Why?

Yes exactly, why!
I agree with you. Children who never ask asking why (each time one level deeper) become scientists!

PS: the original popular reply to the "why" is because of the existence of a universal medium (Lorentz etc.), and the most popular reply today is because of the existence of a physical spacetime (Minskowski etc.). And likely there are numerous variants on those ideas and many other (such as post #16).
