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?
