What is culture? Is is important?

In my opinion, culture is a very important part that all humans have which helps each of us define where do we come from and who were our ancestors. Culture is basically a system of knowledge that is shared by a large number of people. Culture refers to deposit of, experience, beliefs, values, attitudes, meanings, religion, and spatial relations, concepts of the universe, and material objects and possessions acquired by a country or large group of people. It is the way of life of a group of people including the behaviors, beliefs, values, and symbols that they accept. Culture is the sum of total of the learned behavior of a group of people that are generally considered to be the tradition of that people and are transmitted from generation to generation. I strongly believe that having a culture is an essential part of our lives because if we do not have one, we basically have no identity.
