@Ding an Sich,
What you are failing to see is that both "time" and "events" are human
psychological constructs. They have no meaning outside the disposition of observers to order their album of snapshots of inter-relationships. You are thinking of a seeing a hypothetical moon snapshot that you would inductively place at some front end of your album. But that
is not what the import of "the existence of an ancient moon" is about....it is about how such a postulate accounts for current
events like the geomorphology of shorelines etc. Our retro
diction is exactly analogous to our pre
diction. It is an attempt to establish causal links between events in order to anticipate and gain a measure of control over them. But such "events" are ultimately about our species specific
relationships with the world. From the point of view of a blind species the is
no "moon" and never will be. From the point of view of a dog, promising to take it for a walk in an hour
will not stop it scratching at the door it immediately hears the word "walk", because it has no concept of time.
Who is to say what future paradigms may bring ? In a thousand years time (if we survive) people may be laughing at the idea that celestial bodies are separate entities, just like we laugh now at the idea of separate Morning and Evening stars. In QED (quantum electro-dynamics) we already postulate particles which travel backwards in time, or that simultaneously occupy different locations in space. In a thousand years, what will constitute "an event" ? What will constitute "time" ? What will constitute "an entity". Will the photo album be linear ?
I repeat, things
are co-existent and co-extensive.
