I find the discussion intriguing.
My position at the moment is that there may well be something odd about what we (are made to) believe.
But i don't believe the earth is flat.
I think a flat earth is impossible.
it may well be a 'psyop' of some sorts, to make Bible believing Christians look stupid.
Just like false flag terrorism is not condemned by Muslims sometimes, a group of Christians choose to stick with the flat earth model (which is from God's viewpoint) as described in Scripture.
What feeds the dismissal of the round earth is the credibility deficit of NASA.
I mean like, how convenient the van Allen radiation belt was not yet discovered when they went to the moon.
Otherwise they wouldn't have survived it...
And there are many more examples of (possible) NASA deception.
And there are many more things the world teaches us that oppose God or truth in general.
So, the mistrust is justified, but that doesn't make the earth a flat plane.
