Matter and energy cannot be created nor destroyed. Both matter creation and spontaneous motion are against by the laws of physics.

The current theory of the perpetual expansion of the universe is that all objects are moving away from the universal center due to the Big Bang. It is supported by observations of directional movement and evidence of perpetual slowing toward universal entropy. That explains the motion we observe in all of existence. It does not explain the existence of two enormous masses prior to the Big Bang, nor what caused them to be in motion to collide in the first place.
