"It is different from a regular account because God chose to tell us the story in His way. Why He chose to tell the story in such a way is not a question that we are authorised to ask."
Not taking into account the inherent flaws in that statement (as well as what you're talking about), then Genesis has even less credibility than a fairy story.
'We must question the story logic of having an all-knowing all-powerful God, who creates faulty Humans, and then blames them for his own mistakes.'
-Gene Roddenberry (creator of "Star Trek")

McCoy: 'Dear Lord. You think we're intelligent enough to... suppose... what if this thing were used where life already exists?'
Spock: 'It would destroy such life in favor of its new matrix.'
McCoy: 'Its "new matrix"? Do you have any idea what you're saying?'
Spock: 'I was not attempting to evaluate its moral implications, Doctor. As a matter of cosmic history, it has always been easier to destroy than to create.'
McCoy: 'Not anymore; now we can do both at the same time! According to myth, the Earth was created in six days. Now, watch out! Here comes Genesis! We'll do it for you in six minutes!*'
Spock: 'Really, Dr. McCoy. You must learn to govern your passions; they will be your undoing. Logic suggests...'
McCoy: 'Logic? My God, the man's talking about logic; we're talking about universal Armageddon! You green-blooded, inhuman...!'

*- If 'God' was as 'omnipotent' as claimed, why six days? Why not six hours, six minutes, six seconds or six nanoseconds? Now you see the flaws inherent in Biblical thinking.
