I am not discounting you story of creation that is not my intent, but none of my bibles mention the Big Bang? I don’t really care how the universe began, what I do care to point out here is that the very same people who say it has nothing to with GOD (who they don’t believe in) have been saying for years the BIG BANG Is gospel…… now there gospel is crumbling. I would think that the multiverse or multiple dimensional theory is more plausible it would explain a heaven that we can’t see in out dimension.Perhaps, but in most cases with science, we have to remember that it is "scientists" that are saying such things, not science itself.
"Scientists" have even put forward ideas that there are multiple universes, although they can't answer how those came about either.
Personally, I'm going with the Biblical story of the creation of the universe, but in almost any "supposed" theory as to how it happened, it still could have been God that did it "that way."
