we don't know why or how there is electric charge (and their related fields), we just know that there is electric charge; it's one of the properties of the universe; same with gravity. We have uncovered mathematical laws of charge and and their relationship (via div, grad, curl and all that) to magnetic fields, but we don't know how or why, just what is.
"A map is not the territory it represents, but, if correct, it has a similar structure to the territory, which accounts for its usefulness." — Alfred Korzybski, Science and Sanity
You are confusing conceptual models of reality with reality itself.
The Scientific Method is used to construct an accurate, reliable, self-consistent, non-arbitrary representation of the world, which are models.
QED is one of the most stringently tested theories in physics. But it is a model and will never be proven as 'True', we just get more confident in he model after it passes test after test, after test, after test.
But it is still just the map and not the territory itself.

Feynman knew this well:

Feynman was awhile ago.
But which Fenyman?
