That's prudent.
I know numerous conservative christians and muslims. Until about a month ago, I had never met anyone (or realized I had met anyone) who believed the world was flat. I daresay the vast majority of christians, jews, and muslims during the past 2000 years – those with some education, no matter how conservative – believed the world was a sphere and saw no conflict between the shape of the planet and their religion.
It's not my wish to debate whether or not the Bible implies a flat earth. I'm simply curious about the flat-earth model, which (as far as I can see) is incoherent. Can anybody explain to me how Night and Day can happen simultaneously in a flat-earth world? It seems that's absolutely impossible.
This is different from disputing Evolution – in the sense that Creationists DO have a coherent alternative explanation. Even though I consider that explanation incorrect, I would regard it as coherent. I can restate Creationism as a plausible theory, which (theoretically) the facts may or may not confirm.
For instance: Humans were always humans, and they had a first ancestor who was invented from scratch and who did not descend from anybody. Humans and apes are not distant cousins. Ostriches and hummingbirds did both not descend from some other bird-like creature. Tigers and elephants did not both descend from some other hairy creature. Whales are not descended from land mammals. Land mammals are not descended from sea creatures. Life itself was invented and placed on earth and did not arise spontaneously. Each species has always been as it is now. Some have gone extinct. Others might have been invented later and placed on earth. Complex organs like the eye were designed and did not arise spontaneously.
I don't regard the foregoing paragraph as true. But it is coherent. I can understand it. It's internally consistent. The inventor of species could (theoretically) be God or aliens or robots or (maybe some day) even humans. That might be wrong as a matter of history, but it's not crazy at all. Superficially it's actually quite implausible and counterintuitive to believe that complex organs can be invented on their own or that whales and mice and humans and giraffes are all cousins with the same Grandpa. I believe the facts show Evolution to be true. But it is a surprising kind of truth, if true.
That's what I mean when I say Creationism – true or false – is coherent. But this flat-earth world? Try as I might, I cannot restate or explain that hypothesis at all. It crumbles to bits in in my hands. The most familiar observations – sunsets and sunrises, daytime in the USA and nighttime in Europe, summer and winter – have to be ignored, apparently, in order to believe in a flat earth.
