In this context I mean price. Nothing else.

Ask an economist or investor why the market goes up or down and you'll get many reasons, some may be right, some may be wrong.

Ask a trader why the market goes up or down and you'll get supply exceeded demand, or vice versa.

You can have a fun debate about everything the first two care about, but at the end of the day, only the price action will feed your family or improve/worsen your standard of living.
