The Theory of a Flat Earth (a theory) explains the mechanism by which the Flat Earth (a fact) takes place.
The Theory of an Earth centered solar system (a theory) explains the mechanism by which the Earth at the center of the solar system (a fact) takes place.
Your theories cannot be supported by the evidence. It is observable that the Earth is not flat, nor is it the center of the solar system.
Actually, NOT a theory. It has been falsified. UCANSEE that, right?
