While no one can say life is preferred over death (to do so would claim knowledge about what comes after death)
We know that we are still energy and matter even after death, that matter and energy does not disappear. It get’s broken down from the structure that is our body and gets restructured into something else.
This something else maybe life, maybe not, or maybe both as some of your remains turn into life within a body of some sort and some are still within dirt.
but the fact that we are alive grants us certain rights; the most basic being the right to stay alive. To threaten someone else's life is to take away their right to life.
The fact something is alive does not give it basic rights; insects, pigs, cows & chickens are alive but they do not have basic rights.
“Basic rights” is not a fact of life; it is a philosophy that is beneficial for over all human freedom of those that matter enough in the world to be protected under that philosophy.
This means you need to have a certain amount of social structure & power within the world to be able to maintain & receive a philosophy of basic rights.
Peace does not place more value on life, rather the value that each individual has right to their own life and to take another's life away is a crime.
Is it a crime when you eat vegetables or the meat of a dead animal; Life is still taken away while each of those things were of their own (individuals).
Why does human life have more rights than these things? Animals still think and they too would rather survive as well as plant life.
Within the world things are given values, the values are not universal (universe itself). We choose and prefer, thus we give higher or lower value to different things.
Which is why there are still countries where the general populous have little to no rights at all. The value of investing all force in those countries is not high enough for the world to truly care. We have other things to do and they mean more pressing than spending the time and resource to change that.
Words speak loudly and ideas are powerful, however action is also speaks volumes.
"But it is non-life that sparks life itself and once we die we become non-life. From non-life we become life." That is nothing more than a philosophical idea.
You talk of misunderstanding and yet you say my idea is nothing more than a philosophical idea?
Philosophical ideas shape the world my friend; it is what allows us to make choices when the choices are not made by nature alone.
