And that evidence is the state of the cosmos today?

Are you a software developer? Imagine that, for testing purposes, you want to test a particular state T in a simulation app that you believe can only occur organically after a large period of time.

Do you start the test simulation at a hypothetical t0 and wait to reach the desired state? Or do you simply bootstrap the simulation so that it starts in state T.

Well, you do the latter of course. So do the events at t0 need to occur for you to observe state T?
