Worried there might be an afterlife

[Iroscato]

So many guessing.
A mountain of guessing with no evidence of whatsoever.
How would you know that life end up with the physical death?  

Just saw this.
How do I know? I don't. But common sense and the utter lack of empirical evidence to suggest otherwise leads me to strongly believe that once the brain dies, that's it. The brain is everything you are, it has every piece of information encoded inside it that makes you 'you'. Under general anesthetic, you do not dream, you have no conscious awareness whatsoever. For all intents and purposes, you cease to exist as a conscious enitity. I posit that death is like that, except that it lasts forever rather than minutes or hours.
That is what death is to me - an instantaneous eternity.
