A good starting point for people getting into the UFO phenomenon. Jim Marrs offers an almost encyclopediac look at UFOs through the ages, from ancient texts like the Bible all the way up to Roswell and Cydonia. He also gives us a peek into how the US military has dealt with UFOs since the 1940s. This is no sensational book full of crazy stories but a book full of well written research. Jim Marrs leaves it up to the reader whether to believe any of this or not. Read this and Whitley Streiber's Communion and see if you'll still be able to sleep at night.

This book is great for those who might even just be a little interested in UFO's/government cover-ups. I'm really into this stuff and have read and watched just about everything and anything on this subject, and this book still had more to offer. And i'll admit, that sometimes it's hard to keep my attention. But this book does the job well. You'll find yourself waiting to read the next chapter just to build the suspense. Topics include: UFO/NASA conspiracies, Biblical/UFO events and history, crop circles, Marsian Conspiracies, and even a look at Remote Viewing and a few other Mind-Based sciences. This book has everything in its almost 600 pages. Definitely worth buying.

If you're new to the whole UFO topic, this is a hard-hitting, but sometimes slow-reading introduction. If you've already read everything written, it's a concise review. Marrs doesn't use the most exciting or creative writing style in the world of books. But the information is as objective as you'll find. If you really think we're the only life in the cosmos, don't bother. But if you find the possibility of life 'out there' intriguing you'll appreciate this book.

This book explores all the dimensions of UFOs from the dawn of their existence to the present. No stone left unturned. All the scenarios, the meaningful sightings and pertinent analyses. A magnificent book par excellence!

Reads well, better than most UFO books . Just a well done overveiw of everything UFO and Alien without being dry or mixing in too much opinion or religion. If you just want one UFO book this is it

This is an interesting book Jim Marrs has written, which comprehensively chronicles the UFO issue from biblical time to the present without a lot of the typical tedious sighting reports. On this basis alone it is a very good book for anyone interested in the subject, but how hasn't done a lot of reading on it yet.

Mr. Marrs looks at all aspects of the UFO and related issues, like the evidence for the artificiality of our own moon, evidence of ancient astronauts in artifacts found on earth, Mars and the moon, missing time and abductions, remote viewing, cattle mutilations, Chupacabra, and crop circles, all of which flows very nicely until the reader gets to chapter 12, "A Metaphysical Exam," where he quite frankly lost me. Here I was looking for the "Alien Agenda" which might have been finely cloaked in the chapter, but if it was it escaped me. I guess I was looking for the secret, but what I got was a bunch of multidimensional multi-spiritual speculation.

Mr. Marrs did relate some very profound statements, one of which from Linda Moulton Howe regarding an incident which occurred to her at Kirkland Air Force Base in Albuquerque, NM on April 9, 1983, which seems to imply that a possible reason for all of the UFO secrecy might be that the human species itself is the product of alien technology, putting the veracity of all of the worlds religions in question.

Marrs also relates a troubling story about the detection of two giant satellites which were orbiting the earth in 1953, two years prior to Sputnik. Army Ordnance officials at White Sands, admitting they were there, said that they were tiny moonlets similar to asteroids that had come from space and entered orbit around the earth. In October 1954 NASA reported that they were receiving strange signals from an unknown orbiting earth, and then prior to 1955 the objects disappeared as did the story and public interest. I bet you never heard anything about that before.

There's lots of similar good stuff in the book, and while it's been more than ten years since the book was originally published, it is still certainly worth the read, even if the alien agenda is still not clear.

Jim Marrs has written a compelling account of aliens among us. To those few unenlightened sceptics who remain unconvinced of extraterrestrial presence, I suggest they study the audience of any Jerry Springer show. In a nanosecond of cosmic clarity, their doubts will fly away on the Mother Ship of Blazing Belief.

This is a must-read. It's a full-on, historical reference for practically everything UFO-related. Fun and interesting... get it!

Alien Agenda and it's importance to the world of UFO's begins immediately with the first chapter. I am not going to tell you about the MOON, but you will find that with the reading, the first chapter is as important as the whole book with extraordinary and almost unbelievable facts to support the revelations Jim presents. As usual in all of Jim Marrs books, his research is mind-boggling with information from many sources, FOIA data, books, other UFO Researchers, and INSIDE sources; but with Alien Agenda, he out-does himself. If you buy this book for just the first chapter, your money will be well spent and you will have a book of historic significance to keep in your library for your children and grandchildren to read many years from now.

Just because I have centered on the first chapter only goes to show the reader what to expect from the entire book. After Alien Agenda, I will continue to purchase Jim's books as soon as they hit the bookstores.

This is one of the most interesting books i have ever read. this book is long, about 600 pages, but Jim Marrs does a wonderful job of researching the topic of ET and UFO visitation to this planet. The writing is quite easy to read and it is a hard book to put down. Of all the books on the topic of ET and UFO, I believe this book is the best. I would definitely recommend this book to anybody and for any age group. I look forward to reading more of Mr Marrs' works.
