Suppose there are two worlds, “World A” and “World B”. Both worlds look exactly the same. The same persons live in both worlds, say and do and think the same things. Muho is also the same Muho in both worlds. There is only one difference: In “World A” Muho is me, in “World B” Muho is NOT me (you should replace “Muho” for the name of the person who reads this, of course).
Except for myself, nobody could tell “World A” and “World B” apart. They are exactly identical. Even Muho could not tell the difference. Although I do know that I am Muho, Muho has no idea that he is me.
Do I know which world I am living in, A or B? Yes of course, I know it must be “World A”! If this was “World B”, I would not be here (only Muho would be here). For me, only “World A” exists. If I see the world through Muho”s eyes (and I do!), it must be “World A”.

Now I ask myself the first question: Why am I Muho? Muho is the name I carry in “World A”, but I am not really Muho. Muho is not me in “World B”, and I could be anybody else over there (the one who is reading these lines for example).

And now comes the second question: The moment I ask myself why I am Muho, I realize that the question is asked by Muho! But Muho would ask the same question in “World B” as well, although he is not “me” over there! How does Muho know that he is me? How can HE ask the question that is really MY question?

So the final question is: Who is asking this question “Who am I?” Who is asking “Why am I Muho?” Muho can not ask the question, because Muho does not know that he is me. I can not ask the question, because I have no mouth. If I could move Muho’s mouth, he would not ask the question in “World B”. But he does!

So what is this question, where does it come from, who asks it? And is there an answer?
