It's highly unlikely Aristotle was a figment of 'Arab' imagination given the numerous references made by Greeks and Italians prior to what you are referring to as Arab culture.
It's really a matter of wanting to understand as best as the evidence allows for what happened during that time period.
For example, even here you refer to the 'Arabs' preserving some Greek knowledge. However, it was the Persian Emperor
Khosrau I who did the preserving. He was the one who personally accepted refugees from the Eastern Roman Empire when that dick-face Justinian I closed the neo-Platonist schools in Athens in
529. Khosrau's the reason why Greek knowledge was saved - not some nondescript 'Arabs' (whom ever they are). He was the one given the title “
Plato's Philosopher King” by the Greek refugees and he was the person who encouraged an interest in Platonic philosophy. He build a massive library for Greeks to study and learn in. So, if you want to credit someone, then give credit to where credit is due.
It's like you're so wrapped up in Islamic mythology you have absolutely no idea or interest in the real history of the 6-7th century CE. I suppose some people prefer to live life believing fantasy stories instead of trying to learn the real History?
It's fine to study 8th century Arab historians - just know that much of what you're reading as 'History' was completely made up for Religious/Political purposes.
From
WIKI:
Khosrau I laid the foundations of many cities and opulent palaces, and oversaw the repair of trade roads as well as the building of numerous bridges and dams. During Khosrau I's ambitious reign, art and science flourished in Persia and the Sassanid Empire reached its peak of glory and prosperity.
He reformed the Military and He reformed the Law and it was he who fought against the Byzantium Empire.
Not surprisingly we have coins minted during his rule:
There's plenty of contemporary evidence for the existence of Khosrau I, Alexander III, Qin Shi Huangdi, Genghis Khan, Julius Caesar.
Is there ANY contemporary evidence that Kahlid exited at all? What cities did he found?
If there's ZERO contemporary evidence then it's more than likely he was completely made up in the style of a Greek Hero myth. I think if that's the case, we should acknowledge that and try to find out what REALLY happened during that time period.
Who were the other main 'Arab' leaders of the time? Who else could have lead all these armies in battle... if such a thing actually happened.
- We now have actual minted coin contemporary evidence of the word Mohammad being used as a title of Jesus.
- We have evidence of Christians and other Gnostic sects that have identical beliefs to Islam from 100s of year before the supposed existence of Mohammad.
- We have ample evidence of Persian rulers taking Persia to the height of it's prosperity in the 6th century.
- We have ZERO contemporary evidence of Khalid having ever existed.
What we do know is that for some reason there was also a large number of Byzantine Cities whose economies were collapsing. Maybe there was a plague? Maybe Arab nomads simple moved into depopulated cities following a devastating epidemic? The reason why you can't find any contemporary evidence of Khalid may be because he was completely made up so 'Arabs' could take credit for Khosrau I.
WHY was Ctesiphon, the imperial capital of the Persian Sassanids abandoned and Baghdad built 30 miles north? WHO built Baghdad? I can tell you it probably wasn't Arab Nomads. Supposedly they even had to pay Christian engineers to drain Mecca of swap water, that's how little knowledge nomads have of building cities. Who paid for this city being built? How did 'Arabs' come to find themselves in charge of it?
