How do you explain acceleration? Or things like entropy that appear to indicate that the "arrow of time" does exist. Or general relativity / cosmology that clearly shows that your "snapshots of particles" appear different in different frames and there are physical effects that change how time progresses for them all.
> Time is just a way to label snapshots of particle positions in the universe.
You're not saying anything new here, apart from saying that "time isn't real". Is any dimension real? Spacial dimensions are even weirder because they're unlabelled and you can pick and three vectors to define a basis.
