Quite!
God is outside of time. Quite. So why would He even think twice about letting the universe unfold over billions of years? Billions of years or six days make no difference to him. Factor in the relative nature of time and the observed nature of the universe and it is obvious that He did not create it six thousand years ago during a six day period. It doesn't matter to Him anyway, right?
Furthermore, if you read the bible literally like you claim we must, how then do you explain the following:
I Samuel 2 starting at verse 8:
He raiseth up the poor out of the dust, and lifteth up the beggar from the dunghill, to set them among princes, and to make them inherit the throne of glory: for the pillars of the earth are the LORD'S, and he hath set the world upon them.
Clearly, by your logic you MUST read this verse as the earth being placed on pillars.
Or what about: Isaiah 40:22:
He sits enthroned above the circle of the earth, and its people are like grasshoppers. He stretches out the heavens like a canopy, and spreads them out like a tent to live in.
Even if you read this in Hebrew it becomes clear that the circle is indeed a coin like circle, not a ball. So again. The world MUST BE FLAT.
Add to that Job 37:18
can you join him in spreading out the skies, hard as a mirror of cast bronze?
and it is clear that a literal interpretation of the bible leads to belief in a flat world built upon pillars with a hard, forged sky above. We know all the above to be false. So either:
a: the bible is wrong
b: the bible is not meant to be read that way.
I opt for b.
Especially given my experiences which dictate that God must exist. Yet also clearly illustrate that a literal interpretation of the bible is both harmful and inconsistent with reality.
