I mean correct me if im wrong but in the text you referenced it suggests that eternalism, by definition, corresponds to a past, future and present and seems to only reference low 2-C stcs. Consdering that. the OP kind of already debunks eternalism for me, since the time in the OW doesnt follow past present future. and the time does not govern 3 dimensional space but rather 4 dimensional space. A bit more on this below
I mean im leaning towards the idea that time here doesnt govern the otherworld. from the evidence it can only be justifiably inferred that time is a hypertimeline. Anything beyond that is just assumptions or unjustified extrapolation which is what i have a problem with.
i agree but it is what it is, my argument already assumes 5D to be the case so eh.
