That was a dialogue between the two, not a prayer. In fact the first words that the Lord spoke to Adam was an order; "“You may eat the fruit of any tree in the garden, except the tree that gives knowledge of what is good and what is bad. You must not eat the fruit of that tree; if you do, you will die the same day.”

And you see that as a prayer, do you?

God spoke to his co-creators and they answered by obeying him in the creation of mankind.
