Here's what Eugene Scott wrote about that in Evolution Vs Creation, 2005, University of California Press, page 14:
'The word "theory" is perhaps the most misunderstood word in science. In every day usage, the synonym of theory is "guess" or "hunch". Yet according to the National Academy of Science, a theory is defined as "a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and hypotheses" (National Academy of Sciences 1998). To explain something scientifically requires an interconnected combination of laws, tested hypotheses, and other theories. This reliance upon inferential reasoning is the hallmark of theorizing.
Many high school (and even , unfortunately, some college) textbooks describe theories as tested hypotheses, as if a hypothesis that is confirmed is somehow promoted to a theory, and a really, really good theory gets crowned as a law. Unfortunately, this is not how scientists use these terms, but most people are not scientists and scientists have not done a very good job of communicating the meanings of these to students and the general public.'
The way folks talk about evolution as if it were "only" a theory makes one suspect they are attempting to do away with evolution by analysis of the word "theory" instead of analysis of evolution itself. Surely nobody in this forum will do such a silly thing . . . right?
