My nuanced take is this: Earth ain't flat because of seasons, scalable micro/macro patterns and general roundness of floating bodies, but the offical measurements of the horizon line is messed up and NASA lies in so much, including its depictions of earth on pictures, the use of fish lenses, studio tricks, Devon Island (for Mars)... There has to be explanation for their misconduct, like (rabbit hole, here, I know!), Van Allen's belt, dark project money for already existing off planet projets using retro-engineered alien tech ("exotic" energy and weapons from nazi research), probably intergalactic treaties where the moon is used as a control grid/watch tower.... Anyway.... !
