They will distort the truth in any way they can. After the globe came evolution, meteorites, planetary impacts, aliens, and global warming. It presents a world where God isn't above us, at least not directly, hell isn't below us, and the universe is physical, random, dark, and cold. The earth isn't the center of creation, and the sun worshipers get to deceive us into believing we revolve the sun, and it dwarfs us in size.
It's generally disorienting and enables more deception plans and lies to exist. It's impossible not to be a creationist on the flat earth.
