From my point of view, the world and the universe came into being when I first precieved it. As others explained to me what they knew of the phenomenon and all accompanying phenomena, that seemed reasonable and it modified my view. And then I discovered quantum mechanics and all that entails. Throw in psychology, philosophy and religion, metaphysics and grain alcohol and you have a wonderland where just about anything can happen and if not in this universe then in the next one, or the next.

I imagine when I wink out of this plane, it will all cease to exist. Reason tells me "no" but experience tells me "yes".
