You could add a few more languages to that list like Mongolian and Hungarian. The original language was an ancient form of Korean. A man came from the Tower of Babel, when all the languages the people were speaking were confused to Korea. However, what was Korea then was not just on the peninsula. It was up in China, Manchuria, Mongolia, and even parts of Russia. It wasn’t a country yet when he came, but it soon would be. The story says the man was more civilized than the others. The people who lived there were cave men. The cave men saw that he was more civilized, and they wanted him to make them into human beings like him. The story actually calls the people by different animals names. They were creatures that lived in caves. The man decided to see if any of them could be human. He took a bear and a tiger and put them in a cave. He gave them human food. They had to stay in the cave for a hundred days and eat the human food. The tiger thought it was nonsense, so the tiger left. The bear stayed. After a hundred days, the bear turned into a beautiful woman. (I think, basically, this man was trying to tame these cave men.) When the man from the tower of Babel saw that the bear was actually a beautiful woman, he married her.
The man from the Tower of Babel built his home way up high in the mountains where the others couldn’t get to him. He and the woman had a baby. The baby’s name was Dangun. Dangun grew up in a civilized home, but he understood the people because his mother had been one of them. He had a heart for the people. He began teaching the people. He brought them out of the caves. He taught them to clean themselves up, built houses, plant gardens, eat more civilized, etc. He had an overwhelming amount of good influence. The people loved him and made him their emperor. There is an altar built outside of Pyeongyang in N. Korea that he was supposed to have built to the one almighty, creator, loving God.
Dangun reigned over Korea, China, Manchuria, Mongolia, and parts of Russia. I am not exactly sure how big his kingdom was, but I know it was huge. He continued to teach the people. His kingdom was known as Goguryeo which was the original name for Korea. The people in ancient times knew about this kingdom because it was the most powerful kingdom in the east. The people along the old Silk Road, the trading route between east and west, began calling Goguryeo “Korea” because they misunderstood what the people from there were saying. The kingdom of Goguryeo lasted for 5,000 years until infighting began splitting it up.
When you begin learning Kanji, you will realize that many of the Kanji tell Bible stories like the story of creation and the fall of man. That study is actually pretty amazing. Kanji actually makes sense. The people began drawing pictures to communicate, and the pictures actually evolved. I have been shown the kanji that tell the Bible stories, but I don’t remember them all, but they make sense just like all the kanji do. My Japanese teacher showed me how the original picture they used for “mountains” became the kanji for “mountain,” 山 (yama, in Japanese) how they used to draw “river,” and how that evolved into the kanji for river,川 (kawa, in Japanese), etc. Mouth is just one kanji: 口 (kuchi, in Japaenese), and becomes “language” or “word” 語 (kotoba or go, in Japanese). This kanji for “language or word has a mouth on the bottom with lines above it meaning something is coming out of the mouth, and the other part has a 5 on top and another mouth on the bottom, so “five people speaking” is a language. I have seen people take complicated kanji and pull them apart and show how the were originally telling Bible stories. Kanji is a very interesting study, and it links the people who originally made it up to the Tower of Babel.
The only thing I can say is the language from that part of the world must have originally come from the man who came there from the Tower of Babel when God confused the languages. Either that, or it is a mixture of what he spoke along with what was originally there. Japanese is a mixture of Chinese and the language that was on the islands. There are many overlapping words between Chinese and Korean and some between Japanese and Korean. Kanji links itself to the Bible because each kanji tells its own story, and some of those stories are early Bible stories.
