Some of these words like for example Kafkas, were initially things related with real world. They later were converted into myths in many different cultures by the elite Turks (who many people would identify with evil) who wanted more power for themselves and less for the common Turks (Turk meaning the simple rest of the people in the world). They literally wanted to hide reality from their slaves.
The Greek word for horse is an amalgam of two Turkic words meaning "man-horse" aka: centaur from kentaur from Turkic KenTur meaning "he-it himself-itself is a Tur"
Arhyppei - people akin to the Scythians (Morphologically resembles other Greek monikers Melanchlaen, Hyperborean, “hippo” is horse in Greek; but it could be a Grecicized version for a Scythian word for centaur, as agglutination of Tr. Ar + jaby/yabu/jupax = “man + horse”; the Greek “hippo” horse - is dialectal Türkic “yabu”).
For example the Caucasus was turned into Kaf Mountain.

So in my opinion, some people were eager to hide the "turth" by turning parts of it into some kind of myth. I have many ideas about why they did this. I was curious about your ideas when I started this thread, but I had difficulty convincing you that reality wass converted into myth because people suddenly turned into "Turks could not have done that", "Turks do not belong in ancient history", "I don't even like turkey in my sandwich", etc. So I wasn't able to convince anyone:
Reasons
1: The Turks who were doing the above (Turks could not have done that, Turks were never civilized in the past, Turks did not exist in the past, Turks are not even from Earth, etc) were not good at Turkic languages and they lied about anything I wrote making it seem like I was lying (since nobody trusted me which resulted in everyone trolling each other (I was trolled the most. Some people are very good at it)) about many different words. This is common in Turkey for some time. It's called inferiority complex reaction. There are certain weird clueless people in Turkey who think they can move small mountains, who like to glorify Turkey because of their Ottoman heritage and some of the people who are normal (in my opinion only better than them) like to make fun of them by attempting to scorn "Turkness". This action gains support of Europeans and also people who see Turks as their arch-enemies. (Iranian , Armenian, Kurdish, Greek, Arabic) I'm guessing that the Turks who are against my ideas here are not familiar enough with the subject and confuse me with one of those people.
2: I exaggerated some of the patterns to reach some conclusions.
3: People thought I was a nationalistic person who wasn't after the turth but who was trying to glorify his nation's past. (I still think it's not wrong to do this although I'm not one of those people)
The result is this thread.
