The reproduction was divinely supported to be as effective as possible. Here are the groundrules, as optimistic as I could imagine them being:
The maximum human lifespan is over 120 years old
All women who are between the ages of 13 and 55 have sex once every single week that they do not have their period or are currently pregnant, on average 90% of all potentially pregnant women are pregnant at any given time
Their odds of successful fertilization per attempt are 1 in 3
As soon as a girl turns 13, she begins producing children, no exceptions and she stays active producing children until the age of 55
There is no infant mortality
There are no deaths during childbirth
Death rates in general are dramatically lower than in modern times
My goal in this simulation was to see what would happen if childbearing rates were accelerated enough to account for the populations necessary for the Egyptian, Mesopotamian and Chinese cultures.
I've run this program a bunch of times and I know that it is relatively flawed, but wherever possible I have tried to err towards miraculous reproduction rates, not to simulate known population growth rates. After 180 years from the Flood, at approximately the time period of the Tower of Babel, the population of the Earth the app comes up with numbers in the following ballpark (these are from a specific run, random factors lead to slightly different numbers with each run through):
- Population of the Earth: 61,162
Hey, not bad, I thought when I ran it the first time. A decent seed population for Babel, and only about 500 years after the claimed Egyptian dates... Then, I decided to break it down and I found something fascinating... They're almost all children under the age of 12:
Girls under 12: 25,989
Boys under 12: 21,446
