False Prophecies of Mormonism Creation Confusion

Abraham 1:23; “And God saw these souls that they were good, and he stood in the midst of them, and he said: These I will make my rulers; for he stood among those that were spirits, and he saw that they were good; and he said unto me: Abraham, thou art one of them; thou wast chosen before thou wast born.”

Genesis 1:26; “And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.”

For the sake of the argument let’s say God was an exalted man up there in heaven before the world was. 

When he got ready to create Adam, why didn’t he say “let us make man in my image” instead of “let us make man in our image”?
