What if..........we are uploaded into a simulated environment, the first task of which is to remove any memories of a previous existence?
Death is merely just an individual upgrade to a new server, birth the beginning.
Going another step further, what of the reason we cry upon birth is due to the realisation that our memories are being wiped and we are aware for just that split second that we will never again see those we have cherished and loved.
Yeah, a lot of smart people in the world think that we live in a simulated reality already. That would be something, eh?
