Why two sets? (updated)

Jr. was having some fun with an english workbook she got as a gift. This is now our usual routine in the evenings.

Today she had to answer a question which was :

_______ went to swim.

the three choices were

Him
I
i

She figured out that Him was wrong as soon as she read that option.

Then she looked at me and asked me a very profound question.

"Daddy, why do we need two set of letters with all this uppercase and lowercase stuff? Why can't we have just all uppercase or all lowercase?"

I really do not have an answer for that one! Why? Why?

Now, I have a question for my parents!

Was I smart or lazy enough to ask that question when I was learning english? and if I did, were you proud of me?

Why do we need two sets of letters people? Answer me!
