jmeyer - Centuries before Pythagors, the Bible recorded that the earth is round at Isaiah 40:22:<br /><br />(Isaiah 40:21-22) "There is One who is dwelling above the circle of the earth, the dwellers in which are as grasshoppers, the One who is stretching out the heavens just as a fine gauze, who spreads them out like a tent in which to dwell,"<br /><br />"Circle" is a translation of the Hebrew word "hhug" which means circle in 2 dimensions and sphere in 3 dimensions. <br /><br />Isaiah was written about 732 BCE (=BC).<br /><br />Many centuries earlier than that Moses wrote that the terminator on earth is a circle, which can only be true if the earth is a sphere:<br /><br />(Job 26:10) "He has described a circle upon the face of the waters, To where light ends in darkness."<br /><br />That was written about 1513 BCE, about 1,000 years before Pythagoras.<br /><br />Interestingly, earth is mostly water, and when light first reached earth's surface, earth was totally covered with water (see Genesis 1:2)
