Stupid post.
Writing was invented in Africa and later in Egypt, and had nothing to do with you. It was later on Phoenicians who standardized alphabets for the first time.
First irrigation system was built on Nile river. Had nothing do with you. Those people were living in Africa and speaking a different language and followed different customs than your ancestors.
Wheel in all probability was invented on steppes of Eurasia with its depictions still surviving on stones. It was not by your ancestors.
Astronomy was invented in Africa and much improved on by Greeks.
Literature? You gotta be kidding me. Ancient Chinese, Indian, Roman and Greek literature are rich and powerful (even today). Arabic literature came much later and its impact is negligible.
Division of time into minutes and seconds was done in Africa and Egypt by people who had no connection with your ancestors.
These tales that you create for yourselves are funny to the rest of the world. Only you can take them seriously.
This is what Ibn Khaldun after his extensive research writes of your ancestors:
"Bedouin Arabs dominate only of the plains, because they are, by their savage nature, people of pillage and corruption. They pillage everything that they can take without fighting or taking risks, then flee to their refuge in the wilderness, and do not stand and do battle unless in self-defense. So when they encounter any difficulty or obstacle, they leave it alone and look for easier prey. And tribes well-fortified against them on the slopes of the hills escape their corruption and destruction, because they prefer not to climb hills, nor expend effort, nor take risks. Whereas plains, when they can reach them due to lack of protection and weakness of the state, are spoils for them and morsels for them to eat, which they will keep despoiling and raiding and conquering with ease until their people are defeated, then imitate them with mutual conflict and political decline, until their civilization is destroyed."
