How was there Light before the Sun, Moon and Stars?

This is an issue that has often plagued theologians, how Genesis 1 has Light created on Day 1 but the sources of Light aren't created till Day 4.

Augustine of Hippo theorized that the Light created on Day 1 was the Angels.  I've seen both Young Earth Creationists and Old Earth Creationists suggest that Day 4 is simply when the Light of the Stars finally reached Earth.

What amuses me is the failure to consider that the answer to this mystery of the first Chapters of The Bible might be found in the last Chapters.

Revelation 21:23-24, 22:5.

And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.  And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honour into it.

 And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.

Remember that Jesus is the Light of the World in John 8:12&9:5 (and the Light was earlier discussed in chapters 1:4-9 and 3:19-21 and later again in 11:9-19 and 12:35-36 and 46) and He was called the Phosphorous(Lightbearer) in 2 Peter 1:19.  This can also contextualize Jesus saying He is The Beginning of the Creation (Revelation 3:14) and the Firstborn of Creation (Colossians 1:15).

Some might seek to use this connection to support an Arian or Semi-Arian Christology, but that's not necessary, even with a completely Nicene understanding of The Trinity it's still simple to conclude that the Word of God is the source of the Light when God Spoke Light into existence.
