I know you are joking, but in a way it is a win for creationists. After 2.8 million years, we have under 8 billion people on earth. Statistical models just don't support it. You have creationists that believe there could have been more people on earth prior to the flood than there are now, in just 1656 years when the lifespan was ~900 years per person. My great great grandparents had 11 children that lived to adulthood, and my grandparents had 6...try running those numbers. At just 4 surviving children per parents, using 33 years per "generation", you easily hit 8 billion in 1000 years.
