And you prove the Truth of Scripture by not being able to comprehend the metaphors that are obviously being used (regarding the circle and the clay). To read into the Matthew 4 passage an endorsement of the teaching that the Earth is flat is to miss the entire point. There is a phrase - straining at a gnat and swallowing a camel. Methinks this is what are you doing in trying to prove that the Bible makes claims that it does not.
When you die, you will know beyond a doubt that God's Word is true and man's vain imagination is vastly over rated and faulty. But it will be too late at that point. But you no doubt have read all about the judgment throne - it's in the Book!
