If God had to create Light does the Darkness need no creator, IOW is Darkness eternal and Light is just temporary?

Darkness is the absence of Light. If something isn't viable to the human eye we consider it to be absent but that does not mean there is nothing there. If there are other means for detection, use them. But Dark (in a literal sense) would, by my definition, be absence of anything that can be considered part of our physical universe. We can't detect something that is not part of our physical universe since all of our methods of detection are themselves physical.

Everything was created. God is what IS (the Creative Force) and everything else is Creation.

That light will extinguish some day

God chose to define His way as light and Satan's way as darkness. Light is over darkness, yet does not get rid of darkness, only regulates it.

You are wrong. God did create Darkness. He also did create time. So before the creation of time there was no time.

[All] praise is [due] to Allah, who created the heavens and the earth and made the darkness and the light. Then those who disbelieve equate [others] with their Lord.

verse 6:1 of the holy Quran

Is this a physics question?

Darkness is immaterial and immaterial things don't come into existence at some point in time/ they can never be created. There are many other things that are immaterial and exist forever e.g temperature/pressure/time/space/love e.t.c

Darkness is privative. Just like you say " I have nothing to wear" -- well, you can't wear 'nothing' , it is not the same as "I have pants to wear"

No be quiet

Darkness is a void

It is defined by light

Darkness is light - it just happens to be light outwith the visible spectrum.
