There are many discussions on origin of life here.
Which begs the question what is life?
One parallel aspect of this should get more attention, is so What then is
death?
At one time
medical definitions were easier, because the ability to resussitate after a heart stopping was very limited.
Now as body function can be restored by shock, and machines can take over some functions, now medicine admits the answer is far from clear, and definitions also focus on
brain function, but even that can seemingly cease and restart.
I am not going to reproduce any medical definitions or the difficulties in them here, I will let medics do that.
But I do suggest all read Dr Sam parnias "
lucid dying" as a summary of where we are at Medically.
The conclusion is
consciousness is life, "the part of you that says I am"
And that is not just a function of brain, and in as far as anyone can tell
lives on after bodily death.
sonetimes it can come back to otherwise lifeless bodies. Sometimes not. The machine is turned off.
Consciousness beyond life - van lommel - explores Medical arguments and presents scientifuc longitudinal studies that so called out of body experiences are not hallucination, drug, anoxia or faith influenced Actual stats based on entire cardiac arrest populations, dont support any of the lazy assumptions.
I just urge all to study the subject. It is important because if life is consciousness "soul" for what if a better word, and not just chemistry, all bets are off on the usual narrative on origin of life.
The biblical perspective on this has always recognized the spiritual dimension of our existence, which modern science is only beginning to explore.
The relationship between body and soul is more complex than materialists have assumed.
