God told us that He created the earth moon and stars and every living creature in 6 days.
No He didn't. He told (perhaps) some people with very limited understanding of the natural world that over 2500 years ago. What He actually said wasn't written down for centuries.
What He has actually written they couldn't read. We now can read what He wrote. We can read it first hand without having oral traditions, translation mistakes and limited background in the physical sciences getting in the way.
He hasn't used human tools to write. He doesn't play with brushes and parchment, pens and paper, printing presses or computers to write his message.
He wrote his message about how He formed the universe, world and life into the rocks, into the stars and into us. We can read this message directly and
He tells us that the old writtings (while ok for the time) are not correct and
He is telling you that you are wrong. You now need to learn to read the language He writes in or suffer in ignorance of the message He tries to deliver to you.
