Certainly it's how it happened. I'm just looking at the First Day in terms of density, when everything in the universe was condensed in say, from the volume of a basketball to perhaps a Betelgeuse type star or larger. As the universe expands and the density decreases, galaxy formation takes place, and thus the stellar cycles which eventually give rise to our Sun, and the planets.
Somehow (God!) life began on Earth when it was still very young, continually baffling scientists, though nonetheless, eventually giving rise to all of us. (The evoluted parts are yet very sketchy.) Though I remain convinced that's pretty much the basic outline.
"In the Beginning, God...."
