Before the sun and the stars there was light from God, just as He will illuminate the New Earth.
Revelation 21:1-2, 23 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.….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.
There are two fluids involved. One fluid is light the other is darkness; these two do not appear together Genesis 1:3-4. Another type of illumination, other than the sun and moon which provide light by day and night respectively Genesis 1:14-15, is the Shekinah or Glory of God which guided The Israelites out from Egypt Exodus 13:21 and also appeared in The Temple on occasions I Kings 8:10-11 once it was built. This is not reliant on the sun as an energy source.

Satan is able to simulate radiance but it's false. A deception. Satan is not the sun because Satan has not been appointed to provide light for us. That's clear from Genesis. Satan can nevertheless transform himself as part of his deception.
II Corinthians 11:14-15 And no marvel; for Satan himself is transformed into an angel of light. Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
It's a long term plan but doomed to futility and ruin, along with all those who reject love of The Truth and get deceived (remember that Eve's crime was to have been deceived) resulting in damnation. God is clear on this point:
II Thessalonians 2:7-10 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: even him, whose coming is after the working of Satan with all power and signs and lying wonders, and with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
I hope that is helpful.
