This world was never meant to be a world in which that which is different was meant to be defined as one is good and one is bad.  The Earth says their body is a perfect reflection of how we were suppose to translate opposites once we transitioned into our human bodies.  Within the Earth it was written how to translate opposites.  We see their function was to work as a whole, as One.

This is a world of duality, pairs of opposites working as One.  We have solid land mass and we have water, 2 opposites who work as One

We have trees, roots that travel into the Earth with a function much different than the outer tree.  They are 2 opposites that work as One.
