To establish causality, the independent variable must come before the dependent variable. This temporal precedence is necessary to show that a change in the independent variable caused a change in the dependent variable, rather than the other way around or some other factor entirely. Correlation (positive or negative) between two variables does not necessarily mean that one variable causes the other, and spurious relationships can falsely suggest causality.
