Obare Stone of Mt.Gozaisyo,in Japan
The earth was like these two rectangle box-type rocks at first.
Two rectangle box-type rocks coalesced into round shape.
The reason why the rectangle was of golden ratio, is when it gets rounded from that shape of golden ratio, it does not crack easily.
The protruded part from the circle is the Stone gods of four corners .
The two rectangle box-type of Northern Hemisphere and Southern Hemisphere from which four corners were taken out coalesced and they became the round earth.
It was shown by the round rocks in Australia.
