Then how can you claim flat earth is the truth? How do you know you're not just completely falling under the government's plan to believe in a flat earth?
See, the earth is really a figure 8. They perpetuate the round earth so noone will know the true form. And to further keep people from discovering the truth, they purposely leak out details of the earth being flat and details of a huge global conspiracy. So now, instead of thinking "hey, earth is round", you think "but it is really flat!", when in fact, it is a figure 8.
Your belief in the flat earth is exactly what the giant global conspiracy wants you to believe, and you're just another tool in the giant "figure-8" cover-up.
