The body was once a zygote. Then the Consciousness (soul) gets linked at some stage. The mind and awareness then get build slowly after birth and the personality gets developed.
Not sure I would describe embryological development in such terms, but let's probe this a little more:
The body was once a zygote - not sure I agree with this - certain the body develops from the zygote, just as it does from the oocyte and spermatocyte, but that is subtly different from claiming that the body was once a zygote. Also you should note that most of what develops from the zygote during the early stages of development is not the body at all. More of the cells that develop from the zygote in the early stages produce the extra-embryonic structures, such as umbilical cord, placenta, membranes etc. So it isn't the case that the zygote turns into the body - it also develops into a whole bunch of other stuff.
[/i]Then the Consciousness (soul) gets linked at some stage. The mind and awareness then get build slowly after birth and the personality gets developed.[/i] - So at what point does the person first appear - when the zygote develops of when the soul gets linked (as you describe it). So is the zygote Bob, or does Bob only begin to exist when Bob's soul is linked?
Now I wouldn't use the terminology you do, and your terminology has no place in embryology, but there is an element of reality here. Effectively we ascribe a person and personhood to aspects of our neurological development - hence people being considered dead when they are brain stem dead, regardless of other bodily processes continuing. So surely the earliest point we might consider that the person appears would be when that unique neural identity begins to appear, or has developed to a certain stage. And of course this is way, way later than the zygote stage, which has no neuronal development at all.
