Theories on Creation?

Hey Logos folk, I'm starting a study through Genesis 1-11 in a couple weeks with a small group. We want to go through the first chapters and look at the theories of creation and examine them by scripture. I want to make sure I'm not missing any creation theories as we begin the study. Here are the ones I've heard of:

1. Literal 6 days of creation; Earth is very young. The modern science that says otherwise is wrong for various reasons.
2. Literal 6 days of creation but earth is very old because there is a gap between Gen. 1:1 & 1:2.
3. 6 long periods of creation and earth is very old (day=period).
4. 3 long periods of creation and earth is very old (day 1 = day 4, day 2 = day 5, etc.).
5. Literary theory (The first chapters are poetic and don't explain clearly the physical nature of creation.).
6. The first chapters are all spiritual in nature and don't refer to the scientific origin of the earth and humanity.
7. The first chapters are not true and the Bible is errant. Evolution presents a better theory for the origin of earth.

I know there are likely other major theories and even other ones that are nuanced versions of the ones I listed. If you know of any please post them here. I want to do this upcoming study with all the options in mind.  Thanks everybody! This will be a huge help!
