Idolizing the Bible seems to me to be largely an Evangelical and fundamentalist disease. It occurs when the Bible -- or an interpretation of it -- means more to people than their god itself. Such as when someone insists that Genesis must be taken literally and cannot be legitimately interpreted metaphorically. To put it in Christian terms, it's making the law more important than the spirit of the law.
The "argument" is disingenuous.
Loving the bible is loving God because it is considered the book of God.
As for Genesis, I presume you mean the creation account?
God first made the heavens
then the earth
and the early earth was dark and oceanic
and then the granite continents rose
and the atmosphere cleared
and life emerged, first on land (in fresh water) and then the seas brought forth life.
and finally, man.
As for The Flood.
The term "earth" or "world" meant differing things to each generation, just as the
term "universe" has shifted in the past 20 years. In Genesis time the world was
the tiny population of the Middle East, later the earth was the empire of the Babylonians
and later still the earth was the Roman Empire (even though other empires were known)
