Arguments for why an afterlife would be hidden? Maybe I am presupposing that any part of us is nonphysical and therefore it interacts with this nonphysical world. I agree only physical interacts with physical and if any new things come along that interact with physical stuff than it too is defined as physical.
I am interested in logical arguments, perhaps taking big leaps, as to why any such realm if it exists would be hidden.
1). Perhaps there is a deity that hides the living from the dead so we live our lives and don't commit suicide thinking it will give us peace.
2). Maybe the physical world is the minority of things and rarely interacts with the physical world. Like all we know being little more than colors on the EM spectrum.
3). Maybe what we call nonphysical actually is physical but is so subtle that our instruments don't come close to perceiving it.
I'd be happy to hear any interpretations of why an afterlife if it exists is so well hidden. I recently had a close relative pass away and have been in a bit of an existential crisis. I appreciate any concepts on this subject.
