So, in a novel a buddy and I are working on, the gods created mankind 3000 years ago, their last act before they perished. The gods left behind several books containing all the knowledge a society would need to grow (agriculture, navigation, domestication of animals, crafting, fire, language, etc.), as well as an enchantment placed upon them that anyone that viewed them would instantly know how to read them.
That aside, we have one civilization that ended up on a peninsula to the far south of the continent. They have a massive desert to their north and nowhere else to go. This peninsula is approximately 58,000 sq km of livable land.
So, the question, assuming they began with a population of about 100 people, what would their population be 3000 years later?
We can assume they always have enough food and water to supply their people. The land they live on is very fertile and water is readily available. It should also be noted that over the years, the population has divided into four separate tribes. I'm not sure if this would have any affect.
Thanks for your time!
EDIT: Someone thought this might be related to farming and feeding a population, but this is not my concern. This place has more than enough food (farming, animals, fish, etc.) to feed their people. I'm more concerned with growth. I've added a comment below to address some of the follow up comments.
It should also be noted that I was assuming a "natural" population growth when I said they'd have enough food. They can't support a massive boom or overpopulation.
EDIT 2: People have pointed that there needs to be a limit to available food. So, guessing they would cultivate somewhere around 20% of available land, how would this affect population growth?
