Explain the origin of earth's motion based on the origin of the galaxy and its solar system?

There are numerous theories as to the origin of our galaxy and our solar system within our galaxy.  I have attached two references that will detail several of them.

As far as motion of the earth, our planet has a prograde revolution around the sun. Prograde motion would be a counterclockwise motion.  All the planets in our solar system have this prograde revolution.  They all accomplish this revolution in the same plane.  Most all the planets have a prograde roatation, like earth, as they perform this revolution.

One of the theories about how the universe and the galaxies and solar systems were formed after the Big Bang is a theory called the "nebular theory."  A nebula is a gas and dust cloud.  According to this theory, the gas and dust particles collided with each other, were gravitationally attracted to each other, and got progressively larger.  As this formation happened, a centripetal force was created by the force of the collisions and the mass of planets began to spin and revolve.  It should be noted there is room for the revolutions and rotations to go one way or another, depending on the angle of incidence in the collision of said gas and dust particles.  This would be one accounting for the present motion of the planetary constituents in our solar system.
