PIE

Does anybody doubt where Semitic people came from? Not really - it's the fertile crescent, linguists say it's Levant/Mesopotamia. Where did Indo-Europeans came from? That's the mystery! Current scientific consensus says they came from North of Caspian Sea yet there are still debates, too much politics involved. Somehow the Indo-Iranian roots of Indo-Europeans are not obvious for the scientists. It's imperative for the origin to be somewhere in Europe. East-Europe. Very-East Europe but still - Europe. How would they stay Indo-European otherwise? Also Proto-Indo-European (aka PIE) language is a convenient way to hide the actual Iranian/Mesopotamian origins of even the most basic European words, which would expose Semitic/Persian colonization in Dark Ages.

EXAMPLE #1: A root of navigation and navy. Official etymology: from Proto-Indo-European *néh₂us, cognate with Ancient Greek ναῦς naûs ... Armenian նավ nav ... Persian ناو nâv ... Sanskrit नौ nau. Cool, so we are all related, right? They admit it! Here is the catch. They make it look like the word is so ancient, we don't even know where it came from and why. It happened in prehistoric times. The truth is it's an old Persian word. In all languages it means boat/ship, but in Persian: anything long and hollow ... pipe ... gutter ... channel, canal, aqueduct ... trough ... the sluice of a mill-dam ... furrow or groove down the middle of a man's back or the loins of a horse ... passage through which the meal or flour runs when grinding. In Persian it has generic non-boat/ship-related meaning which also fits as description of primitive dugout canoe or wrapped animal skin boat. Every other people (Greeks, Armenians, Indians) borrowed word from Persian. There was no PIE-origin.

EXAMPLE #2: -burg, the ending of many European city names. Official Proto-Germanic etymology: burgz ... from Proto-Indo-European *bʰérǵʰs "something high up and fortified". Latin one is a little more honest: burgus (originally) A fort or castle, especially a smaller one; a watchtower ... Ancient Greek πύργος púrgos ... earliest Arabic burj. The truth is not in the middle, the truth is to the East. The word is obviously of Persian/Arabic برج burj origin since it has extra meanings in both: steeple/pinnacle/tower/pylon/keep/fort/castle/star/zodiac. But how is tower/keep related to star/zodiac? Does Arabic answer that quesion? No. Persian برز borz does: tall/high/lofty. Which has few other relatives in Persian, such as بلند boland tall/high/loud and بالا bala up, etc. It's definitely not a borrowing from Semitic languages. Now is there a chance Greeks and Germans independently came up with their purg/burg? There is, but in that case we should be seeing related meanings, as many as we see in Persian. I found berg (mountain) in German and that's it.

EXAMPLE #3: Street. Official Latin etymology: from Latin strātus, past participle of sternō ("stretch out, spread, bestrew with, cover, pave"). Why not Middle Persian srat/slt (page 76) from Ancient Persian Sumerian 𒂊𒁍 esir or 𒋻 sila?

EXAMPLE #4: King. Official German etymology: konung/kenig. Which explains nothing. Why not Middle Persian vengeful kenig (page 51)? This would explain a lot. I think Persian Empire was a little bit bigger in medieval than they draw it in Wikipedia.

EXAMPLE #5: Origins of medieval German ship cog and Spanish carrack and Latin carabus plus some explained here.

EXAMPLE #6: Origins of medieval German god Tyr plus some explained here.

Some acknowledged Persian/Arabic origin words: kiosk, paradise, magus.

NON PIE-RELATED

EXAMPLE #1: Innuit ᖃᔭᖅ kayak boat is a well known borrowing in many languages. There is a Turkic word قایق kayik boat. Officially Innuits and Turkic are not related. Not even close. It gets better. Old Persian word for ship was kshtyg/kshtyk, they eventually dropped the last sound so it's keshti now. I think Turkic people had no problem switching the middle sht to y since they turned baghatur/bahadur into bayatur/batur. This would mean transition of some Native Americans into Americas not so long ago. Persians only made it to China 1500-2000 years ago at best.
