Many spoke of the earth being flat , or supportedby Elephants , but in the scriptures we find what science also revealed years later , now of course a wise man could reason that the earth was round , but to say that it hung upon nothing , where else does one find such wisdom , God revealed it to certain ones to have such understanding . Many other wise men had no grasp of such knowledge .
I will just comment on this single example of re-inventing what the Bible says to sound more palatable to modern man who has a better understanding. The roundness of the earth described in the Bible was more in line with a flat coin with round edges. If God wanted to avoid so much trouble in the dark ages and wanted to help Man understand the universe, He could have seen to it that the Bible described the earth as a ball that goes around the sun (not the center of the universe) and that stars are not little tiny lights that orbit the earth but are other "suns" bigger than the earth, just far away.
You seem to do this with other points, just as the JW's do- try to say what the Bible doesn't say and re-invent what it meant to indicate that it was different from current beliefs. It was not radically different and left out so much.
