You know, the real trick about all this 'existence' stuff and its beginning and ending and such, is that for all intensive purposes, existence began when we were conceived in the womb, and it ends when we die. All we have is what we learn and experience to tell us otherwise...history built on the backs of existing things exploring things and making records of things in such as sedimentary deposits, celestial light trails of distant things moving through time, books in libraries, photos of our ancestors...
Okay...so we have to believe existence has been around for a long time and there is no denying that really...all this stuff around us tells us so...but what if someone doesn't know all that stuff? They might just be in a small circle. But a spiral? Sheesh...reincarnation for some folk who go that way? Cool...a never ending stage upon which to play any amount of characters in any amount of forms? Why the heck not!
Personally, I got my allotted time and that's it. Might as well let it unfold as it will and take the fork in the road when there's no spoon to scoop me up...sit by the corner for a spell instead of going left or right and catch a lift on a bus that's going off-road...and always carry a water balloon! You never know when someone has a whiskey balloon.
Well...I might have gone off the reservation on the Holographic Universe just then...or did I? %)
