"Fundamentally determistic" but not fully deterministic? What is the meaning behind that first adjective?
Fully deterministic would indicate hard determinism and no free will. Fundamentally deterministic would indicate that determinism is the foundation of the nature of our existence, and allows limited free will as in the philosophy of compatibilism.
The "macro universe" has not been determined beyond all reasonable doubt to be deterministic.
Yes it has. There is no objectively falsifiable evidence that indicates otherwise. Again . . .
Pretty much all the scientific research and development of theories and hypothesis have demonstrated that our universe has predicable natural laws that are fundamentally deterministic even in the predictable nature of the Quantum World.
You have failed to provide any objective verifiable evidence that our physical existence is not deterministic,
