To imply that the Earth is flat you aren’t just saying that NASA is lying. You aren’t just saying that there is a conspiracy within one company, you are implying that there is a conspiracy between the worlds 71 space agencies 13 of which have launching capabilities. Not only are you saying all 71 space agencies are lying about the shape of the Earth, but you are saying that everybody within those agencies are lying or being fooled by the respective companies. Furthermore every astrophysicist in the world in your implications a “Scam Artist” getting paid to do research through telescopes and instruments that would be useless if the world were flat. So roughly 75,000 people are lying about what they do for a living. Not only is it absurd to imply that the NASA program under the United States government could pull off such a conspiracy, but the fact that all the 71 space agencies in the world are taking part in some conspiracy and every astronomer , astrophysicist, and astronaut are involved. It’s just absurd to think that so many people are involved in this major conspiracy.
