Thing is, that bottleneck was way, way, WAY older than 6,000 years, so unless they found another bottleneck within that horizon..... you are making the other side's point.
Time lines are a guess by scientists who were not there to observe.
No, they are not a guess. They are a scientific estimate, arrived at through several different techniques all the while trying to disprove the theory.
Until your creationists try to disprove their own theories, they aren't "real" scientists, they are real believers.
