Euclidean geometry is not a theory; it's a set of axioms from which 
theorems (not theories!) can be derived. The statement "Euclidean 
geometry accurately models the world" is a theory, and it's also easily 
refutable. But that doesn't falsify Euclidean geometry itself.

You're seriously muddling the concepts.
