Genesis 2:7 "And the Lord God formed man of the dust of the ground, and breathed into his nostrilsthe breath of life; and man became a living being." The first human life did not begin with the first two particles of dust that God assembled. It didn't even begin when all of the particles of dust were assembled. It began with the first breath.
This is far from the only passage that suggests that life begins with the first breath rather than conception:
-Job 33:4 "The Spirit of God has made me, and the breath of the Almighty gives me life."
-Ezekiel 37:5 "This is what the Sovereign LORD says to these bones: I will make breath enter you, and you will come to life."
In fact both the Hebrew and Greek words for "soul" are synonymous with "breath"
-Ruach: Strong's Hebrew: 7307. ?????? (ruach) -- breath, wind, spirit
-Nephesh: Strong's Hebrew: 5315. ??????? (nephesh) -- a soul, living being, life, self, person, desire, passion, appetite, emotion
-Pneuma: Strong's Greek: 4151. ?????? (pneuma) -- wind, spirit
Clearly the Biblically supported position is that life begins not at conception but with the first breath.
Furthermore. the Bible gives explicit instructions on how to force a woman to abort a pregnancy that results from an adulterous relationship:
Numbers 5:11 "Then the LORD said to Moses, 12 “Speak to the Israelites and say to them: ‘If a man’s wife goes astray and is unfaithful to him 13 so that another man has sexual relations with her...
...may the LORD cause you to become a curse among your people when he makes your womb miscarry and your abdomen swell. 22 May this water that brings a curse enter your body so that your abdomen swells or your womb miscarries.”
“‘Then the woman is to say, “Amen. So be it.”
...If she has made herself impure and been unfaithful to her husband, this will be the result: When she is made to drink the water that brings a curse and causes bitter suffering, it will enter her, her abdomen will swell and her womb will miscarry
Question for debate: Is there any sort of biblical support for the notion that life begins at conception?
