I feel the Abrahamic afterlife is disprovable... The Abrahamic afterlife is centered around the idea of the ego "self" persisting for eternity in heaven.

It is possible to experience the complete temporary cessation of self by inhaling some weird chemicals (an experience I have been through many times)... The self is so fragile that it can be wiped out by messing with brain chemistry while the brain is still in tact and alive.

The idea then, that it can permanently remain and survive the actual DESTRUCTION of the brain seems almost disproven.

The proposal then, is that I can only experience the total death of self while, ironically, alive? And that I will be more locked in to my "self" after my body and brain are destroyed?

I don't feel it can be reconciled at all...
