So there's some strange and very bizarre theories on whether or not  other life forms exist in the galazxy. Here's a few theories on the subject.Geophysical Locations and the effect on Human Consciousness Much research has been done on the effect of certain geophysical locations and their effect on human consciousness, and the reality of a phenomenon called earthlights. The leader in this field of research has been Paul Devereux, who has shown that places along fault lines and plate margins are associated with strange lights that may have a natural origin and may be misidentified as alien craft. He goes further and suggests that abduction experiences may be the result of these lights and places affecting the brain by way of electronic fields. These effects can create dream states within the individual concerned explaining why some accounts seem coloured by personal experience. All this being said there is no doubt that the experiences have life changing qualities, in much the same way as shamanic experience of past cultures. The ability of some people to go into trances in the past was seen as a great benefit to the community. Perhaps a similar state is attained when people experience abductions. This is too small a place to go into this theory in detail but you should check out Paul Devereux's books, Earthlights Phenomena and Power in the Land, as well and his web site:Folklore and Modern Mythology The similarity between descriptions of fairy abductions in common folklore, and alien abduction cases has often been pointed out. The real difference is the appearance of the beings, and description of the place the abductee is held. There are similarities in time differences and slips, strange lights heralding the events, and the changes in witnesses after the experience. The sites of these abductions are also often very close to ancient sites and fault lines. It seems as though the same phenomena is at the root of the events but the belief system of the witnesses has changed, colouring the accounts. There is also the temptation to call the UFO phenomenon modern folklore; strange lights in the past would have been identified with the fairies, whereas now they are often seen as UFO's and whatever the term conjures up to the witness. Hollow Earth TheoryThis theory is one of the most bizarre we will look at in this small selection, it is not as widely discussed as in the early stages of the phenomena, and it is not really one that has ever taken hold in British Ufology. The theory seems to stem from an ancient occult belief that there is a hollow kingdom under the earth inhabited by strange beings. A great deal of old lore suggests hidden tunnels, caverns leading to other worlds etc, although this could prove evidence for other theories such as the belief in other dimensions. The hollow earth is either seen as a base for interplanetary craft, or as a place where strange denizens live, and have always lived, sometimes wandering to the upper regions in much the way as Fungus the Bogeyman does in Raymond Brigg's graphic story. So there are a few theories about UFO's, we will expand this selection in the future and perhaps look at some of the more bizarre ideas that exist.
