When Does Life Begin?

When Does Life Begin? Indisputable scientific fact claims that from the moment of conception (fertilization) there is a living human present.  There is not a single moment from conception (fertilization) to birth when this preborn child is not living, not human, and not a complete individual person.

Science proves that everything that makes us individual – including height, eye color, and skin tone – was all determined at the time of fertilization, thus answering the “When does life begin?” question. The monthly journey in the womb shows exactly why a child inside a woman is just that: a human child who deserves to live. Educated yourself and learn about all the amazing things babies do inside the womb.

Meet Baby Olivia

The Baby Olivia project was created by Live Action to show us how life begins. The images and videos of Baby Olivia depict life in the womb from conception until the end of her gestation.
