That's a pretty neat theory you have there, but I don't think the reality is as tidy as that! You must want it to be neat because you're human. :)
For a very long time, nobody could figure out how to unify earth-bound mechanics (objects falling to the ground, remaining at rest until pushed, etc) and celestial mechanics (objects moving endlessly in not-quite-circular patterns). Most people were happy with this distinction, as it didn't cause any practical problems and fit well with religious ideas.
As far as I know (but maybe somebody can correct me) there wasn't really a major push to unify the mechanics of earth and space until Newton figured out universal gravitation.
