I don't use the word 'reality' the same way that you seem to. I don't think of my own subjectivity as my own personal 'reality'. I'm not God and I don't possess a 'reality' of my own. I think that there's a single reality in which all of us are embedded.
But does that not negate the argument of creation of reality and then become embedded as part of this reality after the fact of Creation?
I have no fundamental problem with intra universal communication of a kind, but how would that work before the universe was even created., other than through Mathematics.
Consider (assuming) that god must have been sentient. motivated, and all powerful, let's follow the history of Creation.
a) "let there be light" is a command, but a command to what and by whom? OK, god.
So there was light, then god created the heavens and as his crowning achievement he created the earth and everything on it (paradise). But god needed someone who could truly appreciate his wonderful work and he created man and woman and this worked just fine for awhile.
Then god had a quarrel with one of his angels and as punishment god looked around for a suitable place to shield the rest of the universe from this disobedient angel. Where to put him? In a supernova? Maybe a Black Hole would be a good prison?
But no, god sent the devil (evil) to his one true masterpiece, paradise, to tempt mankind (made in his image). The plan worked perfectly and after the devil tempted innocent mankind (god's crowning achievement), turning the earth into the hell-hole we are witnessing today.
Does any of this make sense as an attribute of a loving god who created the miracke of earth and mankind and then purposefully broke it, as punishment for one of his own kind? That sounds not only unfair to me, but reminds me of an "abusive father".
And I am to believe ANY of that, without question?
From the psychological viewpoint of the intent of scripture, clearly describing "god's will", which might be called "aversion therapy", if man was innocent before being tempted by the devil (who somehow was able to disobey god's will), why punish mankind by dumping the devil on earth?
At best this would be unjust, reasonably this would be "indifference, at worst an intentional act of introducing evil into what once was paradise. Then after god's devil corrupted mankind, makind itself was banned from paradise?
What was god's motive in all these chinanigans? Just for fun?
