The primary property of life's self-preservation in the history of evolution on Earth subsequently formed the sensation of pain and fear in living beings. As the human intellect's capabilities evolved, people began to realize their mortality, and since it contradicts "deep needs for self-preservation," it was perceived very painfully and gave rise to deep existential anxiety. The problem of managing the fear of death arose. Apparently, the "wise men" of that time, to solve this problem, resorted to inventing and systematizing mythology and mystical teachings, representing death as a transition to another, eternal life. Perhaps these tools helped the people of that era overcome these fears and find existential peace.
Truly, the flight of human thought is high, and the inquisitive mind wishes to know everything about the mysteries of space and time already today. And thanks to our curiosity, a great deal of substantiated knowledge has been accumulated, convincingly explaining the most important and relevant mysteries of existence. Of course, it is important to continue persistence in understanding, but to find all the remaining answers, humanity will need to become at least a galactic civilization. And to achieve this, without losing balance, we need to make worthy use of the available answers to make life more meaningful, joyful, exciting, and future-oriented.
