Good post Minnie. If this is actually your belief then I think we have something in common. My position is rather simple. If life ends when a person takes their last breath then by logic it must begin when a person takes their first breath. However I still struggle with the fact that a fetus is breathing while in the womb. Definitely not air, but still filling it's lungs for the moment when it's birthed.
Actually the lungs are filled with fluid when it is birthed. From the flowing:
At birth, the baby's lungs are filled with fluid. They are not inflated. The baby takes the first breath within about 10 seconds after delivery. This breath sounds like a gasp, as the newborn's central nervous system reacts to the sudden change in temperature and environment.
Once the baby takes the first breath, a number of changes occur in the infant's lungs and circulatory system:
Increased oxygen in the lungs causes a decrease in blood flow resistance to the lungs.
Blood flow resistance of the baby's blood vessels also increases.
Fluid drains or is absorbed from the respiratory system.
The lungs inflate and begin working on their own, moving oxygen into the bloodstream and removing carbon dioxide by breathing out (exhalation).

Also it is the woman’s placenta not the lungs of the of the fetus that does the exchange of oxygen and carbon dioxide while inside the womb.
The mother's placenta helps the baby "breathe" while it is growing in the womb.
Oxygen and carbon dioxide flow through the blood in the placenta. Most of it goes to the heart and flows through the baby's body.
