My "faith" in what I know is subject to change with new evidence. So, I take it for what it is, a current state of knowledge. If I were an atheist then my faith would be of equal character if not caliber as that of the so-called believers, For atheists believe there is no God as much as believer believe there is. They have unshakable faith (trust) in their belief. No rational being, in my opinion, can be 100% sure in something that has no proof, or even a definition for that matter.
"With each passing a unique creation is erased never to appear again."
Mathematically we may show that with a change in geometry, temporal locations you assume to be gone 'never to appear again' are accessible and as such are 'again'.
Sure, with impossible assumptions everything is possible. The likelihood of it is however less than nil. I can design a perfect optical system than can never be made, which is not worth the paper it was designed on because it has no practical or real value. Likewise, what is probability than a supernova can be reconstituted to its infancy? And if it is, it would still be a new creation, a mere clone of itself.
