written from the skeptical perspective, and applying the scientific method to the cases explored, this book differs greatly from the proparanormal tomes widely available today.

"Most broad survey UFO books contain absolutely uncritical presentations of sensational claims," says author Robert Sheaffer. "Typically, pro-UFO books deliberately omit all facts that tend to discredit the cases."

UFO Sightings is unique because it gives the reader a broad overview of the world…

Marvin's book list on exploring UFOs and alien topics

Marvin Harding Why Marvin loves this book

I highly recommend this book because it takes a uniquely scientific yet imaginative approach to the question of extraterrestrial life.

Instead of relying on speculation alone, Pickover blends biology, physics, and astronomy to explore what alien life might realistically look like, how it could evolve, and the environments it might inhabit. He examines possibilities ranging from microbial organisms to advanced civilizations, grounding each scenario in scientific principles while still leaving room for wonder.

This makes the book both intellectually stimulating and accessible, appealing to readers who want more than just UFO anecdotes—they want a thoughtful exploration of life beyond Earth.

If extraterrestrials ever landed on Earth, they would find us extremely strange. Their first intimation of our existence might well be a Super Bowl broadcast or a stray transmission from the Playboy channel. But, of course, they might seem equally strange to us. How strange? Their senses could be entirely different from ours,they might see in the infrared or hear" radio waves.What would aliens look like? An intelligent octopus-like creature is certainly plausible. What about odd numbers of limbs,a three-legged alien with three arms and three eyes? What about an entire planet of immobile, silicon-based trees" that communicate with each…


Book cover of Forbidden Archeology

Ken Goudsward Author Of Fermi's Paradox is Bullshit: The Evidence for Extraterrestrial Life

From my list on rational UFO stories.

Why am I passionate about this?

As a child, I was fascinated with astronomy but discouraged from investigating the UFO phenomenon due to religious reasons. Not until I was in my forties, did I begin to see the strange Biblical hints of what ended up in my writing my book UFOs In The Bible. Along the way, my research led me to diverse related topics including Sumerian mythology and astrobiology which have resulted in a few more books (and more to come). I see logic as a fundamental tool for this line of investigation, and so, I embrace books that engage with the evidence logically. I firmly believe we must all make room for experiencers to tell their stories without recrimination.

This book is not about UFOs. It is not even clear if Cremo believes in UFOs or not. However, one of the tenets of the ancient alien hypothesis is that not only are UFOs a real phenomenon now, they (and we) have been here for thousands upon thousands of years. To this end, it is tangentially interesting to dig into suppressed archaeology and out-of-place artifacts. Forbidden Archaeology is the go-to for those topics, with over 900 pages of painstakingly researched and presented evidence from the geological record that mainstream archaeologists deny, ignore, or rely on handwaving to dismiss. A must-have for any ancient aliens fan.

What is this book about?

Over the centuries, researchers have found bones and artifacts proving that humans like us have existed for millions of years. Mainstream science, however, has suppressed these facts. Prejudices based on current scientific theory act as a 'knowledge filter', giving us a picture of prehistory that is largely incorrect.

Scientific Establishment Found Guilty of Witholding Evidence

The evolutionists’ “knowledge filter” at work over the last 200 years has left us with a radically altered view of our human origins and antiquity. Since 1993, when the controversial book, Forbidden
Archeology, was first published it has shocked the scientific world with its extensive…

Philip Coppens is not afraid to take on even the weirdest of niches within the already weird realm of ufology and paleoarchaeology. He does so with an even keel and an unlimited curiosity. He doesn’t simply parrot what everyone around is saying, but he does examine their claims to see if they hold water. Like in most other aspects of life, there are grains of truth and bald-faced lies. Coppens attempts to separate the wheat from the chaff.

Lieutenant Colonel Philip J. Corso was a decorated military intelligence officer and Chief of the Pentagon's Foreign Technology desk in Army Research and Development. In this role he was tasked with managing numerous artifacts from the Roswell crash, and getting them safely into the hands of hand-selected private R&D firms for analysis, reverse engineering, and technology development. This book details not only his involvement, but the chain of evidence behind these artifacts, as well as technical details on at least a few of the items themselves, and what human technologies were adapted from these alien technologies.

UFOs, Nazis, Roswell, Freemasons, JFK, and the Apollo missions. This book covers a lot of very strange events and theories. Some of these theories you may have heard mention of and they probably sounded completely insane. However, to hear Mike tell it, really makes you wonder if there is some truth there. He unravels a giant rats’ nest of conspiracies in a way that really makes a lot of sense. I’m not saying it’s true necessarily, but Mike presents a lot of evidence that seems feasible. You gotta wonder.

Did ancient “visitors”—of extraterrestrial origin—come to Earth long, long ago and fashion man in their own image? Did they then lift the human race out of the ashes of a great global catastrophe around 10,500 BC? Were the science and secrets that they taught the ancients intended to be a guide for all humanity to the present era? Was this crucial information about our future and our true past hijacked by secretive cabals, some with bad intent and some with altruistic designs, who have held these secrets over the millennia?

This book provides an early history of the modern UFO era by a credible U.S. Military Officer. Read this book or another book you can find by Donald E. Keyhoe.

I recommend Major Donald E. Keyhoe’s book on flying saucers because of the personal passion he has exhibited for the subject, especially for the reality and importance of it. I recall viewing in a video showing how he was on TV telling viewers how important the subject of flying saucers was, while at the same time his TV broadcast was right then and there being censored off the air. Someone like Keyhoe… right in the act of being censored, well, I think, it doesn’t get more emotionally moving than that!

Major Kehoe investigated many of the earliest encounters allegedly between U.S. Air Force pilots and UFOs (so-called “flying saucers”). Keyhoe believed the Air Force was actively investigating these close encounters,…

Dr. J. Allen Hynek was the official astronomy consultant to the U.S. Air Force’s Project Bluebook, ostensibly a project tasked with the legitimate study of and explanation of the early UFO cases in the modern UFO era (the 1940s onward). However, Dr. Hynek, a well-known scientist with a stellar reputation, became disenchanted with the Air Force’s penchant to explain away possibly legitimate UFO cases almost at any cost to the point of being, on some occasions, patently ludicrous. Fittingly, Dr. Hynek went on to become the "Father of Modern-day UFOlogy.”

From being the consummate eminent scientist who espoused the official Air Force line (and lie) that the flying saucers were all bunk to becoming the future “Father" of modern UFOlogy (flying saucers). Well, I think, you seriously need to stop for a moment and ponder the importance of that! My God! There really must be something to this, if this…

From my list on UFOs to read whether you believe or not.

Why am I passionate about this?

I’ve been fascinated by UFOs since I was a kid, but it wasn’t until I met a Martian in 2016 that I started writing about them. To be more specific, I stumbled across a bizarre 1926 article about a man in telepathic communication with a Martian named Oomaruru. I then delved deeper into the beliefs about intelligent Martians at that time. It led to my writing The Big Book of Mars, which touched on the UFO phenomena in the 1940s and ‘50s. But knowing there was so much more to explore, I began writing We Are Not Alone, which is now my 8th book.

A classic study of Budd Hopkin’s thorough investigation using hypnosis as a tool in the study of nearly 2,000 people’s experiences of being subjected to so-called “alien abductions,” allegedly by aliens for hypothetically any of a variety of reasons ranging from medical evaluations of sorts to even possibly harvesting human fetuses! Budd Hopkins has been considered the father of modern alien abduction research. I knew Budd personally and respected him as a smart, thorough, and dedicated researcher.

So, if you believe the Betty and Barney Hill story so that at least their account most likely is true, what then can you conclude if you take the thousands of similar stories of UFO abduction researchers into account—thousands of them! If but one UFO abduction story is true—and there is little escaping the likelihood that Betty and Barney Hill’s story is true— what then must you think of Budd Hopkins’ (and the…

At the time of its writing, Hopkins could not have predicted the impact of "Missing Time," not only within UFOlogy, but in popular culture worldwide. The facts, stories, and theories presented herein laid the foundation for the first…
