So the moon is a created light and does not reflect the light of the sun. Because that is what Genesis 1 is saying God created two great lights (sun and moon) and not a great light and a great light reflector
That has nothing to do with the shape of the earth.
My position is that I agree with the late John Stott who said; "the Bible tells us THAT God made the earth. I tend to believe it's the job of scientists to tell us HOW."
Genesis does not tell us HOW God created - how he made ladybirds chaffinches, owls, whales, hippos, eagles, worms etc. Or how he decided some creatures should have feathers and others fur or scales. Or how he made the sun and what its properties are - etc etc. It is not a science textbook; its purpose is not to go into scientific detail.
God made the world - GOD. It was not made by angels, cherubs or a god, nor was it a chance result which happened when 2 atoms collided. The world has a maker.
I've been out walking this afternoon. It's a bit windy but the sun is shining, the bluebells are out and trees are covered in delicate blossom. Birds are singing; I had hoped to see a kingfisher, but didn't.
The world around us is beautiful - and as someone has said, we can say "my Dad made that!"
And yet it seems that all we Christians can do is argue
with each other about the nature of that creation, how exactly God did things. If something is not mentioned in Scripture, apparently it didn't happen;. If someone doesn't believe a verse literally, they are doubting Scripture etc etc.
It's true what they say about the devil not needing to attack Christians - we do that ourselves.
