Lovely how you pick parts again. Explain the predictability.
What about it? The charts and equations for most RE phenomena are equally applicable to the Flat Earth model. On the tides for example; the equation which predicts the water level is a short algebraic equation which predicts the water level based on historic charts and tables along with the present time of the year and time of the day. There is nothing in the equations which suggests that the tides are caused by any particular phenomena. It's a fact that any recurring phenomena which comes in patterns can be predicted with an equation.
The same fact goes for the Lunar Eclipse and the variations of the pendulum. There is nothing behind the predictive equations which gives us a mechanism for the phenomena. Those same tables and equations are equally applicable to a system which gives an alternative explanation for the phenomena.
Based on historic tables and charts I can predict that tomorrow's high tide at a location will reach a certain height. My prediction does not tell me HOW the tide was created, or anything which gives me the precise mechanism behind the tide's creation. Based on my equation I can attribute a number of explanations to the true and underlying mechanisms for the phenomena. A predictive equation is just a predictive equation and nothing more.
