I don't think that even all educated people are concerned with the origin of their creation. But some people are.
When we are awake our mind always wander here and there to fulfill something without knowing what it actually is. All the materials we get can satisfy us up to a limited period only. But the wandering continues without an end because with the help of present elements/factors the nature can create/is creating myriads of combinations. This wandering will stop only by the knowledge of our self. Great men who realized it said so and the new generation follows them. Those who tried to test it no longer didn't need to ask a counter question...because they were FULLY SATISFIED with it. This truth is deeply rooted in us also.
Does it come down to easing our inescapable fear of death?

You need not used the term -- 'deeper level'. You can simply use--'to know our real nature'. Or to realize the divinity in ourselves.
It is for reaching the highest level that we can attain with our human body. Thus our life's purpose will be fulfilled...not for finding (our life's purpose).
Is it to seek direction/find peace?
It is for the liberation from all bondages FOR EVER. One can also say so--'to find peace'; because it is also possible.

Isn't it sure that you feel you are born here and are experiencing the happiness and sorrows of this mundane world?
When you realize the origin of your creation you become like a roasted seed. And so you won't 'sprout again'....I mean, you won't take another birth. You will also know whether the usage 'origin of your creation' is actually right or wrong.
If you don't know the origin or your creation you won't be able to know even about your past birth or at least about the truth whether your soul is immutable.
See this (Sri Ramakrishna parable):
A salt doll wanted to measure the ocean’s depth. It wanted to be the
first to tell how deep it was. But the moment it got into the water,
