I think you misunderstood. The verses you referred to are for those who don't believe of the existence of God.
I think you were referring to the verses that I said are scientific miracles no ?
36:77 Does man not consider that We created him from a [mere] sperm-drop - then at once he is a clear adversary?
21:30 Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?
78:7 And the mountains as stakes?
25:53 And it is He who has released [simultaneously] the two seas, one fresh and sweet and one salty and bitter, and He placed between them a barrier and prohibiting partition.
21:33 And it is He who created the night and the day and the sun and the moon; all [heavenly bodies] in an orbit are swimming.
21:30 Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?
39:6 He created you from one soul. Then He made from it its mate, and He produced for you from the grazing livestock eight mates. He creates you in the wombs of your mothers, creation after creation, within three darknesses. That is Allah , your Lord; to Him belongs dominion
None of the above are miracles.
Islamic websites promote miracles in the Koran, but this is just to convince the ignorant and gullible people.
For example lets look at one of your verses you have presented as evidence of a miracle:
21:33 And it is He who created the night and the day and the sun and the moon; all [heavenly bodies] in an orbit are swimming.
When the Koran was revealed it was commonly believed that the sun travelled around a stationary earth They had a geocentric understanding of our solar system. So this verse would've have not have surprised people back then as this is what they already believed.
So was the Koran referring to 7th century ignorance or modern science when it claimed the sun moved in an orbit:
031.029
PICKTHAL: Hast thou not
seen how Allah causeth the night to pass into the day and causeth the day to pass into the night,
and hath subdued the sun and the moon (to do their work), each running unto an appointed term; and that Allah is Informed of what ye do?
These were all visible phenomena to the people of the 7th century, they could 'see' the night turn into day and vise versa, they could see the sun and the moon run their courses around the earth. Just like you can if you look up at the sky and see the apparent movement of the sun.
013.002
Allah is He Who raised the heavens without any pillars that you see, and He is firm in power and
He made the sun and the moon subservient (to you); each one pursues its course to an appointed time; He regulates the affair, making clear the signs that you may be certain of meeting your Lord.
Again, the above verse claims the course the sun(and moon) take, are clear signs of Allahs existence. Once again confirming a geocentric solar system to its revealed audience.
36:37/38/39
PICKTHAL:A
token unto them is night. We strip it of the day, and lo! they are in darkness.
And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. And for the moon We have appointed mansions till she return like an old shrivelled palm-leaf.
The above verse explains that as night appears, earth becomes dark and the sun runs to its resting place and completes its course. Which again confirms the suns 'course' is related to day/night and confirms a geocentric understanding people held back then.
Although no further clarification is needed Mohammed kindly explains the error in his words:
Book 001, Number 0297:
It is narrated on the authority of Abu Dharr that the Messenger of Allah (may peace be upon him) one day said: Do you know where the sun goes? They replied: Allah and His Apostle know best. He (the Holy Prophet) observed: Verily it (the sun) glides till it reaches its resting place under the Throne.....
So Mohammed tells us that at sunset, the sun runs to its resting place and completes its daily course and once again and confirms the errors in the Koran.
So it is clear that the suns course described by the Koran has nothing to do with the galactic orbit science has recently discovered. Rather it's a confirmation to it's early readers of the misunderstanding they held at the time.
