Any given person has a set of assumptions, a set of knowns, a set of known unknowns(questions), and a set of unknown unknowns.
If someone, Alice, shares her perspective with you, and Alice’s perspective, in comparison to your perspective, reduces your number of assumptions, converts some of your known unknowns (questions) to knowns(answers), and converts some of your unknown unknowns into known unknowns (questions), Occam’s razor suggests that Alice’s perspective is, at the very least, less distorted than your legacy perspective and is therefore a worthy candidate perspective for you to consider for adoption.
If someone offered a perspective that reduced your number of assumptions, converted some of your known unknowns into knowns, and converted some of your unknown unknowns into known unknowns, and part of that other perspective included a spheroidal earth, what would you do?
To help imagine what this perspective would look like, it would essentially be able to explain YOLO vs reincarnation, global flood myths, ancient lost civilizations, and it would be able to decode religions and bridge the core that unites them all with science. If a perspective like that was presented to you and, as a necessary component of that perspective, the earth was a spheroid, but basically every other major question you could possibly imagine is satisfactorily answered by this perspective, would you abandon the flat earth theory and adopt that other perspective?
