The World's Great Sermons V1 - Grenville Kleiser - Bog

As nothing of all this yet existed, Scripture is right in calling the earth "without form." We could also say of the heavens that they were still imperfect and had not received their natural adornment, since at that time they did not shine with the glory of the sun and of the moon, and were not crowned by the choirs of the stars. These bodies were not yet created. Thus you will not diverge from the truth in saying that the heavens also were "without form." The earth was invisible for two reasons: it may be because man, the spectator, did not yet exist, or because, being submerged under the waters which overflowed the surface, it could not be seen, since the waters had not yet been gathered together into their own places, where God afterward collected them and gave them the name of sea.
