What do you mean the "other's" spin. The moon is rotating, but isn't
spinning.

The Moon.
No.
The simple answer is, to remember that without friction, an object will
spin
forever unless there is something to influence it. The junk that came
together to form the Solar system was all moving, and the spins this
imparted onto the objects as they formed, has been retained, _except_
where
something else influenced them. The collision that led to the formation of
the Moon, will have changed the spin on the objects concerned, but the
objects were spinning before this. Afterwards, the gravitational pull
between the Earth and the Moon, have both influenced the other's spin, but
didn't 'cause' it.
In a sense, not spinning, would be the unusual case.
