 When you make an age estimate, you are basically using a calculated number based on assumptions about the past. And as I've noted before, creation scientists and secular scientists have different starting assumptions. We have different assumptions about the rates and the initial conditions. And so we come up with different answers. So how do you tell who's right? You know, I can make one set of assumptions and get one set of numbers. You can make another set of assumptions and get another set of numbers.
