Alaska...has 6 months of light and 6 month of darkness.
So many things are assumed by the knowledge of such things as this occurrence.
So how bright is the light from the sun does it really reflect off the moon at night?
You see they don't actually know anything when it comes to light and the age as you have described they literally assume. Yes they have many theories not all proven which they use to reach their conclusion but that is it a conclusion not 100% evidence or proof. So we know about the tides, the earth movements and how the moon and sun are said to affect things... But the evidence is lacking...

Give me the point of the light 280 million light years away. Tell me what that source is and do not use the sun or the stars in anyway.
So don't make any remarks about what God may or may not have done since he himself is a source of light. He is the one true light from which everything including our light came. And you have no proof that it didn't. You lack knowledge to support your own claim. Till you can prove your own claims with actual evidence don't tell us what our God can and cannot do. Your science has not yet disproved anything about God. Man assumes he is his own worst enemy.
