Creation, De-creation, and Re-creation

<p>Did planet earth exist before creation week? How could there be light and darkness and evening and morning the first three days if the sun was not created until the fourth? Will the Sabbath exist on earth during the millennium? Are the signs in the sun, moon and stars of Revelation 6:12, 13 the same as those in Matthew 24:29? In how many days will God re-create planet earth? What will the final inheritance of the redeemed be like?</p>
