There are things in this world God has not explained to us. If he thought it was critical for us to know these things he would have told them to us. However one of the issues being discussed is not a major point for discussion. God has already made known to us clearly what the answer is. God was particular to mention that when he finished creating certain things, the day would end and there would be darkness then light again, then he would create, then there would be darkness and light again. God is explaining the setting and rising of the sun. Although the explanation is more simplistic than the reality taking place , God has explained it to us in a way that a simple man can understand.
I think the lord does want us to know what he knows about all things
Remember we didn't really have a choice in one reguard because mankind gained all knowledge of good and evil. Which the lord wanted to prevent.
Mankind where not suppose to know all things is probably more fitting.
When the earth is destroyed one thing in this earth will still remain
Samuel 2:8 (ESV)
8 He raises up the poor from the dust;
he lifts the needy from the ash heap
to make them sit with princes
and inherit a seat of honor.
For the pillars of the earth are the Lord’s,
and on them he has set the world.
The pillars (are also the foundations) will remain for the new earth to be laid upon.
As these pillars are the lord's.
Something that is the lords is eternal.
But from which point it was eternal remains mystery.
But that doesn't mean to say we don't know, because we clearly do in one regard we understand the mystery
