I watched a video on TFE where there was a minister guy saying the Earth is flat because the bible says so and that any evidence to the contrary is manufactured by (literally) Satan and the US government and that they may not be able to prove it one way or the other, but they have to have faith in the word of God.

There's literally nothing you can say to that.
