Well all that is definitely included in the creation process of the earth to what it is today. Its why I would consider the point in time when the 2 grains of sand got stuck together as the start of the earth. We are talking about the beginning of earth's creation process after all. And this process began exactly at the moment of the gravitational collapse of the interstellar molecular cloud, no? Wouldn't thinking that the earth is 4.6B years old be correct if you frame it like that?

Question. We know the earth is 4.543B years old, but what exactly does this number mean? Technically, wouldn't the creation process of the earth have started right at the moment of the solar system's beginning? (i.e the exact second of the gravitational collapse of the giant interstellar molecular cloud, so 4.6B years ago, adding about 400M years to the age)
