And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living being.
Genesis 2:7
Adam, which includes Adam's body did not live without spirit within.
Likewise a human body that is growing within it's mothers womb must have a spirit within to be "alive" and grow.
For the body without the spirit is dead. James 2:26
Why would you or anyone else argue with this simple foundational truth?
What are you possible trying to prove by insinuating that a human baby that is alive and growing within it's mothers womb, does not have a spirit?
