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
[1] 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

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.
