@sourdough more like Christians trying to convince people that the world is flat and that the entire universe orbits around us. Yes NASA has lied in the past but some Christians take these lies and exaggerate them to stretch the flat earth theory because it makes them feel good.
Best of luck trying to find ONE flat earth theorist that isn't Christian. I have tried many times and could not find one except for those who don't associate with organized religion but still believe in Christ
