There is a life definition of life according to Father of humanbeings, Adam.
After Kabyl killed the Habyl, after Adam has learned, says its to Eva:
"Habyl is dead".
Eva asks:
"What is dying?"
Adam replies:
"He is not eating, not talking, *not breathing anymore" (I'm not sure if maybe walking, may be breathing)
Then Eva cries.
This is meanwhile the first crying of human beings. Inother say, after Habyl dies, Adam was not cried, but after his mother has learned, she has cried.
There is a preverb in Turkey: "if one cries, only his/her mother feels his/her pain truly".
Anyways.
According to these definition, life is at least
a) eating
b) talking
c) breathening
If one of these exists, so there is a life here. If any of them are not exist so no life.
But I'm not sure of breath. I've searched for source but could not found. It has to be somewhere in any religinal texts.
