Existence?

[WICKED]

The thing is that I really want to know what people of all of all schools of thought have to say on this subject. Let's face it, your average beleiver (or, for that matter, nonbeleiver) walking down the street has likely never once given existence itself a thought. This egocentric species of ours seems to like to trace events UP TO and including the "creation" of our universe and leave it at that. Why existence exists [a double positive?] is usually left unanswered.
