26 Then God said, “Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth,[b] and over all the creatures that move along the ground.”

27 So God created man in his own image,
in the image of God he created him;
male and female he created them.

28 God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground.”
29 Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. 30 And to all the beasts of the earth and all the birds of the air and all the creatures that move on the ground—everything that has the breath of life in it—I give every green plant for food.”

If the above is correct, any of the races in my fantasy that are actually sentient, are, in a sense, images of beings that are Imago Dei. I think.

That's a great thought, Seer. I also think that part of us being made in the image of God causes us to make things. He is the Creator, and us being in His image then makes us creators too, though not to His grand of a scale.
