Why?

One word, so many meanings.
One question, so many answers.
One question? No.
There are hundreds of questions,
you can ask with the little word "why".
But nearly none of the questions are clearly answerable.
Why do we live?
Why do we love?
Why do we die?
Why do we think?
Why do we destroy ourselfs?
Why are we, the way we are?
There are so many questions, but no clear answer...
