Life After Death Is Impossible, Says Scientist

[AFTT47]

I would argue that consciousness doesn't need to survive death to be brought back. In much the same way that turning off a computer wouldn't prevent you from turning it back on.

P.S. I have nothing but respect for the story you shared; and understand the arguments you are making so far.

HELLO MCFLY, try smashing your computer into a million pieces then try to turn it back on.

A sufficiently advanced technology could do exactly that, reproducing the original based on analysis of the pieces. Indeed there is a theory by Leonard Susskind that says information is indestructible. Admittedly, it is way over my head so I am unable to evaluate it. Google it and see what you can make of it.

The point is that you are oversimplifying this. I don't know how much you intuit or understand that there is absolutely NOTHING in known physics that allows for chemical and electrical processes to lead to consciousness. That isn't to say that it can't (because it apparently does) but the mechanism is utterly outside our understanding. Try to understand fire without any inkling of chemistry or the atomic theory of matter. That's where we are with consciousness. With that level of ignorance, it is pure hubris to declare that physics "proves" that consciousness cannot survive the death of the body - especially with outside help.
