NOT TALKING ABOUT ABORTION.....
Legally, the child has life, when he or she takes their first breath outside of the womb....if they do not take that first breath, with or without medical machinery help, the baby is considered stillborn....born dead.
Scientifically the human or any species living fertilized egg, yes from Conception, it is a species being formed in to an individual and is made up of living cells or even living organs in time....
with humans, it's being formed in to a person....
With Adam, God formed Adam...but Adam did not have life until God breathed life in to him, not until the first breath taken, did Adam have LIFE.
I think when a foetus in the womb is developed enough that they can take their first breath and survive outside of the womb with or without medical assistance, they have life...I think foetuses can survive without mom, outside of the womb, at around 22 weeks of development now with medical improvements, out of the 39 weeks of full pregnancy.
