Interestingly, if we were on a planet that didn’t rotate these pressure differences would equalise quite quickly. However, because the earth rotates, the air moving over the surface is deflected(to the right in the northern hemisphere and to the left in the southern hemisphere). This is due to the coriolis force created by the earths rotation(which also affects tides). This deflection makes the presure differences “longer lived” and we get the familiar depressions(low pressure) and anticyclones (high pressure) structures.

Yes... That is the explanation of wind on the whole!... but for it to be proven in Science, they would have to be able to predict it. i.e. with enough calculations, you could tell that a gust of wind will hit your face in the next 5 seconds. Or, if you're given enough variables, you could tell what would happen. But the truth of the matter is, wind is too erratic, and therefore, according to the "methods of Science", Wind cannot be proven or be said to be a law or whatever!
As stupid as it sounds, that's how it is. I don't feel that there is a need for any more information to prove that wind exists, but my point is that Science is very pedantic!
