I have come across some observations which depict an interesting correlation between God and light....
In Hinduism, the Vedas and Hindu scriptures consider the Shivalinga as representing a cosmic pillar of light. The Dharmic monotheistic sect the
Prajapita Brahmakumaris consider God to be
a point of light.
In Islam, Allah has 100 name's, and one of them is Alnoor ( the Light).
“God is light,” says 1 John 1:5, in the Bible in Christianity.
In Judaism, Psalm 76:4 says of God, “You are radiant with light.”
So this correlation between God and light, is a common denominator in these four major world religions.
Imo, the fire worship in Zoroastrianism may be illustrating this correlation between God (Ahura Mazda ) and light as well, light being emitted by the fire.
If you find any further proofs or evidences in this regard, please do share it here.
Thanking you all in advance.
