A timeline is created sequentially, so if something doesn't work out with the timeline that has already been created, you go back in time and redo it. At that time, the timeline that was once created remains like a shadow or afterimage, and it appears to be in the future from the current timeline.
In reality, the true meaning of the future is both there and not there. It exists, but the future can be freely changed based on the current will.
A template-like form comes down from higher dimensions, and a vague prototype of the timeline is created, but there is still room for individual free will, so it doesn't always follow the prototype.
After the timeline is formed, if higher dimensions say, "That's not quite right," a new prototype is sent down from higher dimensions, either from the future of the current timeline or slightly from the past, and sometimes the future continues as is, and sometimes the timeline is redone after going back a little.
In such cases, very few people can actually see the prototype from higher dimensions. It is not a timeline, but rather a "will," and because it is a will, the actual timeline does not exist until it is "seen." The "will" of higher dimensions comes first, and when that will thinks, "How about this?" and "sees" the actual form, a timeline is created for the first time, reality is created, and only then can it be predicted.
Surprisingly, reality seems to be created all at once, across all time. Human consciousness can only perceive each part of the timeline, and even if you astral project and transcend time, you can only see specific moments of the timeline at a time. Even if you can astral project and transcend time, there are limits to what you can perceive.
On the other hand, what we can call "God" is actually a highly concentrated aura, which is a very large and pure consciousness, and it is essentially the same as humans, but the amount of aura and its purity are on a completely different scale. When such a being, which we can call "God," decides, "Let's do this," reality is created, and the timeline is instantly materialized. However, even so, creation seems to have a time axis, and within the range that the will reaches, a time axis is created within the range that "God" intends, and there is nothing beyond that, but as the perception within that limited time axis progresses and people's consciousness increases to a certain level, the "God" who received that perception is satisfied, and then moves on to the next era.
Therefore, time periods often involve repeated attempts, and if the lessons of that era are not completed, the timeline reverts and restarts.
Recently, tragedies involving nuclear explosions destroying the Earth have frequently occurred in timelines, and countless timelines have been restarted. Whether this timeline will succeed depends on humanity, but at least, most of the people who claim to predict the future are actually seeing a timeline that has already failed and is about to be restarted.
There are certainly people who are seeing the future of the current timeline, but that is a spoiler, so there is not much meaning in seeing the true future, and even if they could see it, it would be boring, so they choose not to see it, or they are simply not interested in seeing the future. However, seeing examples of failures as future predictions can have some meaning as a lesson.
Sometimes, special programs like "behind the scenes" of television shows feature how they are portrayed, but they don't reveal spoilers, do they? Ultimately, seeing the future is only of limited novelty.
