The Unmoved Mover argument, or the "Argument from Motion", is the first of Aquinas's Five Ways and is also one of the core points in the Cosmological Argument for existence. It draws from the logic that all events we see transpiring have been caused by a line of previous events that have led up to its happening.
No chain can go on forever, so it is equally as logical to assume that the chain of events had a mover that began it all. If we deny the possibility of a state of Infinite Regress (In which chains can go on into eternity, with no beginning or end), one can argue that existence began through a chain of events that had an initial mover - the one who "lit the fuse to the Big Bang" as it were.
Some Convenient MetaphorsEdit
The Domino MetaphorEditPicture a set of dominos, lined up for miles and miles. In accordance to the laws of physics, everyonecan probably agree that every domino that falls causes the next domino in file to fall too resulting in a chain of events. Now then, while this chain of events begins with motion there is still a question - what motion begins this chain reaction?
The answer in this case is of course whatever pushed the first domino, but applying this to the First Way we can place the universe in the position of the dominos and the first push that began the chain as God. God pushed the dominos under his own volition - he was an unmoved mover because he didn't react to something.
