A fellow member pointed out to me that nobody knows the shape of the earth as it stands. The circle theory hasn't been entirely proven, so how do we know it's not an octagon? In the Bible, God rested on the 7th day, but what about the 8th day? Octagons are commonly referred to, in the Hindu bible, as godly figures and symbols of nature and purity. Ancient Chinese explorers throughout the Han dynasty used octagonal maps to separate territories and are largely accurate to this day. Before the Greek gods were influenced by the Romans, there were only the 8 powerful deities. These deities were commonly associated into one worldy figure, each making up a side of the octagon.
I don't know, but it seems plausible to me. It's a serious consideration in my mind.
