If it had a beginning, it shall have an end, also. Even the solar system may not survive eternally. It would not be a wise complacence on the part of anyone to imagine that everything is fine, as it appears on the surface to the sense organs. Things come, and things go. People are born, and people die.
Empires rise, and empires fall.
Caesars and Napoleons have come, and many have gone, also, at the same time. In this mysterious presentation of the history of the universe, the history of humanity, nothing seems to be enduring, and even when something appears to be enduring for sometime, we do not know for how long it will endure. None of us knows how many minutes more we will be in this world, let alone years. There may be only a few minutes, for some reason. We have to learn by past experience, and by history.
