Is my identity truly tied to my brain? You can dismiss this easily enough, as you seem to have done, but what does it mean to begin with?
You claim to have a plausible basis for saying 'it all just ends when the brain stops working'.
But what is it that ends here exactly?
Physical existence? No. The body still exists, and barring major decomposition, still mostly looks like you, and is in many cases still mostly functional. (as demonstrated by organ transplants)
The ripples and squiggles and blobs that can be detected with an MRI; when that ends, I'm not certain but have good reason to believe that there is no more experience.
Could well be true... But there's still no obvious correlation between those things and your 'experience'. You aren't nessesarily 'present' even IF you have verifiable brain activity.
We can only know what another person experiences by what they tell us.
And the dead don't speak.
But it certainly doesn't look like there's anything going on there, now does it?
Nope. But there's still the problem of statistical correlation.
A common issue in the abuse of statistics is to presume correlation implies causation.
In other words, just because two things happen at the same time, it doesn't mean that one causes the other.
I cannot concieve of a method of scientifically verifying subjective reality, which leaves us with the problem that measuring brain activity doesn't actually mean what's measured has any correlation to what the person experiences.
Can I think of scientific experiments that would come
close to answering this?
Actually, yes, I can. (eg... Intentionally messing with someone's brain activity, and seeing if this produces a predictable behaviour from them. - But that would require a quantum leap in our level of knowledge of the human brain.)
But there will always remain a degree of uncertainty.

What will happen after death? Will we go to heaven? Will we born agian? I want to hear what you think.
Nothing happens after you've died. There is no proof that anything
does happen, so why would it?
This is, for example, how we know that the
Big Bang occurred. It has left traces. The
after-life hasn't.
--Xvito,
keeping it excellent.
This line of reasoning, while plausible is also flawed.
It can for instance, be used to argue that the future is non-existent.
Granted, at the end of the day these are all exercises in playing with logic. - The question of death has been one that we have been concerned with for most of our existence.
It's obvious why, because it represents a scary, unknown event, and one which is impossible to avoid.
Everyone wants to know what happens primarily because it will eventually happen to everyone.
Certain religious beliefs don't even relate to what
really happens when you die, but encourage you to 'let go', or to identify with your 'higher self'.
You could take the 'higher self' to literally mean some form of non-physical existence, but you could equally argue that it's a euphemism for thinking about the universe as a whole rather than your own limited identity.
This could start a whole argument in and of itself, but when looked at closely, Buddism comes very close to the seemingly contradictory notion of an athiest religion.
Discounting issues to do with re-incarnation, buddhists talk about reaching enlightenment, and 'nirvana'.
What is 'nirvana'? - It is a state of being in which you are one with everything. But by definition, all seperate identity ceases to exist in such a state.
Thus, you could equally argue that anyone who has reached 'nirvana' no longer actually exist at all.
(it is also interesting to note that at least one buddhist leader has stated that if anything discovered by science conflicts with buddhist teachings, then buddhism is wrong.
Consider what that implies...)
