Well, agents pretty much tend to be complicated things that need to be explained in terms of more basic things. So if some sort of agent in some sense deliberately created our world... that agent still wouldn't be the most fundamental thing, it would need to be explained in terms of more basic principles. Somewhere along the line there'd have to be "simple math" or such. (Even if somehow you could have an infinite hierarchy of agents, then the basic math type explanation would have to explain/predict the hierarchy of agents.)

As far as "whatever translates to immortal soul", we pretty much mostly know that. We don't know the details of how it works, but we know that it amounts to physical/computational processes in the brain". (Less immortal than we'd like, but that's what we need to do something about.)

Even if an agenty process created our world, how does that alter this fact? It may influence some details (like if there is such an agenty process, we need to work out just how much of a threat that process/being is (and various other details) and thus deal with it accordingly, of course).

However, does our world ultimately look like it's primarily generated via agenty processes or by mindless processes?
