Description
Life was bound to come, though it took a long time. Our world began about 5 billion years ago. The sun is about that old, and the earth only a little younger. The oldest rocks on the earth are less than 3 billion years old; it seems to have taken almost 2 billion years for the crust of the earth to settle down enough to hold rocks in place.
