The Unmoved Mover is a concept based out of Aristotle, a far more complicated thing than you can even fathom to understand. It's based on the fact that in Physics, every action has a reaction, and thereforth. Basically cause and effect, where everything is predated by something else.
Example:
I throw a rock in the pond.
The pond creates ripples.
One Ripple kills a bug.
That bug was about to lay eggs.
Those eggs were never laid.
Those new bugs were never hatched.
Therefore they never got the chance to exist.
That is sort of what the Unmoved Mover is, but in a more complicated fashion. More like.
Example:
I was born from my parent.
My parents were born from them.
Going back far enough we came out of something else.
The sun was formed out of previous stars, in cosmic clouds.
The universe was born in the big bang.
What created the big bang?
The final one in that string would represent the Unmoved Mover. It is conceptually something which exists solely on it's own power. It does not exist because another created it, it has always existed.
"... if it had to perish twice,
I think I know enough of hate
To say that for Destruction Ice is also great
And would suffice."
- Robert Frost
