> There are definite proofs in mathematics.

We prove theorems, which until proved are referred to as conjectures. But even in mathematics we don't prove theories. E.g., group theory. This is because a) the definition of mathematics theory is not quite the same as scientific theory since mathematics theories are axiomatic, and b) because it's entirely possible that some mathematics theory (e.g., group theory) could eventually be shown to be inconsistent (which is essentially how you disprove a theory in mathematics).
