Culture: Is created by men. The entirety of behavior imbues values and
norms of culture; the language, art, spirituality, religion, politics,
economy, and technology. Also making the landscape liveable by
cultivation. Culture is man-made, opposite of nature (what already
existed before the interference of mankind). With all these
"characteristic" behaviors and methods local traits/features became a
trademark for tribes/populations, which amplifies differentiation and/or
enforces unity amongst the tribe/population.

*Sidenote: Culture is submissive to mutation and can be influenced
easily once carriers of one culture get in contact with the next carrier
of another culture.

The essence of Culture: It holds your identity as culture is the
gatekeeper of history.
