You're going off topic now. The man posed a valid question, which needs to be taken seriously. Not everything in the Word of God is given to us easily: many times it requires tough work and many Odin's to acquire the information straight from the Bible.
The point of The Creation Week is God demonstrating to us that He is able to create things out of nothing, and to expose our own ignorance of the origins of the world.
God being the Creator and the Light should be proof enough that He made all things. It is important to understand that while light gives us the for of an image: it dies not define whether the image's characteristics (e.g. wet, dry, hot, cold, small, large, etc.): It is the Word which gives the image definition: and it is our senses which inform us that we are interacting with something; while the mind interprets what comes through the senses.
You two should really meditate on the words of Moses and king Solomon:
"The secret things belong unto the LORD our God: but those things which are revealed belong unto us and to our children for ever, that we may do all the words of this law."
-Deuteronomy 29:29
"It is the glory of God to conceal a thing: but the honour of kings is to search out a matter."
-Proverbs 25:2
Everything written in the Bible contains what we need to know, it just effort at times to find certain answers to our questions: and God did this for our benefit that we might receive honour and glorify Him.
