Flat Earthers hold their belief because they know something's off about the official narrative and it's the closest they've gotten to the truth. It's the most stigmatized and ridiculed theory, not because they believe in a flat earth, but rather the other truths many have uncovered along the way.

Speculation
Yes, it makes sense to me. But, again I don't consider myself a Flat Earther, nor do I pretend to know what shape Earth has. But, it's definitely not a spinning ball and we're not rotating around the Sun at 66,600 miles/hour.
From my research looks like heliocentrism was invented and calculated on by Jesuit priests of the Catholic Church. The theories from their front man Nicolaus Copernicus of the Third Order of St. Dominic were supported by Jesuit astronomer Giovanni Battista Riccioli. The other thing I find odd Nicolaus Copernicus, Sir Isaac Newton and Albert Einstein were all high rank Freemasons and all occultists.
