Or is a root of a word is what you will find. It is to Christen… like to give way to a fresh or first of something. This is like to christen a ship as the first time it touches water. This is semi true with space as the star in our galaxy is always moving so technically the light that breaks every morning is christening the sky for the first time… it is in. It is only the layers of our Earth that shade as such it is. This where Uranus was known as the God of the sky in this aspect so then these meanings are subjective. To baptize is a different meaning means to wash clean or start a new in a way. There is a difference in aspect of these things. Anyways
This is going to the also some of the ideas of energy and the shapes of light in things as well. As light moves one way so as this energy moves it is never the same as it goes along. This is where the son is christ like in ways and is chosen in ways of writing to be like it coming over the horizon is all ok.
