For all we know the period after the end of creation and before the fall of man, when Adam and Eve ate the fruit of the tree of knowledge, was a day. It could have been years. We aren’t told. We are told that the creation fell and began to decay.
Before this happened, however, the earth was a complex planet with a hydrological cycle which involved water of the great deep cycling through the interior of the earth.
