what about people who have been long forgotten? they dont exist, their synaptic pathways have long since been disolved and their brain tissue no longer exists. and im sure that if were talking about a nobody from 2k years ago that nobody remembers them. so therefore they dont exist now, but they did.




you can't seperate time and space, if you were to go back in time you would just become yourself exactly as you were at the point you went back to.
