Many have looked there but couldn't find the answer. As we search we begin to find that a lot of what we believe to be the answer turns out to be a dead end road. We end up feeling disillusioned about life and want to give up the search. Apathy sets in and we become cold inside. We just don't care anymore.
Humans are basically religious by nature.
We have an overwhelming need to believe in something. Even the primitive natives in the jungles look for the answer. They know God is out there somewhere. They worship Him the best way they know how. We need to know the answer.
