Which model does not match?

  Isaiah   40:21 - 22   KJB
[21] Have ye not known? have ye not heard? hath it not been told you from the beginning? have ye not understood from the foundations of the earth? [22] It is he that sitteth upon the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:

500 + years ago, everyone, the writers of the Bible inspired and preserved by God, and every single cizilization knew that the earth is flat.

And God Himself always knew that the earth is flat and has a firmament (Genesis 1:14-18 and 28)
