Our lives are mere phenomena , like a leaf falling or a supernova. The human ego created rhetoric, religion, and meaning so humanity could feel important.
I don't think life is meaningless; beyond being a means for the universe to wear itself out through each synthesis, I personally believe that, as a race, we take the game too seriously.
I think much of depression comes from this: from people who believed too deeply in the words of others , be it parents, religion, or idealism.
When you realize what life truly is, nihilism arrives because there's still a part of us that wants to believe in life's ideal. But after that, what comes is existential boredom.
I myself live only out of curiosity. But this "game" has a very strong anchor: pain.Perhaps in this illusory existence, the most real thing is pain.
For me, I'll live as long as the pain or the boredom isn't too strong. Otherwise, I'll simply log out of the game of life and enter the eternal night.
