I actually watched your original topic and there were some interesting question but you need to compartmentalize them into several topics. You could do that later after this topic is finished. To get this one started, you could ask creationists how their theory explains how we see stars older than 6000 years old and start from there to get a coherent theory about light, it's propriety and origins. The question is just there to show what a theory is supposed to explain.
Then, for the equivalent to Evolution in a creation theory (in an other topic), you would ask what kinds God started with (beings at the level of species? family? genus? ,etc...) and how did it go from there, giving a rough "history of life" from a creationist perspective. In a different topic, you would ask about geology, etc....
Those are just my proposition though, tell me if it's what you had in mind when you first proposed your topic.
