Consider an EM field. Do you think there is some daemon grinding out complex exponentials as it propagates? In reality some spinny thing is rotating and moving through space. What those terms actually are isn't precisely known but the phenomenon closely fits a mathematical model we can elaborate on to do useful things. That doesn't mean it's how reality works.
Though it could be how reality works. Maths things like pi don't seem to need daemons calculating it for it to have a value. And perhaps likewise EM fields.
