Sherlock Holmes and Dr. Watson were always able to solve the crime. But they are characters in fiction.
You, in contrast, have investigated a real mystery. You have seen that not all sources of information are equally reliable. You have seen that some explanations are based more on opinion than on fact. You have seen that nothing replaces your own informed judgement.
You have learned how to find the most accurate information available and how to present your findings to others.
Congratulations!
Even Holmes and Watson would be proud.
