Genesis 5:1 (KJV)

1 This is the book of the generations of Adam. In the day that God created man, in the likeness of God made he him;

2  Male and female created he them; and blessed them, and called their name Adam, in the day when they were created.

Note, how there are two ‘in the day statements’. Is God drawing our attention to more than one important act. If syntax is synchronised with other towledah statement then this would indicate more humans created.
