I agree with you that a lot of people are searching for the why of their existence. Some find it in religion. Some find it in other belief systems. I guess I am just a person who doesn't ask "why do I exist?", I just exist and go from there.
Personally I didn't approach my decision to accept the Christian faith to answer the question "why do I exist". It was more a search to figure out just what it was that I believed to be the truth. There not much point in being a Christian if it isn't based on truth. As we can't prove or test our faith in the manner of a scientist in the physical world, we are left with more philosophical ways of finding truth, and it is different for each individual. In the end I became a Christian because I believed it to be true. Years later I am more convinced than ever.

Are a group's beliefs in the importance of their existence a justification to teach those beliefs to others, especially if that group believes that all of existence depends on their viewpoint?
I think that with your whole paragraph taken in context the key is the difference between the justification of trying to teach and trying to impose. Freedom and free will are a critical part of Christian doctrine that often seems to be overlooked.
