can you clearly state when life begins?
Death is, typically, easier to define,
Until the recent brou-ha-ha began, a baby was considered to have been successfully "born" when he ("/she" being unnecessary modern politically correct terminology since a woman is a female man, since "man" is the species here (when my kids were small my standing joke when they got into this "not man .... since she is a woman" was to ask them whether a "man-eating-shark" would eat a woman) but I digress into nested digressions) drew his first breath.
Lung development and the simple ability to breathe air is generally the limiting factor that decides when a fetus is viable outside the womb, and this normally occurs in the mid-late-20-week period (a close friend was a neo-natal nurse for some years).
Abortion opponents love to crow about when a proto-heart starts to "beat" at some milestone of very few days or weeks and that this is a "sign of life" but if you apply similar standards at the other end of the scale - brain-dead "living" corpse hearts can be kept beating almost indefinitely by simple machines.
If the "life" standard is based on brain activity rather than heart activity, as is often applied to the "brain-dead" at the ends of their lives, then the first "blip" of brain activity shows up in the fetus around that same mid-late-20-week mark that begins the consolidation of lung tissue. But what is a "blip"? What can this "thing" that has never opened its eyes "know" or "feel" or "think" without any real life experiences?
Personally, I regard any argument concerning the "quickening" of "personhood" before lung development and the most rudimentary brain activity to be patently absurd.
Between that point and actual birth, when the development of the fetus has reached higher levels but birth has not yet occurred, then there may be some point of discussion. But ridiculous crap like trying a killer of an 8-month-pregnant woman for 2 murders instead of 1 is just stupid.
