gravity is not 'owned' by globe earth, it only becomes globe earth in it composition as a 'law' within the theory.
it obviously something is doing it. the why is in doubt, and is 'claimed' by the globe earthers to prove their position, i say you are overreaching.
Globe earth fits the measured effects of gravity and accurately predicts its behavior. What do you have?
same thing, I just don't assume it denotes a globe.
