Do you believe that language can influence cultureI asked my friend what separates Indians, Chinese and Burmese. She innocently said borders. It was a great answer but I wanted something metaphysical. Culture and language were the things settled on. I want to ask rest of you, do you think there are other things despite these that denote an ethnic group? Socio economics must not be considered as economic superpowers like Singapore and Saudi Arabia were pretty poorer than their present day a couple of centuries ago. Ofcourse their neighbors can influence them, but that comes under diplomacy. Common populace though, is far beyond these things. All that they are concerned about are their languages and cultures.
Let me give you an example. 4000 years ago, all the area from Hungary to China, from Afghanistan to Russia was occupied by Indo-European language tribes. Iterating what my friend said, culture and language are the basic blocks that denote an ethnic group. Do you think culture could have existed before a language does? Language helps people coordinate, hence is valuable and necessary to form a culture. That is something many archaeologists and anthropologists agree upon.
Back to Indo-Europeans, Indo-Iranian languages came from Indo-European speakers who settled around present day Iran and India. Since we belong to a same language group, we share a similar culture. Zoroastrianism, is almost as old as Vedic Hinduism. Both religions believe that time is cyclic. Both believe that at the end of times a savior would emerge and world would be re-created. Initiation ceremony of Zoroastrianism and Hinduism, is wearing a sacred thread for whole life. Devas and Asuras are present in their pantheon too, but follow a different role. Names of kings of Persia, atleast the Persian names, totally can be mistaken for Indian king's names. Most of all, Iran is a name derived from the word Aryan, the same Aryans that gave rise to North Indian cultures.
