Imagine a time when there was no human thought, just rocks forming the solar system.
Every rock follows the laws of physics, if bumps in to another rock you should be able to calculate, if you had a powerful enough computer where that rock and the one it bumped in to would end up going and the velocity it would be traveling at.
When I throw a ball to someone as it leaves my hands. the person catching it can predict where it will land, and place their hands in that location and catch it. They can only do this because the trajectory of the ball is predetermined by the laws of physics, which are the laws of the universe. if the laws of the universe did not exist the ball could suddenly change direction, but we know this never happens and no one has ever seen it happen.
The ball is made of atoms which all matter is made of so, once you make matter move it will continue to move until forced such as gravity or your hands which catch it change it motion.
We are made of matter, our brains are also made of matter and all this matter follows the laws of physics, if I was to zoom in on my hand and see the atoms bouncing around, bumping in to each other , they all must follow the laws of physics, I have no control over this process. so it I move my hand the atoms need to bump together and energy needs to be released for this process to happen, a process which I have no control over in the quantum world, but in the macro world I think I do
