Why is the term "Zeta Reticuli" so widely accepted?

Home system
Zeta Reticuli Greys come from Zeta Reticulan, the 4th planet out from Zeta2 Reticulum, near Barnard's Star, which is a neighboring star system to Orion. The constellation Reticulum is a fairly small collection of faint stars, of which zeta is barely visible to the naked eye even though it is relatively close to us at approximately 40 light years. The dim point of light known to us as Zeta Reticuli is actually a binary star system, and its two stars, Zeta Reticulum and Zeta2 Reticulum, are each very much like our own yellow sun. It is not visible in the northern hemisphere.
Their day is 90 hours long and the year is a little over 432 of our days long. Travel time to that location is about 91 days by Reticulan jumpcraft. are both stars in the Constellation Reticulum in the Southern Celestial Hemisphere.
These greys have their best-known bases in New Mexico and Nevada but are also known to have bases in many countries of the world.


Description
The most commonly seen grey is around two to four feet tall, very slender and delicate looking, small beings and light weight, extremely penetrating black slanted eyes with no pupils, almost vestigial mouth and nose, a very large head with a pointed chin. The skin color varies from dark grey to light grey, tan to tanish grey, white to pale white. They have no hair on their bodies. They have evolved beyond the need for reproductive systems or digestive systems and reproduce by cloning. Their genetics are partly based on insectoidal genetics.

Activity
Their science deals largely with the study of other life forms and genetic engineering. They have supposedly had a part to play in the alteration of human genetics over thousands of years. It seems that they may be trying to cross breed with humans in order to create a "mixture race" that would be better than either.

Organization
There social organization is similar to ants with a very rigidly defined social structure but they are technologically advanced and seem to be in a conquest mode. There seem to be two main social classes. One is the more hawkish and is more abrupt, crude and blunt. The more dove-like ones are more refined and capable of a more business-like behavior towards humans, and prefer to use more "diplomatic" behavior to gain control over humans. This type of Grey is what I believe is being referred to as the "Orange" class of Greys. These greys are servants to a master race of reptilian-type aliens and are trying to prepare the earth for their arrival by gaining control over the earth through many means. They tend to enjoy the feeling of freedom they have on earth, away from their masters and would desire the help of humans in confrontations with the reptilians.

Friend/Foe
They seem to be emotionless (by human standards) and therefore are seen as cruel in their treatment of human beings. They are able to take human lives without any regard for that individual. They apparently can use certain substances of the human body for their sustenance and therefore appear to be carnivorous in regards to humans. This could apply to physical or mental fluids, an experience reported by many abductees that felt like being “vampirized” as aliens would use their fear as a recreational drug.

In 1968, Marjorie Fish of Oak Harbor, Ohio read Fuller's Interrupted Journey. She was an elementary school teacher and amateur astronomer. Intrigued by the "star map", Fish wondered if it might be "deciphered" to determine which star system the UFO came from.
Assuming that one of the fifteen stars on the map must represent the Earth's sun, Fish constructed a 3-dimensional model of nearby sun-like stars using thread and beads, basing stellar distances on those published in the 1969 Gliese Star Catalog. Studying thousands of vantage points over several years, the only one that seemed to match the Hill map was from the viewpoint of the double star system of Zeta Reticuli. Therefore she concluded that the UFO might have come from a planet orbiting Zeta Reticuli.
