If we examine the hard problem of consciousness from a scientific standpoint, shouldn't it be true that a material body cannot shelter an immaterial spirit?

The material body changes all the time, and scientists know what each part of the brain is responsible for, you cannot hear without the auditory regions of the brain functioning, and you cannot move without the motor cortex, and you cannot see without the lobes in the back of the brain. That's why injuries to the back of the head can make a man blind in rare occasions.

Even your thoughts, and every thing about you we know where these things come from, regions of the brain. But the brain is not unchanging, it warps overtime and the "soul" changes with it accordingly. We can change somebody's personality and entire "soul" with a little brain surgery. We can physically alter the soul. Who is to say then, that it's (the soul's) not just a subjective representation of the combination of all physical processes in the brain?

And if that's the case, then the "soul" finds no identity within a man's material form, no, rather, the brain generates the soul, and thereby proving that when you die, you simply become somebody else, because you are all people at once, even now, and each one of you is experiencing your life simultaneously. You are all men at once but each of your incarnations is unwitting of the others.
