Those "why" questions are exactly what math and science do not answer (:
Not saying that philosophy or religion is particularly good at answering them either, but that's more the domain you're getting into, I think.
Brief excerpt from this Feynman interview[1]
"Say pop, I noticed something: when I pull the wagon, the ball rolls to
the back ... and when I'm pulling along and I suddenly stop, the ball
rolls to the *front* of the wagon." And I said: "why is that?"
And he said: "That, nobody knows. But the general principle is that things
that are moving tend to keep on moving, and things that are standing still
tend to stand still... This tendency is called "inertia," but nobody knows
why it is true."
