How did ancient perspective differentiate Earth from other planets?

Other planets were *wanderers*; Earth was the fixed center/stage.

The crucial difference in ancient perception lay in mobility and centrality. The other planets were recognized because they were 'wanderers,' visible as points of light that moved predictably against the seemingly fixed tapestry of stars. This movement necessitated assigning them divine governance. In contrast, Earth was the stationary, known entity; it was the ground beneath the observers, the immovable stage upon which the heavenly observations took place. Because it was so fundamental and present—the environment itself—it was not perceived as a distant celestial body needing a divine appellation, thus resulting in its unique naming path based on material properties rather than mythology.
