A childhood belief about getting pregnant

Growing up with religious parents, I got a bit confused about conception. I'd been told that God makes babies, but I'd also been told that parent made them (and that the mother would get pregnant). I had a pretty active imagination and with logic, I reasoned that when a couple decide they want a kid, an angel would fly down and take them up to heaven, where they would meet with God and design a baby. I pictured them going over designs and make blueprints. Afterwards, I believed the angel would take them back to Earth, and God would create the baby from the blueprints and then the baby would appear in the mother's stomach.
Sounds really lame now, but I was truly convinced and it makes me laugh when I remember it now.
