Who invented Writing?

So I was studying for my CCIT exam and I came across an article by Andrew Robinson on "The Origins of Writing"  in my textbook.
Robinson professes that scholars do not know how writing emerged. Theoretically, it originated from pictographs (pictograms, pictorial representations of concrete objects). Others believe that writing was the result of a conscious search by an unknown Sumerian individual in the city of Uruk (biblical Erech), in about 3300 BC. Still some others hold that writing was  the work of a group, presumably of clever administrators and merchants. A few think that writing was not an invention at all, but an accidental discovery. Many regard it as the result of evolution over a long period. Once invented mysteriously, writing diffused all over the globe.

Peculiar isn't it? Secular scholars cannot explain who invented writing yet it exists somehow and it is essential to our life. Written words encompasses everything that we do. Can you think of a packaged food item that did not have a written label or a textbook without words? A blank street sign or a nameless CD cover? Writing is pragmatic, educational, emotional and entertaining. We are in need of it to survive as civilization but we do not have the slightest idea of who made it and how it came to be. Its like waking up and finding a blank cheque next to your pillow. Sure, you are grateful but who should you thank?

Allah says,

الرَّحْمَـٰن عَلَّمَ الْقُرْآن خَلَقَ الْإِنسَانَ  عَلَّمَهُ الْبَيَانَ 

"The Most Merciful. Taught the Qur’ān. Created man. [And] taught him eloquent speech." [Qur'an, 55:1-4]      

اقْرَأْ بِاسْمِ رَبِّكَ الَّذِي خَلَقَ  خَلَقَ الْإِنسَانَ مِنْ عَلَقٍ  اقْرَأْ وَرَبُّكَ الْأَكْرَمُ الَّذِي عَلَّمَ بِالْقَلَمِ عَلَّمَ الْإِنسَانَ مَا لَمْ يَعْلَمْ    

"Recite in the name of your Lord who created – Created man from a clinging substance. Recite, and your Lord is the most Generous – Who taught by the pen – Taught man that which he knew not." [Qur'an, 96:1-5]

It is Allah's mercy that He created us and fashioned us gracefully. Aligned our limbs in all the right places and proportioned our features with just measurement. Each aspect of the human body, from the internal complex network of organelles to the external balanced and steady appearance, attests to Allah's magnificent planning and wisdom. Not only Allah created our being perfectly from an imperfect substance but Allah also animated our cells with life, energy and movement.  Allah placed light in our eyes, enabled our ears to hear sound and our skin to feel and sensor. Verily, only a true God can endow His creation with such astounding strengths and faculties. 

Apart from life, literacy is another great blessing from Allah. Allah created us and taught us how to speak. Allah taught us the use of pen and taught us how to read. Knowledge, in and of itself, is a tremendous bounty and enormous favour of Allah. Can anyone fathom the advancements we have made and the discoveries we have achieved in mathematics, astronomy, geography, marine biology with knowledge? From the electricity to running water, from refrigerated food to, coats and mittens, engine for a car, gas for fuel and park for leisure, are all gift of knowledge which Allah has given us.  

And the finest of Allah's blessing, the matchless bestowal, the ultimate gift is the Qur'an.
