I'm saying two things:
- Many, many people (if not most people) who know a thing or two about aviation, some of whom are pilots, have a false understanding of how lift is generated.
- Hydrodynamics, aerodynamics and thus the nature of lift are observed phenomena, for which the mechanics are empirically observed and theoretically deduced to form a single universally-accepted theory.
On the first point:

There is a widely-held misconception that it is the velocity relative to the skin of the wing that produces lift. This causes no end of confusion.
Bernoulli’s principle is very easy to understand provided the principle is correctly stated. However, we must be careful, because seemingly-small changes in the wording can lead to completely wrong conclusions.

A full discussion of turbulence and/or separated flow is beyond the scope of this book; indeed, trying to really understand and control these phenomena is a topic of current research.
And there even seems to be argument here:
