There are a lot of conspiracy theories about the government floating around, usually along the lines of "the government is doing something unsavory to get what it wants."
For example, some people believe that the shooting at Sandy Hook was fake. The claim is that the government staged a fake shooting to use as evidence that America needs more gun control, so they could take everyone's guns away.
There's also some who believe that the government was responsible for 9/11 because they wanted an excuse to invade the middle east.
I don't believe either of those ideas, but I at least understand them. Government wants to take guns away, so it stages a shooting. Government wants to invade Iraq, so it fakes an attack to get people riled up. Whether it's true or not, it makes sense.
The Round Earth Conspiracy is a bit more confusing. In order to keep up the ruse, every government on Earth has to be involved in falsifying maps, movies, flight plans, star charts, ect. It's not just the shape of the Earth that's in question either. Practically every field of science must be altered to make the conspiracy seem true, physics, cosmology, and geology to name a few. Entire companies must be created to design spacecraft and other technology that is impossible to create. Magazines, textbooks, entire universities, public transportation, and global trade must be censored. Weather reports based on a round Earth must be created. History would probably need to be censored to some degree as well.
This culminates to a cooperative effort by every government across the world that costs countless billions of dollars and hours of manpower.
And they're doing all this for... What exactly? For evil? Are we all just being trolled? What could they possibly gain from doing all of this? The FAQ says that it was to pretend that America had space-weapons, and that the people orchestrating the conspiracy somehow don't know that they're wrong. They just couldn't figure out why their rockets wouldn't work, so they decided to just start a conspiracy. So does that mean that the government created the Round Earth Conspiracy, and then NASA tried to design rockets to go into space using the Round Earth Model, but they didn't work, so they just created their own Space Travel Conspiracy to pretend their rockets worked, not realizing that they were victims of an even greater conspiracy? And if everyone in power has to be involved in the Round Earth Conspiracy in order to make it work, then who's going to be fooled by the Space Travel Conspiracy? There isn't a whole lot of information on the conspiracy in the FAQ.
It seems like a big convoluted mess that doesn't benefit anyone.
