Scientific theory is only an opinion?
In a Colloquial sense, yes, in common day speech, a theory is simply an educated opinion, however, in a scientific context, A theory is the highest degree of proof available, in science, a theory is the combination of all available data on a particular matter that allows a person to establish knowledge on a preexistent hypothesis. To be a theory, something must not contradict existing knowledge, it must have faced scrutiny and survived, and must have made apt predictions that have been confirmed by rigorous experimentation.

This statement is incorrect. You must have evidence to support any opinion you give - whether it is a paper, a speech, a conversation, or just a paragraph! The way that you prove what you are saying is by giving evidence to support it.
Why is a hypothesis important even if evidence fails to support it?
When working through an idea using the rules of the scientific method, you first must start out with a statement of what you hope to find or prove. It's the "What I want to find" to the Method & Methodologies' "How I am going to find it." Even if the data or evidence fail(s) to support it, you still need the statement of purpose. If the statement and results are not a good fit, then the statement (hypothesis) can be revised or thrown out.
