The human species has gone through various bottlenecks, but not down to 8 individuals, and not within the last 4000 years. Such a bottleneck would be glaringly unmistakable due to the immense reduction in genetic diversity that would be required. Our species has a much greater range of genetic diversity than the Flood would allow for. An important piece of evidence is the Y chromosome—only one Y chromosome would have survived the Flood, Noah’s. With the variation in Y chromsomes in the human population today, that is simply impossible.
Those who bet on God and His Word are not disappointed.
We shall see when ALL the data is in.
LOL.
