Does Brownian Motion Really Depend on Random Motion of Particles?

In this paper the concept random is investigated, for the notable reason that it is based on probability rather than determinism. Is the question relevant Can there be an alternative explanation Are experiments biased by the theory The random movement of particles in fluids is called Brownian motion. When particles in a fluid collider with fast-moving molecules the result is a random motion of these particles. The motion is not deterministic, i.e. the particles have what is called a random walk. At the fundamental level there are flows of packages, e.g. rivers or winds that carry the smaller particles from one place to another, i.e. aRb. The validity of the random theories cannot be proven in any experiments, since the circumstances are manipulated according to the theory. Within aRb it is Nature that decides, i.e. at the fundamental level, while at the surface level chaotic motion is admitted. Imagine sliding down a helter-skelter, wobbling from side to side, but still on your way down. The conclusion: 1. The Brownian motion, i.e. why particles move, depends on the flow of packages in nature. 2. The question concerning Brownian motion is not relevant. 3. The Kinetic Theory has to be discussed.
