If light is the fastest thing in the universe, how did the dark get there first? (as in the bible, before light was dark, "let there be light" as god said.)

Darkness is the absence of light that comes from the Sun or the moon and stars at night. Darkness is only not present when light fills the area. It honestly has nothing to do with God but more of the planetary system around the Earth and the lighting of an area. Darkness moves as fast as light and in some cases faster. Such as the theory of darkness always being present from shadows cast from objects. If you think about it hard enough you may realize that our entire universe was dark at a point until some form of light was created, only then was it ever light. So maybe even darkness is the fastest thing and the longest thing to exist. Hope it helps
