@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
retrodiction is exactly analogous to our
prediction. 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 and
thingers are co-existent and co-extensive.
