"Then God said, “Let us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth.” So God created man in His own image; in the image of God He created him; male and female He created them."
- Genesis 1:26-28

Dominion begins with knowledge.

The original dominion was given to Adam in the Garden when he was asked to be fruitful and to multiply and to replenish the earth, and to subdue it and have dominion over it. Man however lost his dominion in Adam’s treasonable felony, when he fell to Satan’s trickery. Adam knew God’s instructions not to eat of the tree of the knowledge of good and evil, which would result in sure death (Genesis 2:17). However, when the woman ate the fruit and gave it to him to eat, he did eat. Immediate change ensued.
