In verse 14-15, God made the lights associated with these already-present celestial bodies, from the perspective of the surface of the Earth. This indicates that the Sun and Moon faced utter destruction as well, similar to what we shall see in the last days. (The Sun turning black, the Moon turning red, etc.) It could also indicate that the first heaven (the Earth's sky) was darkened (with dust, etc.) resulting from a catastrophic event. I've long suspected that pieces of Tiamat/Rahab played a role in the judgment of Pre-Adamic Earth. The point being, in Genesis 1:14-15 God permitted these sources of light to reach the surface of the Earth.
The Stars, Sun and Moon were created in the beginning, and brought to destruction between Genesis 1:1 and 1:2, but regenerated in Genesis 1:14-15, just as the Earth itself was regenerated.
Here is an excellent article in defense of the gap theory:

Gap theory believers are rare nowadays. But then, so are Fundamentalists.

But there is NO destruction in the creation story. It is all creation, and peaceful creation at that. This is one of the many aspects (besides truth) that sets our creation story apart from the pagan creation stories. Those stories all have battles between gods, and things like the harvest results. God however, is the only game in town, and He is supreme. He just speaks, and it comes into being.
Clue #1: Compare the phrase "the heavens and earth, which are now" to the phrase the "heavens were of old":
What does that mean? Ask yourself this question: When Noah's flood happened did it change anything in the upper heavens? Would a flood on the Earth have any effect on the sun, moon, or stars? The obvious answer is NO. The heavens of Noah's days were the same heavens as in Adam's day; same sun, same moon, same stars. FACT: Noah's flood had no effect on the upper heavens. All of Noah's flood's effects were confined to the Earth's surface and atmosphere. And although the Bible speaks about the "windows of heaven" being opened and water coming down (Genesis 7:11), the context of that reference is the "first" heaven of the Earth's atmosphere. That is where rain comes from. (Keep in mind: The Bible says there are three (3) heavens. See 2 Corinthians 12:2). This explained in great detail later.
Again, note the contrasting comparison between the phrases the "heavens were of old" (before the waters of 2 Peter 3:5-7) and the "heavens and earth which are now" (after the waters of 2 Peter 3:5-7). If Noah's flood did not alter the upper heavens, then this verse must be speaking about an event other than Noah's flood. And Genesis 1:2 is our only other Biblical candidate.
First, let's look at the actual passage. I'll even throw you a bone and use the KJV.
"5For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:
6Whereby the world that then was, being overflowed with water, perished:
7But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men. "
As we can plainly see, verse 5 is not the flood and verse 6 is. Verse 6 does not mention anything about the heavens being destroyed, only the earth. As for "the heavens which are now," they need to finish the sentence. He's talking about the same old heavens. The "now" only refers to their ultimate fate, being judged by fire.
I'll continue this after church if I need to.
