The direction of current flow is an arbitrary convention and is stated as being from positive to negative. However it doesn't start at one point like water running from a tap. Everything already contains electricity and it all starts moving at the same time in all parts of the circuit as soon as a voltage is applied. So it doesn't matter in which order the resistor and LED are connected. Hope that helps.Russell.
If you take a physics class, current (electrons) will flow from negative to positive.
Electron flow is used when needed, it is just that in electronics it is never needed.
Never say never, what about thermionic valves, and crts. They are still occasionally used!
