Ok, in 500 BC some people from Gothland (R1a-R1b hybrid) in the north of Europe came to Gotvand (R1a-R1b hybrid) in the southwest of Iran, bought many objects and came back!
It is not my fault that Europeans are not interested to research about the origin of Germanic people, of course we see some incomplete works, like "In Search of the Gods, Scandinavian Ancestry" by Norwegian ethnographer Thor Heyerdahl:
"We learn of the line of royal families in Denmark, Sweden and Norway. But we didn't take these stories about our beginnings seriously because they were so ancient. We thought it was just imagination, just mythology. The actual years for the lineage of historic kings began around the year 800 AD. So we learned all the kings in the 1,000 years that followed and did not interest ourselves in earlier names.
But I remember from my childhood that the mythology started with the god named Odin. From Odin it took 31 generations to reach the first historic king. The record of Odin says that he came to Northern Europe from the land of Aser. I started reading these pages again and saw that this was not mythology at all, but actual history and geography.
Snorre, who recorded these stories, started by describing Europe, Asia and Africa, all with their correct names, Gibraltar and the Mediterranean Sea with their old Norse names, the Black Sea with the names we use today again, and the river Don with its old Greek name, Tanais. So, I realized that this has nothing to do with the gods who lived with the Thunder god Thor among the clouds.
Snorre said that the homeland of the Asers was east of the Black Sea. He said this was the land that chief Odin had, a big country. He gave the exact description: it was east of the Black Sea, south of a large mountain range on the border between Europe and Asia, and extended southward towards the land of the Turks. This had nothing to do with mythology, it was on this planet, on Earth.

Thor Heyerdahl in 1994 at the Gobustan caves in Azerbaijan. He believed these rock carvings of boats which date back to the 3rd millennium BC were created by the Germanic people.
