The whole world spins on this.

  1. Literally.
    The electron in a Hydrogen atom ‘dawdles’ around the proton because its negative electrical charge ‘recognizes’ the positive one and is attracted to it. Furthermore, the Moon revolves around the Earth because their masses ‘recognize’ each-other as such and, ‘hence’, are subjected to a mutual attraction.
  2. Factually.
    Things are a little more complicated at this level.
    For something which exists to become a ‘fact’, that something must be first noticed by somebody. Until then it exists in ‘total darkness’. We cannot even say it doesn’t exist, simply because we are not aware of the possibility of its existence.
    In this sense, the Moon had started to revolve around the Earth only ‘after’ we had recognized the pattern of its movement.
  3. Teleologically.
    Otherwise said, for as long as it fits our purposes AND/OR our understanding of the world.
    The Sun and the Earth had pulled at each other since the start of time. For only as long as we had been believing in Newton’s theory about gravitation, of course…
    And, at first, we had been convinced that it was the Sun who was speeding around the (flat?!?) Earth!
    Despite the many proto-scientists who did their best to open our eyes.
