I'm sorry, I never was one for philosophy. How does that follow?

The reasoning is essentially that if it's possible, then it's been done. If it's been done, then the odds that we are in the original universe become extremely low and the chance we are in one of the turtles-all-the-way-down simulations conversely high.
