This is an edit of my post since my premise was wrong. The verse in question was mistranslated in a manner more concerning than the difference of understanding by translators regarding ataa and yakun.
I'm editing this after going back and reading your original post.
The verse is not a statement but a question, a call to ponder.
It doesn't say "inna" but "hal".
It's clearly wrong without even a shadow of doubt, .
Re: ataa
There are other statements in the book of Allah such as
ataa amr Allah
Hal ataaka hadeeth
Hattaa ataana al yaqeen.
The translations of the first example vary widely depending on the understanding of the sentence.
أَتَى أَمْرُ اللّهِ فَلاَ تَسْتَعْجِلُوهُ سُبْحَانَهُ وَتَعَالَى عَمَّا يُشْرِكُونَ {1

The Event (the Hour or the punishment of disbelievers and polytheists or the Islamic laws or commandments), ordained by Allah will come to pass, so seek not to hasten it. Glorified and Exalted be He above all that they associate as partners with Him.

Allah's commandment will come to pass, so seek not to hasten it. Glory be to Him, and highly exalted be He above what they associate (with Him)!

The commandment of Allah will come to pass, so seek not ye to hasten it. Glorified and Exalted be He above all that they associate (with Him).

:
GOD's command has already been issued (and everything has already been written), so do not rush it. Be He glorified; the Most High, far above any idols they set up.
016:001 Sarwar
:
God's help will certainly support (the believers), so pagans do not (seek) to hasten it. God is too Glorious and Exalted to be considered equal to idols.

Allah's commandment has come, therefore do not desire to hasten it; glory be to Him, and highly exalted be He above what they associate (with Him).

The decree of ALLAH is at hand, so seek ye not to hasten it. Holy is HE and exalted far above all that which they associate with HIM.

(Inevitable) cometh (to pass) the Command of Allah: seek ye not then to hasten it: Glory to Him, and far is He above having the partners they ascribe unto Him!
Allah knows best what the verse from al insaan means, when I first read it, it read as a soothing to the prophet :saws: and a reminder of Allah's mercy and favour to man, however, the verses of Quran do tend to question the mind of the reader through different angles depending upon their circumstances, just as the verses revealed directly addressing the prophet also make us think when we read them or hear them in salaah.
Although I am human and could possibly be mistaken in my understanding (though I have a duty to read it in the language I understand best) and I am required to be sincere in my interpretation.....otherwise I will be the first to go astray. And Allah knows best.
I don't think understanding a language is a sign of understanding Allah and possesing 'aql or taqwa, although it is certainly useful to understand Arabic since it makes understanding the original texts easy without having to rely on and trust the readings of others as a blind mufti or illiterate man would despite his high intellect.
The story reported about imaam Abu Haneefa who was said to have been sitting in halaqah when a scholar of hadeeth narrated a hadith he didn't know is more appropriate, when a woman came and asked a question which the others couldn't answer, Abu haneefa answered it, when the scholar of hadeeth asked him how he had arrived at the answer (he may have had a feeling from the sequence of events) Abu Haneefa is reported to have said: from the hadeeth you just narrated earlier.
The knowledge of the topic was with one person whereas the 'aql to interpret it was with another.
(I found this interesting article as I was searching for a quote on the above which I couldn't find:
https://sunnahmuakada.wordpress.com/2013/01/26/the-knowledge-of-abu-hanifa-and-its-sources/ )
So the argument that the individual lacked Arabic and relied on testimony of individuals whom he trusted (if he was being sincere) doesn't refute his answer - but the facts might.

Regarding the claim that the theory is kufr, what do you base it on, and would you also hand over the hypothesis that the earth was a rough sphere to kufr maybe a thousand years ago or a little less if someone (Such as ibn Taymiyyah - labelled "the heretic from Harran" by some of his numerous detractors) stated it?
What makes you believe that the earth is spherical?

O you who believe! Stand out firmly for justice and fairness as witnesses to Allah, even though it be against yourselves, or your parents, or your kin (and or close ones), be they rich or poor, Allah is a Better Protector to both. So follow not the lusts and vain desires lest you may avoid justice, and if you distort (your witness) or refuse to give it, then (know that) certainly Allah is Ever Well-Acquainted with what you do
