Genesis 1:1-5 Modern English Version (MEV)
1 In the beginning God created the heavens and the earth. 2 The earth was formless and void,[a] darkness was over the surface of the deep, and the Spirit of God was moving[b] over the surface of the water.
3 God said, “Let there be light,” and there was light. 4 God saw that the light was good, and God separated the light from the darkness. 5 God called the light Day, and the darkness He called Night. So the evening and the morning were the first day.
But I'd rather think of it as Creator Day.
