What type of Extraterrestrial beings allegedly crashed at Roswell New Mexico they said be from Zeta Reticuli?

Grey aliens or the Zeta Reticulians. Zeta Reticuli is a double star system, where one of the stars has bursts of UV radiation.

Double star systems have a habit of not keeping planets in stable orbits (there are exceptions, but they are extremely rare).

UV bursts have a tendency to sterilize the planets they hit.

it was Zoidberg

They are called the grey aliens. They supposedly are the most common visited ETs that comes to our planet and is popular in media. Zeta reticuli star system is where they come from. However there are many types of grey aliens, these were just one of them.

Some came here from a planet called serpo. These grey aliens are the only ones to have human like eyes with pupils amongst the bunch.

The shorter Greys from Zeta Reticuli.

The short Greys control the Reptoid Aliens who in turn control the Illuminati and the New World Order.

The short Greys are controlled by the tall Greys.

The tall Greys are controlled by the Beings of Pure Energy from Another Dimension.

The Beings of Pure Energy from Another Dimension are controlled by my cat, Snookums.

That was no UFO, it was an experimental "Crew escape module" proposed for one of the new jet bombers being developed back then. The air base near by was devoted to developing such things like ejection seats, etc.---- The "Aliens" were actually Institutionalized humans suffering from "severe retardation" --a Congenital condition known as "Cretenisim" which results in short stature, big heads and polydactylisim (extra fingers and toes)-----who had no families, being used as "Human crash test dummies"------The real source of the "Problem" the use of helpless humans as test subjects would have been a BIG Scandal at the time should word have gotten out.---The Government responsible for the "Tuskegee Experiment" was not beyond this sort of chicanery.---It was also TOP SECRET defense related matter too-----This explains the over-reaction of the troops in silencing the witnesses, and to let it continue to go on as a "UFO incident" to hide what was really going on.

It was thought to be the Greys.
