Zooming in further: if these are genuine memories, where and in what form were they stored between biological deaths? What is the medium of this storage? If consciousness is a product of the brain, it dies with it. If it's
non-local, how does it interface with a new, distinct brain to produce specific, sensorimotor recollections? The
problem isn't just proving they exist, but explaining the how in a way that doesn't
break known neuroscience.
Example: "The boy's vivid 'memory' of dying as a pilot involved the specific smell of burning engine
oil. The hard problem of past life memories: even if we accept a
soul, how does a non-physical entity 'remember' a purely physical sensation like smell, and then encode that memory into the new,
different neural architecture of a toddler's brain?"
