You're making the assumption that the ground is a planar surface, something that does not occur in reality. The individual silica molecules are three dimensional, non planar and vastly larger than a photon. Its the angle at which the photon strikes these molecules that matters, not the angle at which it strikes the overall surface. So the angle is not necessarily whatever you measure it to be because the surface is actually more fractal in nature than it is planar, thus of course it does not reflect at that angle. There is nothing there to contradict the current theory of light. However i do commend you for at least looking for an experimental reason to discard the theory.
