I saw that time shift error is flawed by the reason that we can not ensure that future and the present would be the same as the past.

But at the same time, we use a premise like "Histories proves.". I thought we could use the past as the evidence that future and present would be the same as the past. I thought it's like an analogy of past and present or future.

Is there some body help me close the gap between the above two?
