This seems a pretty deliberate over-simplification of the Biblical account that misses a lot of specific details that don't fit. Here's a more complete sequence:
Pre-creation:
1 - creates the heaven and earth
2 - the earth is "without form" and was dark
Day one:
3 - light is created
4 - light is divided from darkness, creating day and night
Day two:
5 - God creates the firmament
6 - separates the waters above and below and named the firmament heaven
Day three:
7 - gathered the waters below the firmament to create land
8 - called the land earth and the waters the sea
9 - created grass, herb-yielding seeds and fruit-bearing trees on the earth
Day four:
10 - creates seasons and the greater light to rule the day and the lesser light to rule the night, including stars
Day five:
11 - created great sea monsters, creatures that creep on land and every winged fowl
Day six:
12 - created living creatures on the land such as cattle, "creeping things" and beasts
13 - creates man and woman
Day seven:
14 - rests
Until 10-15 years ago the idea of a dark, oceanic earth was nonsense. Then came the zirconian crystal studies
from Australia - earth was wet almost from the time it formed. And dark too, according to NASA's estimation -
the earth was a cloud planet like Venus. There existed no land, or at least, continents. Water is required, oddly,
to create granite continents.
So at what point does the author of Genesis begin his narrative? We simply have no idea how many steps were
involved to bring about the earth. Do we go back to the primordial debris ring surrounding the sun? What about
the earlier formation of "metallic" elements? What about the early universe's plasma state? Or how about the
supposed hyper-dimensional membrane which triggered the Big Bang. Maybe further back, before there was
an time or space, to the formation of these membranes?
No - the bible is a theological book, speaking to Bronze Age people. It took them back as far as they could
understand (remember, there was no notion of a round earth, a planet was a wandering star etc..) and as far
back as you could reasonable expect to be an observer - that of the cold, dark and oceanic world. You have to
begin somewhere.
