The Zeta groups are Negative Aliens, from the Reptile Insectoid Collectives that formed alliances with the Drakonians to take control over the earth, and to which are also referred to as the NAA. These groups used technology to open Wormholes that were blended together to create the power required to attempt to pull the earth body into the Black Hole System leading into the phantom matrix where they exist, and then could gain total control over the planet and humanity. The Zeta contacted the earth world governments during the first World War to make agreements for the barter of earth resources and human genetics in exchange for Grey Alien advanced technologies and assorted militarized weaponry. The Zeta were involved in colonizing Mars and were active during the Atlantian culture that eventually led to the fall.
The Zetas are interested in Breeding Programs to create Zeta human hybrids in order to maintain control over the earth in the future timelines. Thus, they formed covert agreements with the world governments and allied forces during World War II in order to reproduce their own race, and through which they could use the Zeta Hive Mind to more effectively mind control the population of the earth. During World War II treaties were made with the allied government, and as a result, several organizations, black operations and covert groups such as Majestic 12 were set up to further administer to these treaties, while secretly testing out assorted alien technologies, weaponry while reverse engineering space craft, and these activities are what began the factions created for the Secret Space Programs and high level testing of these technologies in the Military Industrial Complex.
