if memories are never erased, then where is your memory from your past lives and whole 15 billions of existence? If you tell me that they are recorded in a magical place, then the burden of the proof falls on you. Thus it is impossible for you to prove to me that everything that exists has always existed.
Well, you could come at it from the angle of special/general relativity. According to that, there is no such thing as an absolute past or future, since all time statements have to be specified as part of local coordinate systems and relative frames of reference.
Because the speed of light is finite and constant and the universe is expanding exponentially, events that happened billions of years ago could still theoretically be observed somewhere on the far reaches of the universe. I know that this would merely be photons and electromagnetic waves relaying information and wouldn't be the 'actual' events as they took place, but for external observers there is no difference in kind whether you observe an event 'directly' (which is still just about photons being relayed from reverberations in the environment into the eye which then transform into electrical signals via the optic nerve and are then interpreted by neurochemicals to form a mental construct of the 'external world') or a billion years later at the outer edge of the universe.
Lets assume consciousness cannot be deleted, but its access can still be blocked without properly device. However, not having access to consciousness is the same as not existing.
we arrived at a paradox? if I block your conscience it would be the same as you being nothing(coma).
So your consciousness ceased to exist, but It still exists (just isn't accessible anymore.)
It depends what you mean by 'not having access to consciousness'.
What is it that isn't having access to it? If you mean the brain then you are assuming that the only locus of possible experience is the brain, which is an assumption.
If consciousness is independent of the brain, then blocking its access to a particular brain wouldn't stop it existing.
But we don't know if this is the case or not.
Yes, you can be asleep or be in a coma, and this seems to momentarily 'block' consciousness, but I would argue that the 'gap' isn't experienced as nothingness. You just go into a coma, then awake, or go to sleep, maybe dream, then awake. You don't experience the gap as 'nothingness', it's just a momentary interruption in the continuity of conscious experience.
