What constitutes proof of a futile existence within the framework of cosmic determinism?

*If we consider the idea that our existence is predetermined by cosmic forces*, *what evidence or reasoning could we use to justify the notion that our existence is futile or meaningless? Are there any philosophical frameworks or theories that already explore and substantiate this idea*, or *any insights from science or history that could support or refute it? For example*, *according to determinism*, *our thoughts**, *actions**, and *beliefs*, *including our goals and aspirations**, *are ultimately the result of causes outside of our control*.<br><br>**From a determinist perspective*, *is our existence truly futile in the face of cosmic determinism? Is our existence within a deterministic universe futile in terms of our individual goals*, *beliefs*, and *actions? Or are we simply passive observers in the grand scheme of the cosmos**,* *helpless to shape our own destinies*?<br><br>*We could argue that even if the course of human history were predetermined*, *the futile nature of human existence would still be a valid perspective*.<br><br>*There's a great deal of existentialist and nihilistic philosophy that explores the idea of life's futility*, from *Arthur Schopenhauer to Martin Heidegger*, but I'm talking about futile existence within the framework of cosmic determinism and not just existentialism or nihilism.
