To understand the four-dimensional world, we first look at it from another angle. Why are there all kinds of gods, Buddhas, demons, and ghosts in ancient times? Is this really just caused by feudal superstition? So why both the East and the West were invariably filled with these cultures in ancient times? Let us boldly assume that all legends are true. So where are these gods and demons now? They almost follow the human evolutionary history . It just disappeared suddenly at a certain time. This time is almost the same as the time when humans entered modern civilization. So can we think that people created them? In other words, human beings are them-ghosts.
They disappeared after mankind entered modern civilization. This time is also the time for human beings to realize that they admire freedom and individual rights. It is the time for the gradual improvement of various social systems. And because of the imperfect world system in ancient times, many ancestors’ heroic spirits can enter our world and guide and teach us? . So can we think that the heroic spirits of our ancestors made the rule that all ancestors are no longer allowed to enter our world?
If this assumption is true, then we live in a three-dimensional world, can we assume that they live in a four-dimensional world? In other words, the end of our life in the three-dimensional world is the starting point of our four-dimensional world.
then can explain why human beings have not yet discovered the existence of aliens. Perhaps the earth has been visited by aliens countless times, and our ancestors in the four-dimensional world received them, but we in the three-dimensional world have no way of knowing the contrast.
