This is onanism - creating something and knowing exactly how it's going to behave. Like that orthodoxal @Jesus-san. So God thought
"Why not create a son and sacrifice him for human sins? Of course I know what's going to happen. No fun at all. Gonna do this anyway."
"Oh. I be creating a human. I be telling him doin' sins is no cool. He be doin' sins, I be punishin' him, I be making his life hard. Trololol".
I can kind of understand it, though... If I imagine that it's the eternal mind of the Creator which does all this by the thought and as if it's just the unstoppable flow of his mind. Like the writer writes a story.
I can't remember anything about Dinosaurs in the Bible. Maybe I just don't know the story that well.
