Ilgaitis,
Re "There is only motion" [1]; "The initial cause of motion is force" [2]:
Yes, a force is a result of a quantum mechanical particle interaction, involving quantum jumps, that changes the motion of particles. But the motion of things is closely related to the question of time: how would we detect time if we never observed motion?
The laws of physics don't change, so how does physics represent motion, given a frame of reference? Motion can be thought of as a change in the numbers that apply to some of the variables (e.g. position, velocity, acceleration, energy, momentum) in the equations that comprise the laws of physics [3]. These laws don't ever initiate number change: the laws of physics merely represent number change relationships using the delta symbol. But seemingly all number changes in the universe are initiated by quantum mechanics e.g. the quantum jumps in particle interactions.
So, our sense of time comes from the number changes initiated by (what we call) quantum mechanics.

3. The laws of physics are assumed to represent laws of nature.
