What makes KL a civilization

In KL they have shelter(so we don't have to sleep in the outdoors, water(So we don't die of thirst), Food(So we don't die of hunger),transportation(So we don't have to walk everywhere) and technology( We can send email, call people with phones and cell phones etc), KL is also a civilization because KL is a city which works together to survive and thrive. Without those things we might never have KL!
