HI Black Calvinist.
I have found it helpful that the sun and moon are not required for a 24 hour period for days 1-3, rather, what is required is a) light, created on day one, and b) a revolving earth, already existent, though "formless and void" but becoming less so for days 2 and 3 through the action of creation.

Have you ever check out Reformed Blacks of America? Good stuff.
