Quantum entanglement indicates that at least at some spacetime level instantaneous communication can happen.

Either that, or all events are somehow super-determined.

When tasked to explain it to someone I use a different approach, referencing the three variable epxressions of dimension Time as related/connected to the three variable epxressions of dimension Space. It all got started when Time was a non-variable (moment) and Space was a non-variable (point). Things get complicated soon thereafter ... inflation happened before matter existed, but when matter aapeared, Time of the background took over the Time contained in the matter.
