I would say that for us, this sounds reasonable, but we're talking about the Apostles and other authors of the Bible. Do you mean that they were no more advanced than us such that they could express the truth perfectly? I would disagree with that since it would obviously diminish the power of God's word.
FK: "God would build in error, just to let men be glorified by correcting it"
But you already believe that God created Adam to fail!
No, I've said several times that it was not the purpose for creating him, although it was a part of God's plan. No error involved. Human history has evolved just as God wanted it to.
Well, God created Adam either to fail or to succeed. Given that he failed I suppose God didn't want him to succeed. If everything is according to God's plan, then He created humanity so that it may fall in order that He can rescue some!
