I think people might be missing the point of your question. I am assuming you are curious why they are all going in the same direction rather than caring if it is clockwise or counterclockwise. This is because there would have been stuff going all different directions early on but slow things crash into each other and are destroyed/broken up or pushed in a new direction until eventually you are left with only the items going in the dominant direction (and which way the dominant direction was, was just chance).
If you look at them from the south, they spin clockwise. So your question is basically asking why astronomy advanced the most in the northern hemisphere.
Since the sun and all the planets formed from a cloud of gas and dust, they mostly have the same spin as that cloud did originally. The axis of the spin points to a random direction in the sky. By convention we record the direction of the north pole axis and say that objects rotate anticlockwise. We could just as easily choose the direction of the south pole and say that objects rotate clockwise.
Another answer is that our definition of clockwise comes from (northern hemisphere) sundials. In other words the sun is defined to appear to move clockwise across the sky. For the sun to appear to move clockwise, we must be watching it from something that is rotating anticlockwise.
That was the way the disk they formed from was spinning, and conservation of angular momentum means that everything will keep going in that direction unless something makes it go in another direction.
> This is the same for satellites and solar systems.
For artificial satellites, it’s because launching in the direction of rotation is easier and cheaper, because you’re adding the rotational velocity to your craft’s velocity rather than working against it.
For natural satellites it’s conservation of angular momentum again.
