Unfortunately and sadly, even if this time of his life was known, it would not lead to anymore individudals living their daily lives according the principles that are known.
If the God of the Bible thought it would change even a little bit of what he sees as he observes the actions and lives of the inhabitants of the earth, he would have included those years.
For the record II Peter 2 1:3 states God, “hath given unto us all things that pertain unto life and godliness.”

I don’t think it’s wrong to imagine what this might have looked like, with the humility that we don’t really know the details. But all would have been in character of God. I think my characterization of a boy who was exceedingly helpful would not have been off the mark. But if people knew the details, then we would have silly things like Knights of the Picked Up Books and such. A sparing treatment of historical details minimized this risk.
