Well it has no logic that thoughts are in these spirits because their is no brain.<quoted text>
Your second paragraph makes the first invalid. You made my point for me as I said the exact same thing before.
Science lacks here and that is what I said. Science can't tell us what happens after death. It assumes nothing because the brain stops functioning. We believe the soul leaves the body (including all organs) and enters a spirit world until judgement day. Science lacks here. That doesn't mean I have disdain for all science.
Now if you can show a logical way thoughts could exist outside the brain, you might have an actual basis to demand belief.
But as always, religion demands blind faith because it cannot actually show anything concrete.
