Consciousness implies someone is looking at something and knows they are looking.
Purpose is a direction of consciousness implemented by willful action.
Natural evolution depends on random mutation, and some people believe this proves that consciousness has no higher purpose.
Consciousness is entirely dependant and conditional upon the actions which sustain it (and life).
The primary purpose of consciousness is to direct the living being in insuring the continuance of conditions which sustain its life.
Beyond the primary purpose (stay alive!) a hierarchy of purposes remain; chiefly, improving conditions for sustaining life.
By improving the conditions which sustain life more and more subsidiary purposes become possible.
If you are freezing, starving, in pain or thirsty; nothing else will matter more as a purpose than overcoming those conditions.
If you are comfortable you have more options.
THE HIGHEST purpose of a living being is a completely well-lived life. Consciousness of what creates a well-lived life is the highest purpose of personal awareness and intellect.
What we include/exclude in relation to our life is our purpose.
MYTHS are rough-drafts.
MYTHS were man's first guess scenarios which helped him gain a perspective.
Who am I? Where am I? Who is in charge? How do I avoid death? How can I continue to live better and better?
The MYTH became a community opinion of how things work.
When science and Philosophy came along and Logic became a tool of thought (Greeks) the Myth started to fade.
Why?
Actual knowledge supercedes guesswork and storytelling.
EMOTIONALLY mankind was addicted to their own FEELINGS about their MYTHS and the characters they created.
This is religious sentiment.
Only actual knowledge can drive out the emotional attachment to myth.
