    1. One of the most poorly organized and repetitive books I've read. Instead of a so-called scientific viewpoint, Ashpole gives us a neverending mobius strip of reasoning for and against the existence of alien life in the universe. It could have been summed up in a chapter, but this author leads us up and down the same ladder over and over again. What's most distressing is that he earnestly considers that someone, somewhere will pursue alleged evidence of aliens in our backyard with scientific tools [...]

    2. The main topics were interesting, but there was insufficient material to fill an entire book, resulting in a highly repetitive argument using the same supports basically to say that SETI is too narrowly focused on their communication efforts (definite anti-SETI vibe going) and that no one is doing true scientific method on UFO data/sightings. The few specific examples of UFO science/data that both exists & was presented is fascinating. I am sure that the lack of research, data, fact, etc did [...]

    3. The never ending searchThis book goes into detail about the possibilities of alien life. Using a lot of scientific disciplines of how other life forms could originate from other planets. The book covers a lot of ufology.
