Did God create humans separately?
God created humans separately to be in his image. Adam was created first, and Eve out of Adam. This is a personl act of a personal creator.
Man is the only creation not prefaced by And God Said. God formed man specifically and personally out of the dust of the earth. And has been caring for us specifically and personally ever since.
Which version of Genesis are you looking at? Because in the first account, Humans were created after the other animals. But in the second account, Adam was created, then the animals and then Eve.
