The atheist believes in the Big Bang...
That Everything came from Nothing.
A variation of the god of the gaps fallacy.
And it's both Scientific and Theistic.
backstory...
Growing up, I didn't attend 'church' except a little when visiting relatives.
Most of my 'learning' came thru whatever was the prevailing culture in America at the time.
I'd had the standard US public education (40's - 50's) up to high school and then I joined the Air Force.
During tech school training in Denver, I was dating this local girl who lived close to the base.
One crisp fall evening, we'd been watching the boob tube - Late Night Movie. It was about some miracle(s) at Lordes. Now the girl was interested in the movie, while I was more interested in trying to do things that'll getcha in a position to NEVER be considered for the Supreme Court. Needless to say; I knew as much about the female gender as rocket science; so at least SHE'LL will never be able to Kavanaugh me!
Anyway; upon leaving her house early in the morning, I was walking back to the base; about 1.5 miles IIRC; thinking of the movie. Sorry; but I could not see any 'god' in those healings or whatever.
I was a rational sort; the kind that put his faith in what I could figger out for himself. I went clear back to the teaching I'd gotten about the Big Bang and evolution and the stuff that school wants you to understand.
The clear Colorado night sky was ablaze with stars in that mile high air. "Yeah!", I thought. "After the BB everything was formed and earth and everything came to be and the primordial goo got to churnin' and then little squally things came to pass and then the fishys and the birds and the cows and the apes and finally Man and then ME!"
That Einstein was RIGHT!
E=mc2 explained it all!!
Happy that a vexing movie was now debunked; I continued toward the base, mulling over mass and energy and light (Darn near none of which did I really understand).
Happy that Einstein's equation had gelled my thoughts on the problem, my analytical brain coughed up the fact that equations can be re-written and they are still true.
Thus E=mc2 could be rearranged to be...
m=E/c2
So there it was; all that MASS in the universe; all them stars out there; all them planets and moons and meteors and bugs and birds and me - all MASS!
As I neared the guard at the gate; an idea, a thought, a whisper, or a Voice said to me, "So... where did the ENERGY come from?"
