I can respond to your query in the positive!
There is the physical darkness which is good because it means there is a cycle to life in the physical. Biggest meaning in my opinion is the contrast of things, the divisions if you will.
It is in the divisions of things is where things multiply. Where one is divided, another is created, such is life.
Now, that was the physical necessity for darkness in a sort.
There is however, a larger definition of darkness and that has to do with knowledge.
If there is no knowledge of anything there is absolute darkness.
Life begins in the dark, as no baby about to be born has no knowledge what so ever except the need to feed.
So, we can say then that out of darkness knowledge is born given that there is light to shine upon it.
Now like darkness, light is knowledge available and reachable.
In the case of the story of Adam and Eve, they were both in the dark as far as knowledge was concerned because of the very fact that there is a mention of a tree of knowledge available to them in the physical, meaning that they were alive in the physical but without the spirit of discernment, meaning having the ability to make judgments between what is good and evil.
Good and evil is defined by some by many in many different ways. But for this explanation I will define evil as our ability to determine the difference between when we know we do good and the when we know we do evil.
That determination ability is termed the conscience.
Every person has a conscience to varying degrees. The degree depends on the individuals desires based on the ability to want, as gods, the things that can harm us verses the things that can help us.
A desire to steal for example is one where the individual is exercising the right as a god to choose between what is good and what is evil.
Darkness = lack of knowledge =lack of spiritual knowledge of which light of God has come into the world as a lamp unto our feet and to draw us out of the darkness into the light of God's existence. To give us individual worth and salvation after this life is over with.
The good news is, that regardless of what age of human history we are born in, whether we acquired such knowledge or not, we are all covered.
That is the beauty of the love of God.
