There is an alternate theory that Columbus called the people of the New World "Indios" or children of god because of their peacefulness and kindness. The just the kind of people the Europeans took great delight in murdering, raping and pillaging.

The flat earth had been rejected for centuries by the times of Columbus. The Greeks had long ago proven it was round. If anyone used the bible to claim it was flat, it is only proof that the bible is useless. If you're not already on the right track before you read it, it won't set you on the right track, it will only reinforce whatever it is that you currently believe and since no one can have every right answer then neither can the bible. Case closed on that.
