Genesis 1 is active. And you skipped over a whole bunch of it, in order not to make sense of it. The 14-25 skipped part was the active process of God doing everything prior to the action in 26.< Let us make man.( present tense active ) As with any good Father, the "nursery" was finished before His child arrived.
