Interesting thought,
If brain damage can completely alter a persons perception, ability to comprehend, love, form associations, convey emotion, have emotions, think, or interact socially; Then that no doubt means you are your brain, that death is the destruction or dis-function of your brain, that everything you do is a beautifully complex chemical function in your brain. We can conclude that there simply is no room for the soul. If you as a person can be completely changed, and I'm not even talking slight emotional changes. I mean your entire personality and self image can be flipped upside down; you can receive brain damage that makes you question your love, your memories and experiences, your conscious, everything about you and everything that makes you who you perceive yourself as in this instant.
Then what is a soul. If you are beyond any doubt an experimentally proven manifestation of internal brain chemistry, if you are irrefutably completely reliant on your physical being as proven, then that means when the brain dies, you cease to exist. There is no soul that ascends through the clouds to Heaven [or the vast empty darkness that is space], you stop being. Your insignificant self ends on this insignificant planet orbiting an insignificant star of several billion, in one of hundreds of thousands of known Galaxies.
I do not dispute a God, or a Creator, or any such device. I reject human religious institutions and their bullstuff.
You were all raised on poorly written fairy tales.
