Why did God appear to the Israelites in Moses’ time as a very bright light in the sky? The Sumerians (of whom Enoch was a prominent leader around 3000 BC) had a word for God which is written as a star (asterisk) symbol, pronounced either as AN or as DINGIR. https://en.wikipedia.org/wiki/Dingir This last way of saying “God” - Dingir - has persisted throughout subsequent history even up until modern times in the form Tingir in the oriental parts of the world. The translation of these people of this word for God into English is Eternal Sky and associated with they phrase regarding God, The Eternal Blue Sky. The Sumerian symbol of the star asterisk Dingir was very much associated with the sky, the high heavens. So the appearance of God as a bright light in the daytime sky must have evoked the most widely understood concept of the supreme, most high God, in the ancient world.
Thousands of years later another great light in the sky was seen when the hater of Christians Saul of Tarsus was struck with blindness on the road to Damascus from Jerusalem by the light of the Messiah. The appearance of Jesus to Saul (who became Apostle Paul) associated this Messiah, this Christ Jesus, with the sky too and so the awareness started of the sky being associated with both Almighty God the Father and Lord Jesus Christ the Son and this would continue and spread worldwide even to this present day.
