“This story of origins is entirely fiction. But sadly, many people claim to believe the big-bang model. It is particularly distressing that many professing Christians have been taken in by the big bang, perhaps without realizing its atheistic underpinnings. They have chosen to reinterpret the plain teachings of Scripture in an attempt to make it mesh with secular beliefs about origins.”
Genesis is not a science book. It doesn’t explain how the world was created. It is at a much higher level. Thus there is no inconsistency. I doubt we will agree. But i do wish you well.
