The time scale of the bottleneck?

@aarceng,

But you have a problem; actually, a couple of them:

  1. You have to jettison a huge amount of naturally evident demonstrations not only of the antiquity of the Earth, but that whole groups of animals have genetic legacies that can only be interpreted as common descent.

  2. You don’t have a very good explanation for who mated with the offspring of Adam & Eve - - intertwined with who thought Cain was in danger from, for whom he built a city, and how did humans get all their genetic diversity if there was a single mated pair any time within the last 500,000 years!

  3. All you need is Adam/Eve, just 2 humans, specially created by God.
