How literally should we take the Qur'an ?

[arewethereyet]

Quran, just like Bible, claims that God created the universe in six days. Earth is created on the first day. Four days later, God creates the sun, moon, and stars.

And why do you consider this to be a mistake? The duration of a day in these verses isn't the one we're familiar with, it could be any arbitrary duration that only God knows, the theist can legitimately argue along these lines.

But there is one thing that doesn't change, even if the durations are disagreed upon: ratios of durations !

With this in mind, some muslim apologists went further and turned the tables, there is a numerical miracle in the verses about creation :

Say: Is it that ye deny Him Who created the earth in two Days? And do ye join equals with Him? He is the Lord of (all) the Worlds. (9)

He set on the (earth), mountains standing firm, high above it, and bestowed blessings on the earth, and measure therein all things to give them nourishment in due proportion, in four Days, in accordance with (the needs of) those who seek (Sustenance). (10)

Moreover He comprehended in His design the sky, and it had been (as) smoke: He said to it and to the earth: "Come ye together, willingly or unwillingly." They said: "We do come (together), in willing obedience." (11)
 
So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. (12) 

[7-9,10,11,12]

From these verses we learn that : 

(1) In the first two days of creation (out of 6): God created the Earth.

(2) In the first four days of creation (which overlap with the first two days above): God bestowed mountains, and various sources of nourishment and blessings.

(3) In the last two days (out of 6): He completed the heavens as seven firmaments. 

The two last statements can easily be misunderstood, especially when the verse is not read in Arabic. The statement (1) however is clear and incontrovertible, it can't be interpreted in any other way, the age of the Earth is 2/6 that of the creation as a whole (e.g. the universe), and 2/6 is 1/3.

We now know that the age of the Earth is 4.5 billion years, and that of the universe is is approximately 13.7 billion years, the ratio 4.5/13.7 (=0.328...) is very close to 1/3.

If we take more decimals in the ratio from available data 4.543/13.787 = 0.3295.., we only get closer and closer to 1/3.

Why wouldn't god create the mountains, nourishments, and whatever the heck blessings are on the same day that he created the earth?  Seems like god is a poor time manager.  

Did (s)he look at the earth and decide it needed lumps?
