Perhaps the pebbles tumbling about in a stream think that they are responsible for the current's flow. We are just bits of matter tossed around in the currents of time and space. What will be, will be and there is nothing we can do to change it. Even if we could, it wouldn't matter in the end. This isn't a pretty picture.
Most people find it depressing.
Even I do when I think about it, but at least I'm not deceiving myself.
