LOL, you are such a coper. At first, Germanic doesn't equal Aryan. Aryan MEANS (when it comes to language) Indo-European (so not only Germanic, but also Latin and it's offspring, Slavic, Baltic, Celtic, Persian, Indian and bunch of extincted branches like Tocharian and Anatolian) or (when it comes to appearance) blonde-haired and blue-eyed people. But Aryan appearance didn't come with Aryan language. At first Aryans were short, massively built redheads with reddish skin. Therefore they were called Red Nordids (RN or Ancestral North Eurasian). The blonde people, who inhabited Europe before them were White Nordids, athletic built blondes with pale skin (WN or Western Hunter Gatherer). The so-called "Aryan" appearance comes in fact from them. And, in opposition to your silly belief influenced by (((Hitler))) they weren't Germanic. Germanic is mixed language who came from mixing between early Balto-Slavs (itself mixed nation between ANE and WHG), early Celts (itself mixed nation between EEF associated with Armenid race, ANE and some WHG) and remains of White Nordids who escaped to isolated Scandinavia because of EEF and ANE invasion. WHG look became base of looks in Scandinavia, because every invading nation had a strong WHG component in itself and they mixed with native WHG's. Climate there also helped in preserving blondism and WHG heritage (but we should notice that we have also ANE influence in new-founded community showing itself in red hair and EEF influence showing itself in black hair, although WHG is dominant). But it is only due to Scandinavian living conditions and it doesn't apply to modern continental Germans (who can't be spotted because of looks in the masses of thier neighbours like northern French or Poles). Germanic language is only a side-effect of Indo-Europeans attacking Scandinavia. A new nation arisen in Scandinavia (who became fully German in modern sense by having a lot of Finnish influencies. Finns are also good example debunking your theory about Germans being forefathers of light hair, because even Finnish tribes living as east as Urals, where Germans in modern sense were never present have a lot of blonde hair. Another example are Berbers of North Africa, who were called blonde-haired during the time of existence of Egyptian Old State, when any Germans weren't present in the neighbourhood) however, started they expansion. They needed to surivive. So they started to pillaging and settling on the continent. Therefore, they conquered modern-day Germany (from Celts) and started to settle in immense terrain, which we call now Eastern Europe. And they mixed with natives. But climate here wasn't as helpful as Scandinavian in preserving blonde (and red) hair, so it decreased it's numbers (not dependent on language, which the population spoken it started even before Slav invasions) but not drastically. WHG genes were also present in natives, so we have many blondes (but not as much as in Scandinavia) in EE. EEF genes had increased their numbers, because Germans had them in their gene pool and they brought some new from Celts. And they continued to live that way (managing even to create "empires" like Hermanaric's state) to the time when Hunns came to Europe. Slavs (RN's with WN influence) came after Hunns.
