If nothing is faster than light then how did the dark get there first?

Get WHERE exactly? It isn't clear at all what experimental setup you are thinking about. Please note that:* Darkness is not a thing in itself; it is merely the absence of light. Darkness doesn't move around.

* There are lots of situations in which there is an apparent movement that is faster than the speed of light; the point is that in none of these cases matter, energy, or information actually gets faster than light, from one place to another.
