Consciousness prove using nothingness and reencarnation basically is about nothingness being an non physical entity, therefore anything worldy that resembles nothingness is not physical even if it is in the world.
Then the question of how something not physical can came up in the world if everything involving worldy experience seems physically could be answered by a gate between mind theory of nothingness and world, that gate is what I and some people describe as consciousness.
One way I thought of how can nothingness be a part of a world is by thinking of reencarnation.
I argue reencarnation as the probability of existence after death based on the actual existence after being. I put death and being born with similar connotations because both resemble me of nothingness. This resemblance with nothing is the argument of a non physical prove on world that is created in the mind and tied with consciousness.
Let me know if I can clarify anything.
