What is culture? Well according to the Britannica Concise Encyclopedia, it is the "Integrated pattern of human knowledge, belief, and behavior that is both a result of and integral to the human capacity for learning and transmitting knowledge to succeeding generations. Culture thus consists of language, ideas, beliefs, customs, taboos, codes, institutions, tools, techniques, works of art, rituals, ceremonies, and symbols. It has played a crucial role in human evolution, allowing human beings to adapt the environment to their own purposes rather than depend solely on natural selection to achieve adaptive success. Every human society has its own particular culture, or sociocultural system. Variation among cultures is attributable to such factors as differing physical habitats and resources; the range of possibilities inherent in areas such as language, ritual, and social organization; and historical phenomena such as the development of links with other cultures. An individual's attitudes, values, ideals, and beliefs are greatly influenced by the culture (or cultures) in which he or she lives. Culture change takes place as a result of ecological, socioeconomic, political, religious, or other fundamental factors affecting a society. See also culture contact; sociocultural evolution."
I am a fan of the big bang theory, and Charles Darwin's theory of evolution. What this means is that the various species that thrive on the planet earth, all of which have a certain mode of communication, must have developed to a point where they recognized their own special and unique abilities which formed the basis for their particular CULTURE, before finding LANGUAGE, which is essentially the ability to identify and communicate with your immediate neighbor. If people cannot co-exist with one another over a an extended period of time, they would not be able to develop a language.
Culture is that thin red line that forms the boundary of nations, groups, peoples,ideologies and beliefs, while language is the glue that holds each cultural unit together. If you cannot form a boundary of species with a set of common beliefs, you cannot develop a language. This is why peoples of the world have been virtually at war since the beginning of human history as we know it. The second world war is a case in point.
Before Hitler came to power, there were no such things as Aryan race, or swastika, or the SS. First he had to create a CULTURE of people who believed in some very extreme ideas, and then he went on to define the language and symbols by which they will operate.
Another example is the culture of stock traders. First came the evolution of groups of companies with shares to sell which led to the invention of the stock exchange, which gave birth to the culture of stock traders, who then invented a dizzying array of technical terms that will make the uninitiated totally disillusioned.
Finally, the Egyptians would not be the Egyptians, but for the fact that, they recognized and identified one another over a period of several thousand years, by means of drawings on walls, which eventually developed into the Hieroglyphics mode of communication.
