The real fact is that regardless of disease, natural disasters, wars and famine, human population has never stopped growing. History proves that Humans are able to impede animal growth but never their own.
Ok, if I can't talk about your alternative theory on this (that the human population started out with 10 people 6 thousand years ago), let's talk about why steady human population growth only started happening in the last 10 thousand years or so. The reason is so simple that I'm surprised no one has mentioned it yet.
Farming! Hunting and gathering ain't enough to support a large population in any one place. It was only recently, around 10,000 years or so, that early civilizations began to farm on a scale capable of supporting more than a few dozen people in any area. And even then, it took thousands of years for farming techniques to develop to a level that could support major population growths.
