But “preparation” would seem to require actual, physical events, not just an abstract assignment of purpose. And elsewhere you refer at least obliquely to major physical events happening on particular days. You are still being very confusing. It seems from what you say here that your understanding of Genesis is incompatible with our scientific understanding of earth history. And while I don’t see a problem with that, it seems to me that you do and are trying to minimize the distinction. We can’t set a date for the week of Genesis 1 because there is no point in earth’s history during which any such radical alterations of the environment happened within a short time. And if the week didn’t involve physical changes, your language is at best confusing.
