Lazar additionally claimed that during his joining the program, he read briefing documents describing the historical involvement of Earth for the past 10,000 years with extraterrestrial beings described as grey aliens from a planet orbiting the twin binary star system Zeta Reticuli. As of September 2019, no extrasolar planets have been found in the Zeta Reticuli system. In 1989, Lazar said the seats of the saucer he saw were approximately child-sized and that he had seen alien cadavers of a corresponding size. He also said that while walking down a hallway at S-4, he briefly glanced through a door window and saw what he interpreted as two men in lab coats facing down and talking to "something small with long arms". Three decades later, he said he did not think he saw an alien, but speculated that he saw a doll used as reference for the size of the alleged aliens, and that a nickname used for them was "the kids".
