The Dead

I have always had these thoughts since i was young.
I would sit on an open ground and stare up at the stars and think, 'Why do people say that the dead become stars? Doesn't our body work due to  cells. Different cells contain different functions. Brains think based on what they see, hear, smell, eat and touch. So where does the concept of soul come in?'

I still think a lot about this 'soul' when I look up at the starry night skies.
Do you imagine, that maybe your life is a diary written by someone and you are just acting in it? May be all your decisions have been taken by someone else and you are just enacting it without you knowing it.

Speaking of the title, why are people afraid of death?
Is it because after that is unknown?
Maybe the 'soul' is reborn into a different child somewhere.
So does the soul contain your lives memories?
Where is it reborn? In the same country or in different possible galaxy?
When is it reborn? Far ahead in the future or so far back that you travel by carriages.

Does the body just perish? Decay into bones and ash?
What if we well preserve the brain, keep it working and transplant it.....would you be reborn? Would the body's memory work for you?

Do people remember their deaths?
