It isnt difficult. It is impossible. You cannot rewind ash to the material that was burned into ash. Let alone reverse the state of every particle in existence to a previous state.

Even if that were possible, how do you simultainiously revert every particle in existence backwards to a previous state while keeping your own in their current state?
The answer in short, you cant.

You keep thinking of it as a physical or manual process to have to adjust the state of each particle.

You're way overthinking it.

Think of it like taking a snapshot. The person operating the camera doesn't know or care about individual particles.

And the person viewing this photo of a past event doesn't know or care either.
