If I could rename the Earth, its name would not be its definition. It would derive from an adjective. An adjective that would express all that the Earth is; in some parts, simplicity. In others, difficulty. In other parts, love, and in others, hate.
Although the name comes from the common and sturdy foundation, it would be more explanatory to name it based on human creations that developed the planet. It would not base itself on certain people, places, or objects, but simply the emotion the planet exudes from the surface to the exosphere.
