I am exactly right on the same thoughts as you on this.
One can actually “predict” the future based on their knowledge and experience
of knowing what “happens” to “A” when you tinker with “B”.
Do weather forcasters “predict the future”?
Having said that, I do generally subscribe to a 'multiverse' view of reality, and do reckon that there are occasional folds and wrinkles in time-space, whic may account for some claims, but I think for the most part, we're aware of far more than we give ourselves credit for.
