Three Quick Questions vs The Enjoyment of Photography

It appears you didn't even read the questions...

• Do f/2.8 1/100 ISO 200 and f/5.6 1/100 ISO 800 have the same exposure?
• If you answer "yes", which is the "correct" exposure? If you answer "no", why are the exposures different?
• Why do we care about exposure at all?

There is a correct and an incorrect answer to the first question.  The second one just asks you to explain your answer, and the third is about the importance of this concept.  None of these answers would "produce this or any other photograph" or any other, for that matter.  They are simply questions for you to answer about one tiny portion of the technical side of photography.
