By the way, you've been on this site long enough to have seen me around, and I would hope you'd recognize that I'm one of the staunchest defenders of Creationism. I'm not your enemy, although in your zealotry you might perceive me that way.
Three things:
1. You're probably right, I probably should know you by now. But I really don't. Sorry.
2. No, you're mistaken: it doesn't contradict logic in any way. Or if it does, you've not demonstrated it.
3. No, you're mistaken again: it doesn't contradict creationism. The pattern of the six days of creation (which I take to be six historical, common-sense-of-the-word days, relatively recent) is form and fullness. Day one, light; day four, light-bearers; day two, sky and water; day five, birds and marine life; day three, dry land; day six, animals and man to live on the dry land.
So God was preparing the world for man, the crowning act of creation.
