Years ago I used to be very interested in Mormonism, though that was when I was an evangelical Christian and my main interest was in converting them. But I learned quite a lot about them and even attended a Mormon church for a while (incognito, as it were).
One thing I learned was that, according to Mormon theology, every human soul born on earth was originally procreated in heaven by God the Father having sex with one of His many wives, who then gave birth to a “spirit child,” which in turn had to be born into a physical body in order to progress into eventual godhood. Considering that the current birth rate is something like 200,000 per day, that’s a whole heaping helping of heavenly humping!
