That's a cool belief. So, you believe in it in a more cosmic computer type of premise? It sounds like it with the 0 and 1 type stuff.
So are we the characters in this source's imagination? I can call the source god if you'd like btw. I assume you believe there is only one supreme being worthy of a god title?
Also you left out how this god came to be... i personally concede i don't know. It can either have always been or born, but do you hold either or to be true?
How did we come to be from this god? Or are we from this god?
In regards to the simulation... do you mean a programmed computer type simulation? Or, we are a dream type simulation? Or other of course?
I'll say a brief overview of what i believe so you can ask me questions if you'd like. But like i said, there are two ways i think a god could be born... i'll just pick one for now. I'll use the one where god is everything and has always been. This is the less logical one bc it doesn't follow our logic, but i think if one is going to be true... it's likely the one that's less logical. It's just a hunch in any case.
Even with this god however it was either born or always been. If it was born then everything came into existence when it woke up. It's hard for me to rap my mind around it wasn't born and has always been so i'll go with born. If it was born, it has had eons and/or technically infinite time to evolve. It's likely at its eons age at this point. With that said, it's not truly infinite. It is just eternal in that it can't die. But it's finite up until the end of its imagination which may seem infinite. To me, this fixes both a finite space and infinite space paradox. It's as if we could never die... what would you call your imagination at that point? Infinite or finite? It's a little of both i guess. The implication of this sort of source is that we are all a character that it has imagined over its time. And since it's incorporeal and cannot die... it knows everything at once, therefore everything exists within it. It knows the beginnings and ends of everything. It can piece a human together one atom at a time. It's infinitely intelligent at this point.
The best way to describe how we got here is a sand analogy. This source is correlative to if you think about infinite sand. Everything exists in this sand even without having created it. But, if you want to experience something and make it "real" in a sense, you make say a sandcastle. Now the sandcastle is physical and real i.e. experiencing. Then it crumbles and becomes one with the sea of sand again. As you can see, when it becomes one with the infinite sand... it technically still exists, everything does. But it experiences once it is physical. That's the same with us i believe. In a sea of this source we manifest in the physical to experience. So... that's it with my platform... or at least, one of them. Most the other ones have the same implications in the end anyways.
