Ultra top secret technologies, in development and function, often referred to as Black Ops has known to occur at the infamous Groom Lake (“Area 51”) and elsewhere also, can explain much of this phenomenon. Orbital devices, such as satelites contributes to sightings as well. Naturally occuring meteorological and sub-orbital events can explain much of this.
Hoaxes are a part of all this of course. When one whittles all of this down, there is a small percentage of sightings that are unexplained, and seemingly beyond any terrestrial explanation.
Dr Jacque Valle and Dr. John Mack were two investigators into the UFO phenomenon, and both doctors concluded that these sightings, vessels, travelers are not what they appear to be. Dr. Valle went on record as saying, that these things are less physical objects, and more like windows into a hyper-dimensional reality.
Dr. Mack conducted hundreds of interviews with witnesses and found consistencies that corroborated the stories of other witnesses, yet with enough variation to exemplify credibility.
I recently re-read a book I have by Drs. Chuck Missler and Mark Eastman, called ALIEN ENCOUNTERS which you can find in your local bookstore.
I would highly recommend it as it has sources and bibliography thats quite useful to any one who wants to know more about this subject.
What intrigues me is that those who are supposedly psychically linked to what they actually refer to as our ‘Space Brothers’ (!!!) have proclaimed that the human race is about to experience a paradigm shift in their evolutionary process, whereby they will cease to be homo sapien, and become homo noeticus, a far more powerfully spiritual species, almost god-like in their development. Yet collectively, we are being held back by those who adhere to outmoded, archaic belief systems that are no longer valid in this coming Order. These humans will have to be excised from the global community and consciousness so that those remaining can enter into this New World Order and acheive godhood (I’m not kidding, they have said this). So these Space Brothers will evacuate these humans, these impediments off world for the good of the planet. I wouldn’t give such things any credence if not for one thing: the Bible itself speaks of those belonging to the body of Christ will one day be removed off world, and enter heaven (1 Thessalonians 4:16–18; 1 Corinthians 15:51–54) while the rest of the world enters a time of incredible deception and tribulation, as made popularly known via the ‘LEFT BEHIND’ series by Tim LaHaye.
So what are these things really? I believe they are non-corporeal, highly super-intelligent beings who are inimical to the (spiritual) well being of the human race.
