Apostate prophet disagrees with 7th century science; is the Quran unscientific?

In answer to the video "Walking Away From Islam"

The Quran was revealed in the backward milieu of pre-Islamic Arabia, it nevertheless repeatedly calls its audience and readers upon reflection and observation of every aspect of creation, most often the universe, in order to increase in spirituality, not in scientifc discovery.

It is not one of the Quran’s goals to tell everything about the universe; its main goal is to guide its audience to the apparent significances that they can see with their eyes and feel. This is why the Quran only speaks of the apparent significances like the sky, earth, mountains, sun, moon, clouds and so on.  Whether we look at nature and the universe according to ancient beliefs or in light of the latest discoveries, our appreciation and awe of these phenomena, how they are regulated and preserved, is not diminished. Regardless of what we may call these laws, they continue to serve as evidence of the truth and of God’s power which is manifest in 

3:190"the creation of the heavens and the earth and in the succession of night and day".

This not only pertains to astronomy but other aspects of the observable nature. The Quran addresses these things with just enough depth to be relevant spiritually, while maintaining a neutral wording so as to avoid either confirming or blatantly rejecting the scientific notions of the ancients. The Quran was not sent to clear their misunderstandings, rather to clear their ignorance of the higher realities of our existence, and which are present in every aspect of nature

2:115"so whichever way you turn, there is the Face of Allah".

It would have been counterproductive for the Quran to blatantly mention unknown science facts. It carried the risk of deflecting the audience's attention from the deeper message, confusing them further during the delicate process of spiritual reform. Early Muslims appreciated the spiritual portents of these verses but were then free to delve deeper into the unintended scientific aspect, interpreting it in accordance with their own views. We do the same today and others will continue after us, the more scientific advancements are made.

To the spiritually aware, for whom all observation of nature is seen through the prism of God-consciousness, these advancements are simply unravelling further God's might. Islamically, this is the correct approach to all scientific endeavor. When devoid of the spiritual angle, observation of nature only scratches the surface of reality 

30:7-8"They know what is apparent of the worldly life, but they, of the Hereafter, are unaware. Do they not contemplate within themselves? Allah has not created the heavens and the earth and what is between them except in truth and for a specified term. And indeed, many of the people, in [the matter of] the meeting with their Lord, are disbelievers".

All Quranic facts are absolute, and non falsifiable which isnt the case for most scientific facts, because they are the evolutionary product of the human mind as it goes from the primitive to the complex. In the course of human search of knowledge, previous postulates evolved from a speck of truth, to half truth to certain truth then many times only to revert back to ignorance. Most of what we knew, know and will know as science facts always prove in the course of time to be transient.

That is why the modern trend of seeking science "fact" or "errors" in the Quran, while science itself is undergoing an evolutionary process through the human medium of reasoning, is a fundamental mistake in approaching the meanings of the Quran.

This book doesnt need its “credibility” enhanced by means of technical, mathematical, or quantitative data. The Quran is an integrated and consolidated whole that is in no need of scientific confirmation, while science is in need of constant substantiation as it keeps moving from one theory to another. Finite man will never be able to produce infinite science; man will never be able to produce eternal facts.
