I agree with Autodidact. You claim the Qur'an has no discrepancies, but your only evidence is Surah 4:82, which says no one has found a discrepancy. But as you know, there are several threads on this forum where we have discussed errors/contradictions/discrepancies/inaccuracies in the Qur'an. Usually whether something is an error, or inaccurate, or imperfect or not comes down to a person's subjective judgment.
For example, you and other Muslims usually argue that the meaning is complex or subtle or poetic, or intended for a different audience, or use special pleading, in order to make the problems disappear. If the subtle or poetic language seems to agree with something scientific, then it is literal, however. You pick and choose. With enough imagination, it's always possible to interpret scriptures in a way that makes perfect sense out of them. You can see other religious people doing the exact same thing, with Taoist or Jewish or Christian or Manichaean or Zoroastrian or Hindu or Mormon scriptures.
If advanced intelligent beings wanted to give us information that can be proven to be perfect and without any error, they could send proofs of advanced mathematical theorems. Or they could accurately describe the nature of molecules and all the elementary atoms, how micro-organisms cause disease, what is the diameter of the Milky Way galaxy, or what are the fundamental laws of physics. Or what is the mass of the electron. Or the exact times/dates and locations of sunspots, or several digits of pi around the trillionth decimal. Or how to produce penicillin, how to construct a steam engine or printing press, or how to vaccinate people. That kind of information is truly indisputable, there's no subjective judgment as to how "perfect" or accurate it is.
But apologists will say, oh, that would be too much proof. That would spoil the test of faith. So which is it? Does the Qur'an provide indisputable proof or not?
The most compelling "proofs" from the Qur'an I have seen posted on this forum are (1) it's dark under the water, and (2) a 1 centimeter human embryo looks like a lump of flesh. Wow. Incredible. :sarcastic
And by the way, I have read many chapters which are far more technical than the Qur'an and I do not know of any error or discrepancy within them. The margin for error in those chapters is far smaller and yet I often do not find any errors. And I have read chapters that are like the ones I have read in the Qur'an. In fact, many of them are more clear, accurate, eloquent, useful and true than the chapters of the Qur'an I have read.
