For example, the second line is nine. That's 3+3+3, the three surviving children of each of the three initial couples. The parents are not included in that number. We're accounting for death.
Three children per couple seems reasonable, but let's lower it. Set the growth to just 10%. Now you hit 7 billion in the 293rd generation. If a generation is 20 years, that's 5,860 years, and we're not even building in the effect of the early long life spans.
It just doesn't take that long.
How can you neglect the fact that these people would have been inbreeding with close, biological relatives for multiple generations? It didn't work for the European aristocracies, many developed genetic diseases such as hemophilia, it certainly would have been less successful 6,000 years ago when Christians believe all of this was going on.
