I can't help but notice your failure to cite the scripture that describes the earth as a sphere. Perhaps that's because there isn't one and you're lying for the baby Jesus again.The earth's shape is a spheroid
Although the earth's shape is technically an ellipsoid, its major and minor axes do not vary greatly. In fact, its shape is so close to a sphere that it is often called a spheroid rather than an ellipsoid.
Although a spheroid best represents the earth's shape, the earth is sometimes treated as a sphere to make mathematical calculations easier.
[The Bible teaches the earth is a sphere too, but the Bible doesn't waste as much time babbling on and on about it as scientists do. The Bible keeps things direct and to the point, not wasting time with endless chatter about these small matters.]
Given the Bible's ratio for Pi, this is hardly surprising. Your god has some pretty funny ideas about what a sphere is.
