The Soul is a purely religious concept, hence my first post asking for what religion the OP was curious about. Once we set on a particular religion, we can agree to terms and discuss.
Alternatively, though, there is another valid non-religious discussion that might be what the OP intended which is: At which point after conception does the concept of human life apply to the gestating life?
Somewhere between “egg and spermatozoa side by side” and “Dad, can I have the car tonight?” a human life starts. When exactly does that happen?

Good questions. We’ve had this discussion several times before, and if you mean what is the scientific answer, even that can depend.
There are any number of arbtrary goal posts than cen be set up, scientifically:
Fertilization: The unique DNA of an individual has been formed.
Brain function: We recognize brain activity as being crucial to human life, just as we do to human death. Of course, there’s “brain function” and then there’s “brain function”.
**
Transition from embryo to fetus**: The major organs and structures have formed.
Measurable brain waves: See above, brain function.
Viability outside the womb: For obvious reasons.
Birth: Also for obvious reasons.
Those are only a partial list of pre-birth milestones, btw.
Then it gets sticky. A human baby is, compared to other primates, born prematurely. It’s not until we’re several months old that we start to take on characteristics that distinguish us from other primates. And we don’t really recognize ourselves as individuals until we’re about 2 years old.
If we look at it from a scientific and an ethical standpoint, we need to ask ourselves what does science tell us about human development and what does ethics tell us about the kind of society we want to live in. I’d be willing, from a scientific standpoint, to say that a newborn isn’t “really” human, but I think our society would be damaged signficantly if we leaglized infanticide.
I’ve come to the conclusion, personally, that we can allow viability outside the womb (minus a few weeks, to be safe) to be the criteria. Killing a fetus that would almost certainly survive outside the womb isn’t much different, in my mind, from killing a newborn (especially a prematurely born baby). Unless the helath of the mother is compromised, it seems not to be too much to ask that she carry the fetus a few more months to term. Few, if any, women only learn that they are pregnant at that stage, so they’ve had time to consider the options.
