I saw this video posted on a Christian forum I just joined. I do not know the Qur’an so I cannot refute it.
I believe that any truthful person who removes biases from themselves will see that the Quran does contain scientific errors after reading the link provided.
No the Quran does not have errors. We do have errors in our understanding.
"They must...approach reverently and with a mind purged from preconceived ideas the study of the Qur'án which, apart from the sacred scriptures of the Bábí and Bahá'í Revelations, constitutes the only Book which can be regarded as an absolutely authenticated Repository of the Word of God." (Shoghi Effendi, Advent of Divine Justice, p. 49)
It is not an easy book to understand and we have been told this;
"It is certainly most difficult to thoroughly grasp all the Surihs of the Qur'án, as it requires a detailed knowledge of the social, religious and historical background of Arabia at the time of the appearance of the Prophet. The believers can not possibly hope, therefore, to understand the Surihs after the first or even second or third reading. They have to study them again and again, ponder over their meaning, with the help of certain commentaries and explanatory notes as found, for instance, in the admirable translation made by SALE, endeavor to acquire as clear and correct understanding of their meaning and import as possible. This is naturally a slow process, but future generations of believers will certainly come to grasp it. For the present, the Guardian agrees, that it would be easier and more helpful to study the Book according to subjects, and not verse by verse and
also in the light of the Báb, Bahá'u'lláh and 'Abdu'l-Bahá's interpretation which throw such floods of light on the whole of the Qur'án." (On behalf of Shoghi Effendi, Directives of the Guardian, p. 64)
Lets look at 2 verses from that link
18:86 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with kindness."
18:90 Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun.
To me this is ties into the close of a religious dispensation, the sun has set when interpretation has muddied the word of God with false ideas, the people now not worthy of carrying the name they profess. This state remains until the rising of the sun of a new dispensation, again amongst these same people, people still caught up in the dogma held when the sun last set. These dogma have no protection against the New Message.
Thus I clearly see these as a Metaphor of deeper meanings, which the passage above (Directives of the Guardian), that says , "that it would be easier and more helpful to study the Book according to subjects, and not verse by verse."
