You asked where babies came from, so here's your answer.
–-------------------------------------------------
The human process of procreation is truly magnificent; I shall now explain to you what happens during the entire period of pregnancy, from conception to birth. But first, a little supplemental information:
Once a month, a female is at her most fertile. So, basically, during that time period, she is more likely to get pregnant if she engages in sexual intercourse. This period of time is known as a woman's menstruation cycle, when the lining of the uterus is shed. Basically, a woman's period tells her that she's not pregnant. During this cycle, a woman bleeds out because of the uteran wall's absence (which is why women use things like tampons).
Now for the process. When a man and a woman have sexual intercourse (I'm sure you know how that works), their respective sperm and ovum cells may combine and form a zygote (in other words, fertilization occurs).
The zygote then undergoes a process called mitosis, in which its cells divide and form an embryo in a process known as embryogenesis. All of this happens in about the first two months of pregnancy.
After that, the embryo develops in the uterus, supplied with nutrients by the placenta. An embryo has forty-six chromosomes, twenty-three each from the father and mother. Chromosomes contain genes, things that determine a baby's physical characteristics (hair and eye color, for example).
At about the eight-month mark, the embryo becomes a fetus; during that time it is legally defined as a person and is capable of motion.
Then, comes the birth (you know, with the contractions, and the hospitals, doctors, epidurals, and all that fancy stuff). Basically, the baby travels through the birth canal and out of the vagina, the umbilical cord is cut, and you've got a brand-spanking new human life in your hands.

Hope that's an adequate answer!
