Life is what you make of it. Having faith or not does not stack the deck any differently, and in the end, we end up like all the others. What I don't understand though, is what kind of person is it that finds life utterly devoid of purpose without faith? I wake up in the morning with the desire to do great things and to build the future, faith or no faith. Of course, the very concept of "purpose" is biased by the subjective; purpose is what you make of it. I find purpose in exercising my abilities to push the envelope of human existence. It may seem purposeful to me, and perhaps to other humans with the same experiential context, but I don't for a minute believe that what anyone does has a purpose that is objectively meaningful in the universe. The very concept of "meaning" is implies the subjective.
I take it you didn't have a source to support your something from nothing addendum to the Casimir Effect?
The Casimir effect was the only valid example I could think of off the top of my head that someone could relate to without digging into the nasty technical stuff. Transient photons are not the most intriguing particles, though it is a valid example of the behavior in question (things spontaneously popping in and out of existence). Part of the problem is that we don't really know much about this particular class of phenomena, nor how to manipulate it. Of course, by the very definition of spontaneous creation we can't "cause" it to happen, but we can filter the behavior. Its all deep weird physics that would allow us to plumb the very nature of the universe if we could ever figure it out, but unfortunately these types of particle fields have many properties that make them all but undetectable by direct methods which has hindered research.
