Whatever time is, our favorite way to 'pass' it is by generate entropy. Chemistry explains inorganic things, those inorganic things become increasingly complex, eventually able to reproduce somehow, so you look to biology for explanation. You get evolutionary biology which might kind of explain how we came to be (super-self aware beings, capable of perceiving things, like time for example, or creating the internet to share ideas, or cars to commute). Then social/behavioral sciences attempt to explain us specifically. But even more fundamental than that first step (chemistry) is physics and math. And physics and math tell us that we are moving to a state of more entropy. Sometimes it feels like this is the best explanation for why we behave the way we do (driving to jobs we hate to do nothing important, making nuclear bombs, etc.). End result is we're fked!
