The incompatibility between Genesis and science is mostly in the order of things. It's easy enough to say that 'day' is a metaphor for 'arbitrary period of time', especially before planets were created.
For example, day one. God creates light, and divides day from night. Now light came into existence 10-12
seconds after the big bang, and days and nights couldn't have occurred on Earth until nearly ten billion years later. That's a long day.
But then on day two, god creates a firmament and divides it into the waters and the skies. Now since water is made mostly from hydrogen and oxygen, and air is made mostly from oxygen and nitrogen, we can equate the firmament with a common precursor. The mass expelled by a supernova that formed the solar nebula is the only way you're going to get large amounts of nitrogen and oxygen. But then god must have made the firmament before making the planet, and before dividing day from night. So the firmament must have been made around lunchtime on day one.
That the order of things in the biblical account of creation is fundamentally wrong is one thing that can't be disguised by claiming it's a metaphor.
