The sperm cell finds the egg and penetrates the outer layer to fuse with the nucleus of the egg cell to form what is called a zygote. They become a ball of multiplying cells: 2,4,8,16,32,64. The zygote develops into an embryo, the embryo develops into a fetus and when it emerges from the woman's body is called infant. When is the soul entered into the body?
