Doer, when the brain dies so does the organic material that sends the electrical signals to our brains to keep our memories from ceasing to exist. If our memories "die" when our brains do, wound that not also mean that "we" die too, if memory is what makes us, US?
Either way, this does not change the fact that science is what we can actually experience in reality with our sense perceptions (the closest we can get to what is real) and religion is what we experience within our imagination without basis in this reality (the closest we can get to what we WANT to be real).
On a side note, i find it interesting that when people have near death experiences, it always ends in what they as an individual are emotionally attached to, or are emotionally afraid of.
