What are the legends and myths about "ice and snow" in the East and West? The more specific the better.

It is said that Aryans who believed in Zoroastrianism in ancient Iran migrated to West Asia from their distant hometown. Their ancient legends remind people of flood myths of other nations; The similarity between the two is unlikely to be accidental coincidence, and the Aryans in Iran are definitely not the only people with this legend. In fact, although such myths are generally related to floods, in many parts of the world, the story of God enlightening mortals and helping a few people escape from the catastrophe has become a world covered with vast ice and snow.

For example, in South America, the T0ba Indians living in the Great Chaco region, which straddles the borders of Paraguay, Argentina and Chile, still have an ancient myth about the "great cold current" that once came to the world. A demigod hero named Asin warned mankind:

Asin asked one person to collect as much firewood as possible and spread a thick layer of thatch on the roof, because the cold day was coming. After the roof was laid, Asin and the man entered the room, closed the door and waited. The cold days have really come. Neighbors came to their house trembling and borrowed a piece of wood from them to keep warm. A Xin has a heart of stone, and will only give his ashes to people who have had friendship with him. People outside were frozen and crying all night. In the middle of the night, men, women and children fell dead in the snow one after another ... The hail weather lasted for a long time and all the fires were put out. The frost on the ground is as thick as leather.

As described in the Zoroastrian myth in Iran, the cold is accompanied by darkness that covers the sky. According to an elder in Doba, this disaster happened "because when the earth was full of human beings, it had to be changed." In order to save the world, we must reduce the population ... The earth is in darkness, the sun has disappeared, and all people are starving. In order to fill their stomachs, they killed the children to eat. Finally, all the people starved to death ... "
