How is a theory an opinion?

A theory can be considered an opinion in that it represents a reasoned explanation or interpretation of phenomena based on available evidence, but it is not definitively proven. Unlike personal opinions, which are subjective and may lack empirical support, scientific theories are developed through rigorous testing and validation. However, since theories can be revised or rejected with new evidence, they can reflect the prevailing consensus or perspective at a given time, similar to an opinion. Thus, while grounded in evidence, theories can still carry an element of interpretation and belief.
