Why do we need to philosophize?

It's human nature to wonder "Why?" Babies explore anything as soon as they are able, people question everything and want to know how it works, why it works and where it came from. And what "it" is...

Just ask yourself WHY SHOULD I BE HERE? This is the first question that arouses your curiosity and then "WHYs" constantly comes. If its important to you that why do you live here! Just ask it and then try to find the answer!

I find it necessary to here quote the magnificent Kurt Vonnegut, Jr. This is from Cat's Cradle.:

Tiger got to hunt,
Bird got to fly;
Man got to sit and wonder, "Why, why, why?"
Tiger got to sleep,
Bird got to land;
Man got to tell himself he understand.
