Why myths?

We often come across myths as something that's a misconception, something that is untrue. One is considered ignorant if they believe in myths. So, are myths obsolete in today's modern world?
According to Carl Jung, a man is incomplete without his myths. Myths are what he calls the 'biological' truth as opposed to the statistical truth provided to us by science.

Myths are mankind’s creation to help them align their consciousness to the cosmic order of being. They act as pillars of support for the growth and well-being of a community and eventually the whole civilization at large. According to Jung ‘humans need myths to bring them in order to the greater realities of nature’. Myths rather than being moral stories act as guiding points to assess one’s progress and also ways to overcome hurdles in the course of life. Like Campbell says, it is like a patterned mirror to map your progress in the journey of life.
