Do the laws of physics of the outermost reality allow for a god-level being to exist?
When a god-level being comes into existence, do we cease to have independent trials? This could mean a supreme being helping to nurture our growth to godhood, or this could mean a supreme being preventing others from becoming that powerful. Or some other thing.
Also, no matter where exist in the outermost dimension of time, the number of time intervals (trial periods) preceding that moment will be infinite. Thus, if a self-sustaining supreme being did come into existence, the moment of its emergence will always lie in the past. I am not sure if this is the same thing as having always existed, but it is certainly a very similar concept.
