I found Mr. Bate's book, ALIEN INTRUSION to be very well written, and engaging; his information is carefully researched and I believe he gives a very responsible perspective on a subject that is highly conjectural and given to speculation, yet passionately believed by countless numbers the world over.
Mr. Bates not only gives a reasonable response to so-called 'alien visitors from another planet' he also confronts the theory of evolution. If aliens who are several thousand or perhaps hundreds of thousands of years more advanced than us, then evolution must be factual in order to establish credibility to this other-worldly phenomena.
As has been verified in other works and research, Mr. Bates says that 2 to 5 percent of all sightings have no reasonable explanation (regardless of whether or not they are 'aliens') and that up to about 20 million Americans have claimed to have seen a UFO and even 4 million claim an abduction experience.
In 1947 a Gallup poll it was revealed that the majority of Americans didn't believe UFO's were alien space craft, but rather "illusions, hoaxes, secret weapons or explainable phenomenon".
