Here at the edge of the lunar eclipse shadows cast by the Earth to the Moon, it is always an arc of a circle, and the only body capable of providing a shadow at any position and direction of the light source, there is a ball. Can think?
I can prove beyond a reasonable doubt that the Earth is not in motion using a combination of established and replicated scientific experiments. The spinning ball is model has been broken and you're clinging onto a corpse of an idea.
A reasonable conclusion here is that there's a 3rd celestial body in between the plane of the Earth and the Moon.
Keep your reasonable doubt. All kinds of people have proven conclusively that the earth is a spinning globe in motion with the rest of the spinning-globe bodies throughout the universe.
The Sagnac Experiment shows there's an aether with irrefutable empirical proof. With an aether the Michelson & Morley Experiment proves the Earth is motionless and Airy's Failure Experiment corroborates these results.
You've got no room left to wiggle worm.
