materialists definition of "exists"

Since materialists say that massless and volumeless (no volume) particles exist, what does it mean to say that something exists physically?

You can see massless particle rather as an event/phenomenon/act/effect: something somewhere, sometime happens... for example due to some (over) strong physical fileld or due to (too) weak bindings... They say: It has been a photon (for example)

Are you saying that when physicists say that a particle has no mass or volume, they are actually saying that a field surrounds such a point?
In other words, for a physicist particles are not particles but the imaginary point at the center of a field?

Consider a boat with a man on the sea. At one moment one of stronger wave hit the system (boat-man) so that such system decay into two parts: boat with opposite "spin" and a man
We can say: It was an interaction of two partices "phlonon" and a boat-man.
Btw: I consider elemetary particle as a structural defect in regular structure of physical space that mostly generates strain (field) around itself
