While it was dictated to them by G-d, it needed to be put into terms that humans would understand.

What was written down by those falliable humans as "days" could have been an inordinately long amount of time. A human 4000 years ago or whenever the Torah was actually written had no way of knowing a concept like millions or trillions of years. They couldn't have understood things like dinosaurs, or continental drift, or any of that. Even though our understanding of the Big Bang is still rudimentary, what's to say "Let there be light" doesn't mean exactly the same thing but in terms that biblical-era humans would understand?
