Life after death

I don't conclude that the same thing would happen to a non physical-being, on the contrary, I include the examples of how consciousness is affected when a specific gland or lobe in the brain is damaged to show precisely how consciousness cannot exist in the absence of the brain. Regarding the man with the 7-second memory, though it may not affect his capacity to perceive reality it does enable him to recognise his wife for example, the house he lives in and even who he is and while its true that memory does not impale consciousness completely, affecting the areas of the brain that are responsible for the five senses, certainly do. Consider a dead body without an optic nerve, without temporal or frontal lobes, he could not see, smell, touch or even sense reality in any way; you state that consciousness is linked with the awareness of reality and I ask you, how can there be such awareness, how can a dead being perceive himself in the so called afterlife, when there a no neurological structures to perceive/interact with the elements of the world? that is with light, sound, space etc. If there is no optic nerve he can see no light, if there is no memory he can't have access to his past, if he doesn't have any nerves or neurons, he cannot process light or sound. If you take light, sound, touch, space, time from reality, what is there to be aware of? If memory is gone, together with identity, language and emotion, how can you say that there is an afterlife? You then bring up the Near death experiences but if you compare a real dead person with someone who was clinically dead, the differences are immense. Those people who were clinically dead, had an anatomically intact brain. Sure, that brain might have suffered because of some cardiac problem that stopped blood from reaching neurons, but it's still there, while with a dead person, the brain literally rots. Near death experiences can be explained as follows. When someone dies, not all organs fail simultaneously, they take some time, that's why the brain stem might still be working when the frontal lobes are dead, and because of this, certain parts of the brain might still be perceiving certain elements of reality, might still be producing emotions and thoughts, even though the heart has stopped thereby allowing for some perception in a state when other parts of the brain or other organs have stopped functioning. This is because being clinically dead is not the same as being properly dead. You then speak of doctor Eben Alexander who stated that the part of his brain in charge of thoughts and emotions had shut down but you see, the fact that the frontal lobes or whatever gland or lobe he was referring to, seized to work, doesn't prove anything because all the other areas of his brain were still working. If for example, you shut down my frontal lobes (which regulate thought and emotion) and you leave my Hippocampus intact and also my temporal lobe intact, I will still be able to remember and even speak so again, this fails to prove anything regarding the afterlife because the state in which Eben Alexander was, is completely different from what death is. The type of death I am talking about is one in which all areas of the brain fail to work. Lobotomy is a good example of the point I'm making. If you surgically remove a part of the brain that is associated say with mathematical skill and you leave the rest of the brain undamaged, of course that person is going to lose their ability to do math, but they will be the same in all other branches of emotion and thought. Because in all near death experiences, at least a group of glands and lobes are left undamaged in the brain, perception still occurs. This is rather obvious and your point becomes invalid. You then bring up a study that shows that thoughts still continue when the heart stops. Again, this is due to the fact that even if the heart stops, if some regions of the brain are left intact, they will function for some time before dying thereby it is a reasonable thing to observe. Finally, you speak about "situations that might impact ghosts in a negative way" what does that even mean? I am giving ghosts physical characteristics because that's all that exists in the Universe. Tell me, how can a ghost see without optic nerves? How can he touch something solid without nerves to take that information to the brain? Einstein showed that matter is contained energy. A corpse is metabolised by bacteria and that matter transforms but when that transformation takes place, atoms rearrange themselves to create entirely new things. What room is left for the soul when the matter of the brain becomes food for bacteria or turns into nutrients for the ground?
