I understand your point
It would really be peaceful if it's a void after death
But I am scared if I may reincarnate or other possibilities including religious ones
Do you remember being a soul before you were born ?
Nobody remembers this.
Also, if there is such thing as an eternal soul, then surely babies would be super-intelligent because they would be all knowing.
A babies self, or ego, is only formed through the development of the brain and learning processes.
Consciousness is purely a biochemical reaction in the brain and the concept of a soul comes mainly from religion.
Even people who have supposedly had near-death experiences have never truly had one because they have not been officially brain dead because they have been resuscitated.
I can understand being scared, it's only natural.
