As early as tens of thousands of years ago, there were records related to UFOs, but the level of technology at that time was very limited, so ancient humans could only record them on rocks.
Until recent years, such incidents have occurred frequently, which has attracted the attention and curiosity of countless scientific researchers. NASA has also set up a research and investigation team to conduct in-depth research and discussions on various UFO incidents. The truth behind them No exact instructions have been given yet. Perhaps in the eyes of most people, the mysterious UFO incident is actually a natural phenomenon produced under certain factors.
Does extraterrestrial life exist?
Regarding the question of whether extraterrestrial life exists, I believe that most people have a relatively unified view and are willing to believe in this possibility. Human beings' current understanding of the universe can only be said to be half-understood, and the living environment there is very complicated, which can provide a sufficient space for survival and development for various forms of life.
Even if there is life, the requirements for the living environment are very strict, but in the macro background of the universe, no matter how low the probability is, the existence of alien life is an inevitable event.
Unable to define at this time
Strictly speaking, UFO incidents often only appear in some street stall literature. Behind these stories, there are more false and exaggerated propaganda techniques.
Researchers have concluded that most of the various UFO incidents involve special weather conditions. Of course, there are also some UFO incidents that have not received any specific explanation. It is believed that with the continuous development and progress of society, human beings can successfully unlock the secrets of UFOs in the future.
