The whole argument that Heliocentrists have against the idea that NASA and the elite Scientism cartels, etc..."could never keep a secret this big" (i.e. Enclosed Cosmology), is tantamount to claiming that the NSA, CIA, KGB, MI6, MOSAD, FBI, DEA (Department of Homeland Security), DOJ (Department of Justice), FEMA, ICE (Immigration and Customs Enforcement), and NGA (National Geospatial-Intelligence Agency) could never even exist because these organizations, as a rule, keep just about everything they do a secret. Covert secrecy is the hallmark of The Elite Cartels, and NAZI organization, NASA, the Masonic owned and operated Mainstream Media, and the Masonic educational system, are no exception.
All of the alphabet organizations, including NASA and the military, depend upon the use of lies, deception, propaganda, and subterfuge for their very existence. The fact that people would even ask how a secret as big as the shape of the Earth could be kept a secret demonstrates the depth of mental trauma, mind control, and branwashing that they have incurred at the hands of Masonic treachery and deception.
