Define literal, even if you ignore the "day" aspect the ORDER of things being created is wrong.
It goes beyond not covering everything, beyond exaggerating, it quite simply is WRONG order.
If Genesis is just a story, which is factually wrong, then why should we not assume that the rest of the Bible is not also just a story, that is factually wrong?
Like I said of Augustine, a 4th century Christian Theologian, states that the six-day structure of creation as told in the book of Genesis represents a logical framework, rather than the passage of time in a physical way. It is a spiritual, rather than a physical meaning.
Using a science based argument to fulfil a philosophical question is a flawed premise in itself, besides the fact that if we logically follow your argument that because one part of the bible is flawed then the entire edifice of Christian belief and the belief in God entirely is flawed, then we must also assume that as Lamarkism the precursor to Darwinism was flawed then Evolution and the entire edifice of science must be flawed.....
Well that clearly is not the case and neither is your argument.
