How did God create the world ?

Yesterday night when I was brushing my teeth this funny idea came to my mind. As you all may know, God created the world and it took some time too. Then he created Human, first a man, then taking a rib born, God created a woman. Anyway, let it be like that. Here is what I was thinking yesterday. Why did the God create some dinosaur skeletons? Isnt that funny? Do you think it is a part of God's plan ? or ?
