Is space empty when it contains fields. How is matter different from

The more I learn about fields the more confused I am about them. Do the
particles create the fields or do the fields create the particles? Does
that question even make sense? What IS a field?

I do tell my students that an electric field (for example) is a real
thing, just as real as the charged particle that creates it. But
thankfully, no one has asked me to elaborate on "create."

A field is the current model for working with observations involving
action at a distance, with no "visible means of support".
