There is nothing new under the sun. This is a saying from the "Bible Old Testament"
It means that human beings have never learned the lessons of history. What is happening now will happen again in the future. What happened has already happened in the past, and history will bear witness to what has happened.
The same experience, the only difference is the different results. In the thousands of years of human history, the difference may only be the difference in economic level. It can be said that most of the time has its shadow in history, and even the results are surprisingly similar. But there are always the same events, just with different results for different protagonists.
There is a saying in the Bible: "There is nothing new under the sun. What has happened will happen again!" This sentence is true. Things change only in appearance, but not in essence. For example, it seems that society has progressed now, but in fact, the essential purposes of power struggles, wars, etc. are the same as they were thousands of years ago.
The essence of things is unchanged, so the nature of ancient people is no different from that of modern people. Our current experience has been experienced by people in history, which is also the value of history. It can also be understood that under the light, all monsters and monsters have no hiding place, because the sun is bright, it destroys evil and eliminates evil, and conspiracies and tricks cannot be seen in the light.
The context of this sentence is generally when people encounter something that is difficult to understand, and the experience of such things can be discovered from history.
As the saying goes, if you don't get surprised, you will lose yourself. When we encounter something incredible, there is no need to panic and wait for the test of time.
