Answer:
Inertia
Explanation:
During the birth of our Solar System, due to inertia and multiple other forces, the Earth was "born" spinning and has spun ever since its creation. The cause for the inertia could have been due to an object hitting the Earth during early creation or perhaps tidal forces from other large, celestial bodies.
