Bernoulli's theorem

But Bernoulli's theorem doesn't explain why that higher velocity on top of the wing lowers pressure.

Bernoulli’s theorem attempts to explain lift as a consequence of the curved upper surface of an airfoil, the technical name for an airplane wing.

Bernoulli’s theorem says that the increased speed atop the wing is associated with a region of lower pressure there, which is lift.

Nevertheless, there are several reasons that Bernoulli’s theorem does not by itself constitute a complete explanation of lift.

The second shortcoming of Bernoulli’s theorem is that it does not say how or why the higher velocity atop the wing brings lower pressure, rather than higher pressure, along with it.
