I received the Cepher in the mail and decided to start at the beginning. I couldn’t get past the first 18 verses without rereading them several times. I am perplexed and the “light” referred to in verses 1-5 (1st day) in comparison to the lights placed in the expanse of the heavens (4th day). In the past I had always assumed that the light created on the first day was the same as the sun and moon. It appears they are not. Can anyone expand on this?
