I see so 1 John 1:5 is a lie?
Do you not know that there are many kinds of light? God is light. He also created light. God is not His creation. I have lights in every room of my home. It's not God shining out of them. God created the sun and the sun gives light. God is not the sun. No, 1 John 1:5 is not a lie. Your issue is a lack of logic and reason.
Genesis 1 has this to say:
And God said, “Let there be light,” and there was light. And God saw that the light was good, and He separated the light from the darkness. God called the light “day,” and the darkness He called “night.”
And God said, “Let there be lights in the expanse of the sky to distinguish between the day and the night, and let them be signs to mark the seasons and days and years. And let them serve as lights in the expanse of the sky to shine upon the earth.” And it was so.
God made two great lights: the greater light to rule the day and the lesser light to rule the night. And He made the stars as well.
God set these lights in the expanse of the sky to shine upon the earth, to preside over the day and the night, and to separate the light from the darkness. And God saw that it was good.
And there was evening, and there was morning—the fourth day.
Your reasoning says that God said, "Let there be God". God did not make Himself.
