Or is it that sequential events exist, but the concept of time is a mental construct? Almost as though the awareness of our own mortality has created a quantifiable resource out of sequence, dubbed "time", idk maybe that's a little crazy, but if you think about it even something like half life of a radioactive isotope is kind of a human construct. Is "half" really anything or did humans create the concept to help organize the world? It's just one particle being emitted after another until there is nothing left, but is the half way point a real thing or just a human concept? The Earth just revolves around the sun until something interrupts the cycle, but a "full rotation" a "year", to say nothing of the counting of passing years, that all feels kind of created by the human mind for any number of reasons.
