It's either angular momentum or little white bunnies all hopping in unison.

It doesn't take any force at all. It would take force to STOP it from rotating. Once something is rotating, it keeps on rotating until some outside force stops it. For the Earth, the main outside force is tidal friction from the moon, which will take billions and billions of years to stop the Earth. Long before that happens, the Sun will expand and melt the Earth.

There is no force that makes it happen. A force is not required to maintain unaccelerated motion. Earth was rotating as a consequence of it's formation, as most celestial bodies do. Our rotation is actually slowing down due to the friction of the tides caused by the moon. However this slowing is miniscule. It won't be noticeable in our lifetimes or the lifetimes of our grandchildren's grandchildren.

The original gas cloud was spinning (see the nebulas spinning) and from that the planets were formed. Thus the momentum is continuing even now. And if the gas cloud condenses, the seed of rotation increases to conserve the angular momentum.

It's not a force that keeps it spinning, but a property of matter we call inertia. This spinning motion is left over from the formation of the planet eons ago, and there is so little friction in space and Earth so massive that it is still just spinning away.

Gravity and inertia. Gravity is that tension which binds count at the same time in accordance to their weight. Inertia is in basic terms a regulation that states that issues in stream has a tendency to stay in stream. consequently, the planets are attracted in direction of the sunlight, yet being in stream, they have a tendency to proceed on their stream. The stability between gravity and inertia produces an ellipse. This stability between a repelling and an appealing tension is likewise generally defined as centrifugal tension. (the place gravity must be understood as a string attaching the planets to the sunlight for clarification applications).

Momentum... an object in motion tends to remain in motion...
