On what day did God create humans?

Answer: Sixth

God created mankind in His image, male and female, and it was "evening and morning—the sixth day."

“So God created man in His own image; in the image of God He created him; male and female He created them. And God looked upon all that He had made, and indeed, it was very good. And there was evening, and there was morning—the sixth day.”— Genesis 1:27, 1:31 (BSB)
