The Bible states in 2Ti 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
2 Tim 3:16 All Scripture is God breathed.... blah blah.
The Chronicles of Narnia is inspired by God. The Bible is the very word of God, according to it. There is a difference between "inspired" and "God breathed." Unless, of course, you also believe in Aslan.
Reproof & Correction, for instruction in righteousness: Earth is Flat, Menstration and giving birth are sins, Rape is a crime of theft against the father, Houses get plagues, Pi = 3, Pigeon
blood cures Leprosy, Store houses for Rain and Snow. A place the Lightning dwells. Above the sun and moon, above the solid canvas that is the sky, a dome
with windows that allow the 'waters above' to pass thru and become rain. Magical Potion that reveals whether wife is sleeping around (Num 5).
The Ark has only be built at 1/2 scale, and even then requires Steel Bracing.
Edit: the Earth is close to a Sphere, ie. a Ball. The Earth is not a Circle, ie. A plate. Climb a high mountain or go to the top of a tall building. Turn 360 degrees. What shape is the Horizon in? A Circle. Clearly something only an "All-Knowing" God would know, eh? They also thought, if you went high enough you would see the Whole world. Again, Flat.
